Using the TT1222 with the Director System

E.2.6 Force Service Selection

Force’s the receiver to select a different service on the same frequency and LNB

input. Only the service selection is required for this command.

If the service fails to decode, the receiver will tune to the Emergency Home Carrier

if valid.

E.2.7 Set Emergency Home Carrier

Set the service parameters to use in the event of decode failure. Where the current

service selection fails to decode and the receiver is in OAC control mode then if the

Emergency Home Carrier has been defined, the receiver will tune to this service

after a specified timeout. The timeout for Emergency Home Carrier is defined when

sending this command.

Setting the Emergency Home Carrier allows a failure situation to be recovered,

particularly since the receiver can only accept Director commands from a carrier that

contains them.

E.2.8 Set Relays

Switches the general-purpose alarms. 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.
