2.7 System Wiring

The Rackmount controller can be configured to control pan and tilt positioner systems and third-
party equipment. This section overviews and describes the electrical wiring and pinouts for the
Rackmount Controller.

2.7.1 Data Input Connectors

The Rackmount Controller is equipped with both an RS485 (half-duplex) input and USB input.
The RS485 (half-duplex) input connector is a 4way XLR Connector. The USB input connector is
a USB type B connector. Both the RS485 and USB connectors accept Pelco D protocol
commands for controlling the positioner and discrete outputs. For a list of Pelco D commands
compatible with a Will-Burt positioner see the Positioner manual. For a list of Pelco D
commands to control/activate the digital discrete outputs from the 9-pin connector on the back
of the Rack Mount Controller see Table 3-1 of this manual.
