NThis port is independent of the rear panel Remote port and is not affected by changes to the rear panel port’s protocol. This front panel port’s protocol can be changed via SIS command control only. See the Command/Response table for SIS commands, later in this chapter, to configure both ports under SIS control.

Host-to-Switcher Instructions

The switcher accepts SIS (Simple Instruction Set) commands through either serial 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 2006, Extron Electronics CP 300 450 MAV IP, Vx.xx, 60-nnn-01]

The switcher initiates the copyright message when it is first powered on. Vx.xx is the firmware version number; nnn is the part number for your switcher model.

Qik]

The switcher initiates the Qik message when a front panel switching operation has occurred.

Sprnn]

The switcher initiates the Spr message when a memory preset has been saved from the front panel. nn is the preset number.

Rprnn]

The switcher initiates the Rpr message when a memory preset has been recalled from the front panel. nn is the preset number.
