Figure 1-1 RCP-GPIO Control Panel (Front and Rear Views)

1.2  General Description

The RCP-GPIO Control Panel is a specialized control panel that can take electri-

cal switch closure inputs and generate electrical switch closure outputs for use in

interfacing with external electronic equipment.

The RCP-GPIO Control Panel can be configured to operate in a variety of selec-

tion modes. The RCP-GPIO Control Panel offers 32 inputs and outputs that can

be configured to generate switches on the PESA router as well as generate tally.

The RCP-GPIO Control Panel comes packaged in a standard 19" two rack unit

chassis requiring 3" of depth. Power is supplied to the control panel through a

plug-in-the-wall type power pack.
