Switcher-initiated messages

When a local event such as a front panel operation or error condition occurs, the switcher responds by sending a message to the host. The switcher-initiated messages are listed below:

(c) Copyright 2008, Extron Electronics, SW4 3G HD-SDI, Vx.xx]

The switcher issues the copyright message when it first powers on. Vx.xx is the firmware version number.

Inn]

The switcher sends the Inn message whenever the selected input is changed using the front panel buttons. “n” is the input number.

Error responses

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

E01 – Invalid input channel number (out of range)

E06 – Invalid input channel change (auto-switch active)

E10 – Invalid command

E13 – Invalid parameter

Timeout

Pauses of 10 seconds or longer between command ASCII characters result in a timeout. The command operation is aborted with no other indication.
