Error responses
When the PVS switcher receives a valid SIS command, it executes the command
and sends a response to the host device. If the PVS is unable to execute the
command because the command is invalid or it contains invalid parameters, it
returns an error response to the host.
The error response codes and their descriptions are as follows:
E01 – Invalid input channel number (too large)
E06 – Invalid channel change
E10 – Invalid command
E13 – Invalid value (too large)
E14 – Invalid command for this configuration
Using the command/response tables
The command/response tables in this chapter list valid command ASCII codes, the
PVS’s responses to the host, and a description of the command’s function or the
results of executing the command. Upper and lower case characters may be used
interchangeably in the command field unless otherwise specified (setting gain/
attenuation, for example).
The ASCII to hexadecimal (HEX) conversion table below is for use with the
command/response tables.
