Introduction
Instruction Manual: TT1260 Standard Definition Professional Receiver/Decoder Page 1-9
ST.TM.E10100.1
There is a 25-way D-type connector on the optional Alarm Relay Card
(TT1260/HDC/ALRM) with six relays for failure monitoring for NCP over-air.
The operator can define (using the Alarm Menu pages) which alarm
conditions that drive the relays and also the general front-panel ALARM
LED. This is described in Chapter 4, Alarms and Annex C, Menus.
1.2.4 Conditional Access and Scrambling
The transport stream received by the IRD may be encrypted. The CA
system is used to decrypt the required components of the transport
stream so that they can be decoded.
The following Conditional Access and Scrambling options are available for
the TT1260 range of Satellite Receivers and Decoders:
· No Conditional Access
· Basic Interoperable Scrambling System (BISS) Mode-1 and Mode-E
only.
· VideoGuard Director and BISS
· Remote Authorisation System (RAS) and BISS
· VideoGuard Director, RAS and BISS
· Signal Protection
When the CA system uses a Smart Card, access by the user is via the back
panel of the IRD.
