This port is independent of the rear panel Remote port and is not affected by
changes to the rear panel port’s protocol. This front panel port’s protocol can
be changed, under SIS command control only. See the Command/Response
table for IP SIS commands, later in this chapter, to configure both ports under
SIS control.
