64 Seed Hawk® Viper Pro™ Installation & Operation Manual
Product Application
The product application feature allows the Viper Pro to:
• Control a Raven CANbus system
• Log application data such as coverage and rate information
• Control product application according to a prescription map for variable rate control
CANbus Rate Control. The Viper Pro field computer is capable of controlling product application directly via a
Raven CANbus using Raven product nodes. Each node provides a single control channel for controlling the
application of a single product. So, if the Viper Pro is connected to a CANbus with a single product node, the
Viper Pro will monitor or control for one product during an active job. Up to five product nodes may be
connected to the Viper Pro to control any combination of liquid, granular, injection or spinner channels as
necessary. In this configuration, the Viper Pro is directly controlling the product control valves and other
hardware.
Note:
A multi-product variable rate key must be purchased and authorized in order to provide multi-
product VRA within a job. Contact a local Raven dealer to acquire the activation key and refer to
the Registering the Viper Pro section on page 21 for assistance entering the activation code on the
Viper Pro field computer.
Swath Guidance
When the swath guidance feature is enabled, the Viper Pro may provide on-screen guidance paths based
upon the programmed machine or equipment width. The swath guidance path displayed on the Viper Pro
provides a quick reference to the vehicle location in relation to previous coverage and may be used with an
automated steering system such as the Raven SmarTrax or SmartSteer systems to automatically steer the
vehicle using the displayed guidance path.
The Viper Pro is capable of providing guidance for several crop or field patterns to suit field conditions and
application types.
Section Control
The Seed Hawk Section Control (SCT) feature allows the Viper Pro to automatically turn the sections on or off
by referencing the coverage map. While Viper Pro creates the coverage map, the SCT system references
previously applied areas and the vehicle location to automatically turn sections off in turn as the implement
crosses over previously applied areas. As sections re-enter un-applied area, SCT turns the section back on.
SCT initially creates a 5 MB file with a .bct extension that contains detailed information about the section
coverage for a specific job. Viper Pro saves this file in the Coverage folder on the internal storage memory. If
the field exceeds the size of the original file, Viper will automatically increase the file size to cover the entire
field area.
See Chapter 9, Sectional Control Technology™ (SCT), for more information on using the SCT feature with the
Viper Pro field computer.
