PVS 305SA • Serial Communication

PRELIMINARY

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.
