Host-to-Switcher Instructions

The switcher accepts SIS commands through its RS-232 port and/or its Ethernet
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 switcher response to an SIS command ends with a carriage return and a line
feed (CR/LF =
is one or more characters.

Switcher error responses

When the 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, the switcher returns an error response to the host. The error
response codes are:
E01 — Invalid input channel number (too large)
E10 — Invalid command
E11 — Invalid preset number (zero or too large)
E12 — Invalid output number (zero or too large)
E13 — Invalid value (out of range)

Using the command/response table

The command/response table begins on the next page. Except for the gain and
attenuation settings and the filter settings, upper or lower case letters are acceptable
in the command field. Command and response examples are shown throughout
