ADCP-50-304 • Issue 19 • June 1999 • Section 2: Functional Description

A remote control device can control the operation of up to 16 full PS chassis assemblies (16 modules each) using a dedicated communications channel. This channel has four signals:

1.Transmit Data (TD)

2.Receive Data (RD)

3.Clear-To-Send (CTS)

4.Request-To-Send (CTS)

Each of the above signals has the same function as the corresponding signals defined by the RS- 232 standard.

The communications channel transmission medium is a cable consisting of four twisted wires within an overall shield. The shield is ground potential.

Note: The electrical characteristics of the communications channel cable (9-wire) conform to RS-422A/V.11 (X.27) standards.
