4.2.3 Antenna Motor and Limit Switch Connections
The motor conductors should be sized appropriately for the motor load. Three conductor cable should be
used so that the ground terminal of the motor can be connected to the ground lug in interface box. The
limit switch conductors carry very little current, a pair of 20 to 18 gauge conductors are sufficient for the
limit switch connections.
5.3 RC2000 CONFIGURATION
Via CONFIG mode, the user can optimize the operation of the controller for use with the interface box.
Certain CONFIG mode items must configured in a certain manner to insure proper operation of the
interface box. Other CONFIG mode items can optionally be configured so as to optimize the operation of
the controller for use with the interface box.
4.3.1 Required CONFIG Mode Settings
A number of RC2000 CONFIG mode items must be configured properly for reliable operation of the
RC2000 with the interface box. Here is a list of those items ...
CONFIG Required Value for
Mode Item Operation with
Interface Box
Azim Slow 254
Speed
Elev Slow 254
Speed
Simultaneous 0 - DISABLE
Az/El Enable
Az/El Slow See the comments.
Deadband
4.3.2 Optional CONFIG Mode Settings
The Az/El Drive Options CONFIG mode item controls access to the antenna movement parameters. The
antenna movement parameters control the movement of the antenna (i.e. the number of attempts which will
be made to hit a target position, the maximum allowable error, the coast distances, etc.). The default
movement parameters of the RC2000 are optimized for antenna's powered by 36 volt linear actuators. In
almost all cases the default values for these CONFIG mode items are not appropriate for antennas
powered by other types of motors. Most antennas used with the interface box have drive systems with
more inertia and more counts per degree of movement than antennas powered by 36 volt linear actuators.

Comments
A slow speed value of 254 disables the RC2000's pulse
width modulation based slow speed system. Failure to
properly configure this CONFIG mode item can result in
damage to the interface box.
A slow speed value of 254 disables the RC2000's pulse

With the RC2K90INT-1, simultaneous azimuth and
elevation movement is not allowed. With the RC2K90INT-
2, the user will generally want to enable simultaneous
azimuth and elevation movement
The value of the Az/El Slow Deadband item should be set
to approximately the same value as the Az/El Fast
Deadband for interface boxes which only support single
speed azimuth and elevation movement. Please see the
discussion of these CONFIG mode items in the next
section.
