E.2.6 Force Service Selection
Forces the Receiver to decode a different service or stored channel (which
may require a retune). The command is generally used to hop between
services. The Director system has to be informed of the frequency,
FEC-rate and symbol-rate for each stream. This is set up using the
Multiplex Element Manager (MEM). (The Director User Interface and the
Director core require restarting to register changes that have been set in
the MEM.)
E.2.7 Set Emergency Channel
Sets the service to use in the event of a selection failure. Is activated after
a specified time has elapsed. If not set, the Power-up Channel is assumed.
Setting the Emergency Channel allows a failure situation to be recovered.
E.2.8 Set Relays
Switches the general-purpose relays. This command does not affect the
summary alarm relay.
E.2.9 Local Lockout
Locks out the LOCAL CONTROL mode but status information can still be
viewed. All Director commands are functional. The Receiver can be
unlocked locally using a PIN number or over-air using Allow Local Access.
E.2.10 Abort NCP Command
Aborts commands that have been sent but not executed. When a
command is received which has an expired execute time, it is acted on
immediately.
