Error responses
When the switcher receives a valid 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 contains invalid parameters, it returns an error response to the host.
Error response codes are:
E01—Invalidinputchannelnumber(outofrange)
E06—Invalidinputchannelchange(auto-switchmodeactive)
E09—Invalidfunction(mode)parameter
E10—Invalidcommand
E13 — Invalid value (out of range)
