Prescription (Rx) Maps
Prescription (Rx) maps may be loaded onto the Viper Pro field computer for automatic variable rate
applications based upon rate zones referenced within the prescription map shapefile. The Viper Pro is capable
of controlling up to ten products in reference to individual maps for each product or a single map containing the
prescription rate information for each product in the .dbf file of the shapefile format.
The following table is an example of the .dbf file for a single map that contains multiple product information.
Note:
In order to control multiple products according to a prescription map, a multi-product activation key
must be entered on the Viper Pro. Contact a local Raven dealer to obtain a multi-product VRA
activation key and refer to the Registering the Viper Pro section on page 27 for information on
entering activation keys on the Viper Pro field computer.
If the prescription map contains zero rate zones, the product node or control channel must have
either a PWM close or fast close valve controlling the corresponding product. Refer to the
Application and Control Valve Type(s) section on page 40 for information on setting the valve type
on the Viper Pro.
If the system contains a fast valve, the valve must be plumbed into the main product line. Do not
plumb the valve into a bypass line.
