Host-to-unit Instructions
SIS commands consist of one or more characters per field. No special characters are required
to begin or end a command character sequence. When a command is valid, the unit
executes the command and sends a response to the host device. All responses from the unit
to the host end 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.
Unit-initiated Messages
When a local event, such as an equipment power-up, occurs, the unit responds by sending a
message to the host. The unit-initiated messages are listed below:
(c) Copyright 20nn, Extron Electronics PowerCage FOX Tx HDMI,
Vn.nn, 70-889-nn]]
- or -
(c) Copyright 20nn, Extron Electronics PowerCage FOX Rx HDMI,
Vn.nn, 70-889-nn]]
The connected unit issues the appropriate copyright message (above) when it first powers
on. Vn.nn is the firmware version number; 70-889-nn is the part number of the connected
unit.
Reconfig]
The unit sends the Reconfig message whenever the video input signal to the transmitter is
changed.
1Lnknn•2Lnknn•Vidnn•Audnn]
The unit sends the status message whenever a change in the fiber link and video and audio
connection occurs. nn is the link or input status, where 0 = link or input not detected,
1 = link or input detected, and -- = not applicable for this unit.
EmbedAudn]
The unit sends the Embedded audio message whenever a change in the position of the
receiver HDMI Audio switch occurs. n is the switch position, where 0 = embedded audio is
muted and 1 = unmuted.
Error Responses
When the unit receives a valid SIS command, it executes the command and sends a response
to the host device. If the unit is unable to execute the command because the command is
invalid or it contains invalid parameters, the unit returns an error response to the host. The
error response codes are:
E10 - Invalid command
E11 - Invalid preset number
E13 - Invalid parameter
E14 - Invalid command for this configuration
