Used to request or yield Active status. The 'Px' argument specifies the
port that XDS activity will be set to, i.e. P1. Port P3 can set the Active
status of any port. The other ports can only request active status for itself
and so does not need to enter the Px parameter. Active status can only
be obtained if the port has been authorized in the Permission List.
Only one port can be active for each Data Type at a time. If another port
is already active the E1 error message will be returned. If the command
is entered with the override parameter O, the port entering the command
will become active in place of the previous active port.
Creates an XDS packet and loads it into the XDS queue. The Encoder
will begin inserting the packet immediately.
 Packet sets the XDS Class and Type of the packet that will be
created. If a new packet is loaded with the same Packet ID as an
existing packet in the queue, the pre-existing packet will be deleted;
if the new packet is a Program Name or Program ID packet, all
program-specific packets will be deleted from the queue. A packet
loaded into the Encoder with the Load XDS Packet command has
local priority; in output signals, it will replace all upstream packets
of the same Class and Type.
The Packet parameter should be entered as Class immediately
followed by Type in the way shown in the table below. Leading
zeroes may be omitted.
The Class and Type of a few of the most commonly used XDS
packets are shown in the following table; for a complete list refer to
CEA-608B.
