4 Viper Pro Installation & Operation Manual
Viper Pro Features
The following sections offer a brief introduction to the capabilities of the Viper Pro field computer and some of
the optional features available for use with the Viper Pro precision application management system.
Speed Compensated Product Control and Datalogging
The Viper Pro is capable of controlling up to ten products through product control nodes connected to a
CANbus system. Viper Pro automatically adjusts the application rate of each product according to the speed of
the vehicle, width and status of programmed sections, and a programmed target rate.
The Viper Pro is also capable of monitoring and mapping applications controlled by another Raven serial
console, such as the Raven SCS 440 or 460 consoles, via a serial connection. Variable rate capabilities of the
Viper Pro may also be used with a Raven serial console.
A real-time, as-applied map is displayed on-screen while application and scouting information is logged and
saved by the Viper Pro. This “job” information can then be transferred to a home or office PC or the Slingshot
web site and used to create printed reports and coverage maps.
Variable Rate Application (VRA)
Viper Pro can provide automatic variable-rate control for liquid, granular, spinner control, anhydrous ammonia,
or injection products. Viper Pro will also datalog and store as-applied data or scouting information. This as-
applied information can be used to compare the field prescription to the actual application and provide valuable
documentation of the application. The Viper Pro system will store the application report and datalogged
information on the field computer until transferred to a USB flash drive or uploaded to the Slingshot web site for
creating or printing application reports or archiving application information on a home or office PC. See
Chapter 11, File Maintenance and Editing Reports, or Appendix B, Understanding Viper Pro Files, for detailed
information. The Viper Pro field computer creates application reports in both the common shapefile format
which can be used with many application management software packages and a bitmap (.bmp) file which can
be viewed on any computer without specialized software tools. The Viper Pro is also capable of outputting a
.jdp (job data package) for the Slingshot web service.
Single product VRA (Variable Rate Application) comes standard with the Viper Pro system. With the Multi-
Product VRA upgrade (P/N 077-0171-152), the Viper Pro system can variable rate up to ten products
simultaneously.
On-Screen Guidance
The Viper Pro system provides on-screen 3-D guidance in the form of a course direction indicator (CDI) as well
as an on-screen light bar. The guidance feature offers straight (A-B) line, last pass, fixed contour and pivot
swath patterns to match the field and application. In addition, GPS information may be sent to an optional
Raven external light bar. See Chapter 6, Viper Pro Guidance, for more detailed operation.
