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)
