Switcher-Initiated Messages - Extron electronics MAV 44 Series User Manual

Switcher-initiated messages

When a local event such as a front panel operation or an IR 501 command string
occurs, the switcher responds by sending a message to the host. The switcher-
initiated messages are listed below (underlined).
The switcher does not expect a response from the host, but, for example, the host
program might request a new status.

Vx.xx is the firmware version number. "nn" is the matrix size (such as 88, eight
inputs by eight outputs).
Qik
The switcher initiates the Qik message when a front panel or IR 501 tie creation has
occurred.

The switcher initiates the Spr message when a memory preset has been saved from
the front panel or under IR 501 control. "nn" is the preset number.
