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 =
), which signals the end of the response character string. A string
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 (too large)
E12 — Invalid output number (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. The
table at right shows the
hexadecimal equivalent of
each ASCII command.
With the exception of the audio gain and attenuation (G and g) and horizontal
and vertical filtering (D and d) commands, the SIS commands are not case
sensitive.
