Application Controls

AccuFlow™ and AccuFlow HP™ Plus

Q: How do I set my meter cal if the tag on the flow meter only tells me gallons?
A:

You need to divide the number on the flow meter by 4.22. e.x.710/4.22. Your rate will be in pounds of actual N per acre using this method.

Q: How much pressure drop from tank to cooler should there be?
A:

Pressure loss is measured by the pressure gauge on the Accuflow™ system. Look at the gauge on the system when the system is off and note the pressure reading. Start applying, look at the gauge and note pressure reading. If there is more than a 5 PSI difference there is a problem in the supply side of the tank.

Q: How long should the hoses be from my manifold to my knifes?
A:

All hoses should be the same length. Whatever the length of the longest hose is from manifold to knife should be the length of all the hoses.

Q: What size screen is in the strainer?
A:

A 20 mesh screen is what Raven suggests for the strainer.

Q: What is the part number for the gasket on the cooler?
A:

The gasket only part number is 219-0000-142C.
If you want the kit the part number is 117-0171-121.

Q: How are the NH3 valve with the 4-pin round connector pined out?
A:

On/Off valve connection

  • Pin 1 Ground
  • Pin 2 Signal
  • Pin 3 Not used
  • Pin 4 12v power

Control valve connection

  • Pin 1 Ground
  • Pin 2 Inc
  • Pin 3 Dec
  • Pin 4 12v power

Sidekick™ and Sidekick Pro™ Direct Injection

Q: Why doesn’t my pump run?
A:
  • With a Sidekick Console, the 115-0171-130 console cable could be installed backwards.
  • The 30 amp breaker could be tripped.
  • Controller not seeing boom sense.
  • Pump motor is bad. This can be checked by connecting to an alternative 12V source such as a battery.
Q: Why does my pump run wide open?
A:

Go through these procedures to test the Tach Generator:

  1. Put in manual and see if pump speed can be increased or decreased manually.
  2. While pump is running, check for output voltage from the Tach Generator. You should see an output of at least 9V.
  3. If the output is less than 9V the Tach Feedback Generator will need to be replaced.
Q: Why am I getting a Flow Alarm?
A:
  • Material caught in the Check Valves.
  • Shuttle movement restricted by chemical residue.
  • If operating at a low rate, may need to adjust the flow sensor.
  • Bad flow sensor. You can check cabling going to flow sensor by checking voltage: Pin A =12V, Pin B = 5V, Pin C = Ground. If you have a Sidekick Console, you can jump between pins A and B and the Run light will flash on the console.

Note: Regular pump maintenance is very important to avoid residue build-up within the pump itself.

Q: Why am I getting a Vac Alarm?
A:
  • A restriction from chemical tank to the injection pump.
  • It could be material in the tank itself.
  • A collapsed hose.
  • Plugged strainer screen.
  • Hand valve turned the wrong way.
  • If not a restriction, it could be a bad vacuum switch. Test for continuity between pins A and C. If OHM meter reads a short, the switch is good. If it reads open, the switch is bad.
Q: How do I maintain my pump?
A:
  • When flushing the pump it depends on the base of the chemical that is used. If a fuel-based chemical is used such as N Serve, fuel oil or kerosene is recommended. If a water based (Instinct) or lesser volatile product (Roundup) is used, water should be fine.
  • When storing the pump for the off-season, a 50-50 antifreeze is recommended.
  • Replacing the seals in the pump periodically (depending on the type of chemical such as N Serve or Instinct: annually) is recommended. The Seal Kit part number is 117-0159-987.

Boom Controls

AccuBoom™

Q: Do I need a serial or CAN kit?
A:

The main console used will determine which kit needs to be ordered. Example, if the machine has a SCS 460 console and a Cruizer II they will need to order the machine specific serial AccuBoom kit. If the Envizio Pro™/Viper Pro™ is doing the product control then they will need to order the CAN AccuBoom kit.

Q: Will AccuBoom work with a Cruizer I™?
A:

Cruizer I™ does not have the ability to control AccuBoom. The customer will need to purchase a Cruizer II™ which has CAN capability.

Q: What does the Turn Off Percentage setting do?
A:

This setting represents the total percentage of that particular boom section that must cross into a field/spray boundary or previously applied area before AccuBoom will control that section. If the value is set to 0% the booms will not turn off automatically.

Q: How do I set my Turn On and Off Look Ahead times?
A:

These values can be set by either time or distance. When set to time the field computer will scan in seconds, and when set to distance it will scan in feet. The field computer uses the settings to scan that far in front of the vehicle’s current position for spray zone map features and previously applied areas. This setting is used to compensate for the boom valves to open/close to avoid spraying undesirable product in these areas. These settings should not exceed 5 seconds.

Q: What does the Aggressiveness setting do?
A:

The aggressiveness factor uses the user set look-ahead values to adjust the response for sections at the end of larger booms or aggressive maneuvering when turning around in the headlands. Higher aggressiveness settings will increase the override time preventing from having the outer sections turn on/off while turning around aggressively on the headlands causing skips/late section engagement.

AutoBoom®

Q: I want to get 2 more sensors on my UltraGlide to make it a 5 sensor system, which kit do I order?
A:
  • If you are ordering a new kit, choose the dual sensor kit found under the heading “For Systems with Inner & Outer Sensor Connections” in the price book.
  • If you are ordering for an existing kit, how many connections are being used in the AutoBoom node?
    • If only 1 connection is being used, then you will need to order a kit under the heading "For Systems With A Single Node Connection."
    • If 2 connections are being used, then order a kit under the heading "Systems with Inner & Outer Sensor Connections."

For example: I have a 2009 Rogator that I am ordering AutoBoom for and I want 5 sensors. It doesn’t have any AutoBoom components on it now, which kit do I order?

The kit this customer will need to order is: 117-0137-031. In the price book it states that he would need to order the 117-0137-030 kit according to what has been said above, but in this case, we don’t need to order the 117-0137-030 as it has an extra sensor cable in it that we won’t use. The current after-market kit that he would order will have all 4 sensor connections in it and would populate 2 connections on the node, so we don’t need to order the 117-0137-030.

Q: I want to order a wheel kit to put on my machine with my UltraGlide system. What kit should I order?
A:

To order a full kit with axles, wheels and mounting brackets, look in the AutoBoom section of the price book in the “CAN UltraGlide” area under the heading "Standard Gauge Wheels (Optional)." Find the appropriate kit for your machine. This kit will come with axles, wheels and mounting hardware and brackets for your machine.

Q: What software do I download for my PowerGlide Plus or UltraGlide node?
A:
  • For Raven PowerGlide Plus and UltraGlide, download 4.0 software from www.ravenhelp.com.
  • For Raven ISO PowerGlide Plus and UltraGlide, download 4.0 ISO software from www.ravenhelp.com.

Be sure to read carefully whether the version that you are downloading is for the correct node that you are using whether it is a Raven standard node or an ISO node as the software versions will not cross over between nodes and allow the node to function properly after the update has been made. If the wrong software is loaded onto the wrong node, it will have to be sent in to repair to be re-programmed.

Q: How do I know what kits I need for an ISO AutoBoom system?
A:
  • The first kit ordered will be the controller kit. This is found on the first page of the AutoBoom section for Powerglide Plus and UltraGlide.
    ** It is very important to look at the first page of ISO choices in the price book to determine the correct controller kit for ISO systems. The customer will need to know what model of tractor and what controller they are using and also if they are using product control or not through the ISO controller. Pick the correct kit by reading through each kit to determine which kit fits the appropriate machine. For example: Is the ISO controller is a John Deere tractor or is it in a self propelled sprayer.
  • The second kit ordered is the machine specific kit and we order the same kit, as you would for any other AutoBoom kit.
  • One thing to note is that you will need to pay attention to whether it is a pull type machine with product control or not. If so, you will need to order the John Deere ISO to Raven ISO cable adapter 115-0171-991, and you may also need to choose an ISO Implement Extension Tee Cable.
Q: What do I need to update my Powerglide Plus to UltraGlide?
A:

Pick the correct kit based on the style of hydraulic block currently on your machine. For example: There will be a different kit depending on whether you have square coils (older style) or round coils (newer style) on the block. When the price book states square coil/round coil, have the customer look at the shape of the coils on the proportional cartridges and blockers on the AutoBoom block itself.

These kits include all materials needed to upgrade the customer’s system.

  • node
  • cables
  • sensors
  • parts to add to hydraulic block

SmartBoom™

Q: Can I use a non-Raven GPS with a SmartBoom™?
A:

The SmartBoom console can use GPS from any source, as long as it can provide the NEMA strings GGA and VTG at a minimum of 4 Hz, but 10 is recommended.

Q: Can I use SmartBoom™ with XXXX console?
A:

The SmartBoom™ comes with cables for the Raven 440, 450, 460, 660 and 660M. It ties to these consoles with a special cable. It may also interface will the Cruizer™ or Cruizer II™.

Q: What position do my boom switches need to be in to work?
A:

The master switch should be on, and the individual boom switches off.

Q: Can I use SmartBoom™ with a non-Raven console?
A:

Yes. Set the console to none and master to remote. Use the universal or machine specific cable, and provide a master switch.

Q: What do I need to order for SmartBoom™?
A:

The SmartBoom™ is a fairly simple install. Only a GPS source, the controller and a cable is required. You will either require a SCS console cable, a machine specific cable or a universal cable.

Field Computers

Envizio Pro II®

Q: When is a CE6 Activation Key needed?
A:

When updating to 3.2 or higher and when the software version was lower than 3.2. The Envizio Pro™ must be at least 2.3 prior to inserting key.

Q: What kind of file types does the Envizio Pro™ export?
A:

Envizio Pro™ will export a .bmp that will open with most desk top software, shape files that will require GIS software and .jdp which will require a free Slingshot Viewer Account to view.

Q: Can I replace my SCS console with an Envizio Pro™?
A:

Yes, there are specific adaptor cables to connect to the existing SCS consoles 440, 450, 460, 660, 661, 4400 and 4600. You would also have to add a Boom/Speed and Product Node. If you have SCS 440, 450 or 4400 then the addition of a Switch Pro may be the best solution.

Q: How many products will the Envizio Pro™ control?
A:

Envizio Pro™ will control up to 4 products, SmartYield™ and OmniRow™.

Q: My sprayer has 2 PSI transducers one for pump pressure and one for boom pressure. Can the Envizio Pro™ display both?
A:

Yes, it can as long as the machine has the correct product cable.

Viper™ and Viper II™

Q: How do I update software?
A:

Software updates and instructions can be found on ravenhelp.com for Viper II™ or Viper Pro™. This will display the current and previous version along with installation instructions.

Q: My boom is not painting correctly, how do I adjust boom setup and boom select?
A:

Check the boom setup is correct for the machine (Menu/Setup/Boom) and that the proper booms are selected for the product (Product Control/ Boom Cals).

Viper Pro™

Q: How do I set a Viper Pro™ to do product and spinner control?
A:

On the Viper Pro™ screen select Menu, Setup, Booms.

  1. Set the overall width and the number of sections will be 2, one for product control and one for spinner control. Select the Next icon.
  2. This will to the Boom Section Setup page. All the sections will have the same width entered. Example overall width is 720”. All the sections will have a width of 720”. Select the next Icon. You will get a Boom Setup Warning, select No. You may get another warning, select No.
  3. Now you should be at the Boom Setup Summary page. On the bottom portion of the page is the Boom Section Summary. Touch on Boom 1.
  4. You will be now at Boom Section 1 settings. The section width will need to be the same as the overall width entered on the Boom Setup page and the Left/Right will need to be changed to 0. Select next and do the same for section 2. When complete select ok, and then ok to the Boom Setup Warning.
  5. You will see the boom sections are now on top of each other. Select ok to go back to the main Viper Pro™ screen.
  6. Next the booms will need to be associated with their product. Touch on Product Control, then in the upper left corner on the Boom Cals. There will have to be checks in Boom 1 for all the Granular Products being controlled and a Check in Boom 2 for the product that is the Spinners.
Q: After updating software the Rbin Viewer is not used. How do I view my Reports?
A:

With the newer software there are three options to view the reports.

  1. In the Reports folder there will be a .bmp file that will open up on most computers with desktop software like Microsoft Paint.
  2. The second type of file you will find in the Reports folder is the shape files that can be used with GIS software.
  3. The last file you will find in the RDE outbox is a .jdp file. Jdp files are used with a free online Slingshot Viewer account and will output a report similar to the Rbin Viewer. Please visit www.ravenslingshot.com to sign up for a free Slingshot Viewer account.
Q: My Rx map is in tons. How do I apply in pounds?
A:

When setting up the VRA job you will get a Rate Conversions selection. This is normally default to 1.0. It will need to be changed to 2000 for pounds.

Q: Why is the coverage map small on the application report?
A:

This will usually happen when the job was opened on the Viper Pro™ on the way to the field or a distance away. To prevent this in the future, don’t open a new job until the machine is at the field associated with the job.

Q: Can my SCS 440 be replaced with a Viper Pro™?
A:

Yes, there are specific adaptor cables to connect to the existing SCS consoles 440, 450, 460, 660, 661, 4400 and 4600. You would also have to add a Boom/Speed and Product Node. If you have SCS 440, 450 or 4400 then the addition of a Switch Pro may be the best solution.

Q: I loaded Rx maps to my Viper Pro™ and when opening the job there are no Rx maps available.
A:

Two things to check. First, has the USB been initialized from the Viper Pro™ and the maps placed in the Rx Maps folder? Second, is there a .dbf, .shp and .shx file for each product?

Q: How do I get applied maps off of a Viper Pro™?
A:

This will depend on what version of software is running on the Viper Pro™. V3.3.14 and older will require the Rbin Viewer that is available on our webpage at the following location:

http://ravenhelp.com/Product%20Support/Field%20Computers/Rbin%20Viewer.aspx

If you have v3.4.0.26 or higher you will not need any software installed, and have 3 options for report outputs. The first is the .jdp file which works with ravenslingshot.com and is the replacement for the Rbin. Also the Viper™ will output a .bmp image and a .shp file that can be used with a shape file viewer or most ag software.

Included is a link to the current Viper Pro™ manual on our webpage which includes a good section (chapter 11 starting on page 175) on the file types and working with them.

http://ravenhelp.com/~/media/Product%20Information/Service%20Manuals/Field%20Computers/FieldComputersViper%20Pro%2034.ashx

Q: How do I put boom sense on to make the Cruizer™ paint with master switch?
A:

115-0171-792 will connect to port B.

Q: My touch screen is not responding.
A:
  • Try running a business card around the edges of the screen.
  • Recalibrate the touch screen.
  • Make sure the there is 12V from the center to the outer casing.
  • Make sure that the 5 amp fuse is good.

GPS Receivers

Q: How do I tell the difference between a Phoenix 300A and a Phoenix 300B?
A:
  • If you arrow over to the right one time from the home screen and see the SN# DABxxxxxxxx then it's a Phoenix 300A.
  • If you arrow to the right once, and down once, and see the SN# DABxxxxxxx then it’s a Phoenix 300B.
Q: I can’t get a GPS signal.
A:
  • Go into the WAAS configure screen and make sure it is set on satellite 133, 135 or 138.
  • Make sure the antenna has a clear view of the sky.
  • Make sure power and ground is good.
  • If that checks out, then cycle power.
Q: My receiver is stuck on “awaiting auth code.”
A:

Most likely, you have recently updated to new software and then added a feature such as RTK or Omnistar. If this happens you will need to get an auth code generated for the new software. This can be done through the Novatel website. You will need the serial number DABxxxxxxxx and the version (ie. 3.805) to generate a new auth code. This can be added through Ravenloader.

Q: Receiver is stuck on “initializing.”
A:

This usually happens when an error occurs during the update procedure. The Raven Product Support Group can send you a fix kit to download for the unit. After this is installed, reinstall the original update again.

Q: Viper™ says no GPS.
A:
  • If it’s a P200 make sure that you have the receiver connected properly to the Viper™ cabling or through SmarTrax™.
  • Do an auto baud on the Viper™, and see if it will see the receiver.
  • If yes, then go through the typical no GPS steps.
    • Double check to ensure the antenna cable is fully connected.
    • Make sure there are no obstructions around you (i.e. trees, buildings).
    • Make sure you are set to one correction satellite. Correction satellites are 133, 135 and 138.
  • Verify the GPS receiver has power.

SmarTrax™ and SmarTrax™ RTK

Q: When connecting a Cruizer™, Cruizer II™, Envizio Pro™, Envizio Pro II™ or Viper Pro™ to SmartSteer™ or CAN SmarTrax™, why does it say “Data Transfer in Process”?
A:

Language files loaded on the steering node must be transferred to the guidance console so they are updated. Most of this information is stored in the node and is meant to keep the list of machines updated in all the different foreign languages available. This process may take up to 10 minutes to complete the first time it is connected, but once completed it will not need to happen again unless the steering node software is upgraded.

Q: Is there a different way to do the calibration so I don't have to drive over so much area?
A:

6.0 node software does a much quicker calibration in a smaller area than previous versions. For the long box systems, there is no newer version that will take up less room to calibrate.

Q: Does Raven manufacture a steering kit for a machine not listed?
A:

Raven Industries is always looking at expanding the machines that we can steer. If it is not shown on the list, we encourage you to utilize the Ask An Expert form to communicate machine make and model requests.

Q: Which controller kit should be ordered for which machine installation kit?
A:
  • If running with a lightbar, Envizio or Envizio Plus, the only way to run autosteer is with the stand alone console kits.
  • If running with a Viper Pro™, Envizio Pro™, Envizio Pro II™, Cruizer™ or Cruizer II™ a stand along style kit will work, but the preferred system would be CAN.
  • If using Gen II cabling, there are only 3 controller kits to choose from. The key in selecting the right one is to note the 4 numbers in the middle of the hydraulic kit part number. They will be 0295, 4001 or 503X. This number indicates the style of hydraulic control valve being used and the cabling changes along with that.
  • If using Gen I cabling, there are several options for control node kits, but only for the 0295 and 4001 kits.
  • If a 503X kit is needed, the system will have to be at least partially converted over to Gen II cabling.
Q: Is the SmartSteer™ node interchangeable with the SmarTrax™ node?
A:

The SmarTrax™ node can be used in place of a SmartSteer™ node, but not the other way around. The SmarTrax™ node is built with the capability to run both types of steering systems, but the SmartSteer™ is not set up that way. The choice is not given while calibrating the SmartSteer™ for this reason.

Harvest Controls

SmartYield™

Q: How do I hook up the power cable on the SmartYield™ junction box?
A:

Hook the power cable to switched power, blue ground and brown power.

Q: How do I hook up the sensor cable?
A:
  • Brown = Power (Switched 12VDC +)
  • Blue = Ground (12VDC -)
  • Yellow with Green tracer = Signal
Q: How do I change the tilt configuration for optional mounting of J box?
A:

To optionally mount the J box with the face towards the front of the machine with the wires downward:

  • Flip the position of the Violet and Brown wires in the J box.
Q: How do I calibrate the moisture sensor?
A:

In the crop screen put in the value that you want to adjust the moisture by.

Q: How do I calibrate the yield sensor?
A:
  • Run the system through a full load of product with the system enabled and logging.
  • Weigh the amount of product harvested.
  • Enter the weight of the product and the amount displayed on the SmartYield™ system from the Calibration menu – Crop Screen.
  • Repeat this process. It usually takes two loads to accurately calibrate the system.

Planter & Seeder Controls

OmniRow®

Q: Hydraulic fluid is flowing out the breather port.
A:

Verify the hydraulics are not hooked up backwards.

Q: What are the Pulses per rev on Raven motors or OEM motors?
A:

Raven motors pulses per rev is 60.31, and OEM pulses per rev will be labeled on factory encoder.

Q: What is the Meter to Motor Ratio?
A:

For Raven installed systems:

  • Case is 2
  • White 2.2
  • Kinze 1
  • John Deere 1.47

For OEM motors you need to:

  • Locate the number of teeth on meter sprocket.
  • Locate the number of teeth on the motor sprocket.
  • Calculate the Meter to Motor Ratio. Divide “Meter Sprocket Teeth” by “Motor Sprocket Teeth.”
Q: How do I hook up to Ag Leader clutches?
A:

Ag Leader clutches don’t have a specific harness due to the many configurations the system uses.

The 115-3001-091 universal 16 clutch cable is used. Adaptor cables to meet length, and number of clutches will need to be custom made per installation.

For Ag Leader clutches:

  • If the wires on the clutch are both white then polarity doesn’t matter.
  • If the wires on the clutch are red and black:
    • Red = power and
    • Black = ground
Q: What is the speed Cal?
A:

The speed cal for OmniRow™ kits is:

  • 1000 if using CAN signal with internal GPS.
  • Standard speed cal with traditional radar. See the “Speed Calibration” section in Envizio Pro™ manual to determine speed calibration number if unknown.

OmniSeed™

Q: How many bins can be controlled?
A:

There are generic OmniSeed™ kits for Single, Two, Three, Four and Five Bin systems. In addition to the generic kits, brand specific install kits are also available for Bourgault, Morris, John Deere, CaseIH, Flexi-Coil and New Holland.

Q: Can liquid product control be added to an OmniSeed™ system?
A:

Yes, up to two liquid or NH3 products can be added, but the OmniSeed™ system is limited to 5 total products, liquid and granular combined.

Q: Does the OmniSeed™ system have blockage monitors?
A:

Optional Agtron run blockage monitors can be added. The OmniSeed™ system can monitor 2 loops of 120 sensors each.

Q: Are there bin level sensors with the OmniSeed™ system?
A:

Yes, the kits come standard with a low level bin sensor. Also optional ultrasonic bin level can be added.

Q: Does the OmniSeed™ have auto shut off?
A:

Yes, the OmniSeed™ system will do single section overlap control.

Slingshot®

Slingshot®

Q: Does the Slingshot® Field Hub and Slingshot® RTK work with non-Raven GPS and Guidance Equipment?
A:

Yes. Slingshot® utilizes industry standard RTK corrections. These standard formats are RTCM V3 and CMR+. As long as the GPS receiver accepts and can use one of these correction formats, Slingshot® will be able to provide corrections to it.

Currently, we have confirmed operation and have developed simple interface kits for the following non-Raven hardware:

  • Trimble EZ-Guide 500
  • Trimble CFX-750 (including CaseIH and New Holland branded versions)
  • Trimble FmX/FM1000 (including CaseIH and New Holland branded versions)
  • Trimble AgGPS 262 (Including CaseIH and New Holland branded versions)
  • Topcon AGI-3
  • Ag Leader/AutoFarm Paradyme

Most importantly, it's necessary for the GPS receiver to accept RTCM V3 or CMR+. Please contact the manufacturer of your GPS receiver to confirm compatibility.

Q: Does Slingshot® work with my John Deere GPS receiver?
A:

Unfortunately, in North America, John Deere receivers are not compatible with Slingshot® because they do not utilize industry standard RTCM V3 or CMR+ corrections.

Elsewhere in the world, John Deere receivers are compatible with Slingshot® and utilize the RTCM V3 message format. This allows John Deere receivers to operate on non-John Deere supported networks such as regional CORS networks.

Q: Can I use Slingshot® with CORS or Real Time Networks?
A:

Yes. Slingshot® is 100% compatible with third-party RTK networks such as CORS and MyWayRTK. To see what networks we currently work with, please see our RTK coverage map.

Q: Does Slingshot® use GLONASS?
A:

Yes. Slingshot® RTK base stations contain a survey-grade receiver capable of tracking both GPS and GLONASS satellites. The RTCM V3 message contains corrections for both constellations. Slingshot® does not charge extra for GLONASS corrections. As long as your GPS receiver is subscribed to receive RTK and GLONASS corrections, you can take advantage of them.

Q: I’ve heard RTK is not accurate past 12 miles from the base station, and yet Slingshot® RTK base stations claim a 30 mile baseline. How do you accomplish this?
A:

Before cellular technology delivered RTK corrections to the GPS receiver on the tractor, the 450 MHz or 900 MHz radios were the actual limiting factor in how far you could go from a base station to obtain RTK corrections. In truth, as long as you have a minimum number of visible satellites in common view between both the base station and the GPS receiver in the tractor, RTK corrections can be obtained at distances even beyond 30 miles. Slingshot® base stations incorporate the use of both GPS and GLONASS satellites in their RTK corrections to ensure an optimum number of satellites is in view at all times.

Q: What is the minimum number of satellites I need to have in common with a base station to have RTK fix?
A:

The current minimum is five satellites, and four of those five must be GPS satellites.

Q: Is using cellular technology reliable?
A:

Yes. Cellular technology has advanced a long way since its introduction in the 80’s. Most of the arable land in the world today has some level of cellular coverage. However, we also recognize that cellular coverage on farmland is often poorer than in cities. Because of this, Slingshot® has built in several redundancies into our solution to ensure the most consistent performance as possible. This includes a second cellular antenna on the Slingshot® Field Hub that we call “Diversity”. There are also several things we have implemented behind the scenes to ensure consistency, such as durable file transfer protocols, redundant off-site servers and intense software programs to optimize the delivery of data in harsh environments.

Q: What software companies use the Slingshot® API?
A:

Slingshot® currently partners with businesses to leverage the power of the Slingshot® API. We are letting these businesses announce themselves how they are (or will be) using the Slingshot® API. Companies that have announced their Slingshot API Community Partnership can be found at www.ravenslingshot.com.

To find out if your software can work with the Slingshot® API, we encourage you to contact the software company directly. If they are not participating in the Slingshot® API, ask them why not, and encourage them to visit the Slingshot® Community to learn how they can get involved.
