Extron electronic MSG0804 manual Host-to-MSG Matrix Switcher Communications, Addressing commands

Page 33

Termination resistors should only be turned on when operating in RS-422/ RS-485 mode, and then only for the first and last units on a long serial line. The default switch settings are all OFF. In half-duplex mode, only turn on one of the termination resistors, as they are connected together by the cable.

		- Where xx = 01 to 98

	[ADDR@]	Removes an address from the unit. This is the factory

		dafault setting.

	[ADDR?]	Query the unit for a previously assigned address.

		Connects the controller to the addressed unit. 00 is a
	[CCxx]	broadcast address and will connect to all attached units.
		- Where xx is the address of the unit to be contacted.

All serial commands are applicable to both the MSG0804 and MSG0808, except where the number of outputs differs between the two switchers. The MSG Matrix Switchers accept 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 delimiter ([) and an ending delimiter (]).

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 will need to assign an address for each unit.

The factory default for the MSG Matrix Switchers is no address. You must assign an address between 01 and 98. In addition, 00 is a broadcast address, and all connected units will perform the action commanded (no responses will be sent).

Using the command table

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