Extron electronic SWP123 manual Host-to-Switcher Communications, Using the command tables

Host-to-Switcher Communications

The SWP123 switcher accepts Serial Control Protocol commands through the RS-232/RS-422/RS-485 port. These commands consist of one or more characters per command field. They require a beginning character ([) and an ending character (]).

This unit does not work with standard Extron SIS commands.

Using the command tables

The command table is shown on the following pages. Lowercase characters are acceptable in the command field only where indicated. Command and response examples are shown throughout the command table.

Addressing commands

	In RS-232 mode, there is no need to assign an address to the switcher;
	however, if you are using RS-422 or RS-485 mode with several devices
	connected in parallel to a single serial port, you must assign an address
	for each unit.
	The factory default for the SWP123 Switcher is no address. If you want
	addressing, you must assign an address from 01 to 98. Address 00 is a
	broadcast address, and all connected units perform the action commanded
	(no responses is sent). Address 99 is reserved for future products.
	Once an address has been assigned to a unit [ADDRxx] the unit does not
	accept or respond to commands unless the commands are sent to the unit’s
	address [CCxx]. The unit accepts all commands issued to the specified
	address and sends responses.

	dafault setting.
