Remote Control Port (RS-232)

The MPS switcher RS-232 port connector is used to connect to a host or external controlling device, such as a computer or control system, which can generate the proper command codes and recognize the switcher’s responses.

The cable used to connect the RS-232 port to a computer or control system may need to be modified by removing pins or cutting wires. If unneeded pins are connected, the switcher may hang up. See chapter 2, Installation, for more information on wiring the connectors.

The RS-232 connector is a 9-pin D female with the following pin designations:

Commands and responses for programming the MPS 112 from a host system connected to the RS-232 port are listed on the following pages.

Host-to-MPS Communications

The MPS switchers accept Simple Instruction Set (SIS™) commands through the RS-232 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 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.

MPS switcher-initiated messages

When a local event occurs, such as a front panel operation, the

MPS switcher responds by sending a message to the host. The MPS -initiated messages are listed below (underlined).

Boot-up messages

Boot v1.00, (c)2002, ? to Enter

(c)Copyright 2002, Extron Electronics, MPS 112, Vx.xx

or

Boot v1.00, (c)2002, ? to Enter

(c)Copyright 2002, Extron Electronics, MPS 112CS, Vx.xx

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

Status change messages

The switcher issues status change messages as a result of front panel operations (actual or software-simulated). The status change messages are the same as the switcher’s responses to certain commands. See the last column of the table on pages 5-4 through 5-6.
