The switcher’s rear panel RS-232/RS-422 connector (figure 4-1) can be connected to the serial port output of a host device such as a computer, RS-232 capable PDA, or control system. This connection makes software control of the switcher possible.

Figure 4-1 — RS-232/RS-422 connector pin arrangement

The CrossPoint Plus Series Matrix Switchers are factory configured for RS-232 control. To use the switcher under RS-422 control, an internal cable must be moved. Refer to appendix B for the procedure for moving the cable.

The RS-232/RS-422 connector on the CrossPoint Plus Series switcher is a 9-pin D female connector with pin assignments as shown in figure 4-1.

The protocol is 9600 baud, 8-bit, 1 stop bit, no parity, and no flow control.

Host-to-Switcher Instructions

The switcher accepts SIS (Simple Instruction Set) commands through the RS-232/RS-422 port. SIS commands consist of one or more characters per command field. They do not require any special characters to begin or end the command character sequence. Each switcher response to an SIS command ends with a carriage return and a line feed (CR/LF = ), which signals the end of the response character string. A string is one or more characters.

Switcher-Initiated Messages

When a local event such as a front panel operation occurs, the switcher responds by sending a message to the host. The switcher-initiated messages are listed below (underlined).

(C) Copyright 2002, Extron Electronics “CrossPoint/Mav/Matrix”, Vx.xx

The copyright message is initiated by the switcher when it is first powered on. Vx.xx is the firmware version number.

RECONFIG

The reconfig message is initiated by the switcher when a front panel operation has occurred, an audio gain adjustment has been completed, or a memory preset has been recalled.

RAM Test Failed

ROM Checksum Failed

EEPROM Reset (Presets/Attenuators)

Serial EEPROM Reset (Current Settings)

Invalid Jumpers

If an error occurs during power-up, the switcher initiates one or more of the messages listed above.

All Configuration Memory Cleared

The memory cleared message is initiated by the switcher when a system reset has occurred. See System reset to factory defaults in chapter 3.
