Extron electronic MPS 601 manual Host-to-MPS Communications, MPS Switcher-initiated Messages

Host-to-MPS Communications

The MPS switcher accepts Simple Instruction Set (SIS) commands through the RS‑232 or USB configuration port. SIS commands consist of one or more characters per command field. They do not require 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 601-initiated messages are listed below (underlined).

Boot-up messages

(c) Copyright 20 nn, Extron Electronics, MPS 601, Vx.xx,nn-nnnn-nn ]

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

Status change messages

The switcher-initiated status change messages are a result of front panel operations (actual or software-simulated). The status change messages are the same as switcher responses to certain commands. See the last column of the command and response tables on the following pages.

MPS Switcher Error Responses

When the MPS switcher receives an SIS command and determines that it is valid, it performs the command and sends a response to the host device. If the switcher is unable to perform the command because the command is invalid or contains invalid parameters, it returns an error response to the host. The error response codes are:

E01 ] — Invalid input channel number (too large)

E06 ] — Invalid switch command (due to auto-input switch enabled)

E10 ] — Invalid command

E13 ] — Invalid parameter (out of range)

E14 ] — not valid for this configuration

E17 ] — Invalid command for signal type

E22 ] — busy
