ST.TM.E10033.3
RS-422 supports nx64 kbit (up to 2.048 Mbit/s) or nx56 kbit (up to 1.792
Mbit/s) data rates where n = 32 max. The RS-232 input can support data
baud rates of 1.2 k – 38.4 kbaud. RS-422 data can be time-delayed for
synchronisation. The time-delay is only accessible via the debug terminal
of the MCE.
Menus associated with this module are given in Section 3.9.5 in Chapter 3.

NOTES…
Empty module slots, except for slot 2, must be fitted with a blank module (S8445) to enable the correct
air-flow through the equipment. Slot 2 (see Table 1.7) can be fitted with a blanking plate (S8500)
alone.
1.6.2 RAS Scrambling Module (M2/EOM1/RAS)
The RAS Scrambling Module (S8489) is used to scramble the services in a
transport stream so that unauthorised users are denied access. It uses
TANDBERG Television’s proprietary Remote Authorisation System (RAS 1)
which supports two methods of key entry: SNG Key mode or Fixed Link
operation. The module can be located in option module slots 2, 3 or 4.
In SNG Key mode, a seven digit key is entered via the front panel on the
Encoder. In Fixed Link mode, an 8 digit key is assigned by TANDBERG
Television and pre-programmed into the Encoder and IRD. Scrambling can
be switched on and off under user control.
The input to the module is the Motherboard (Base Board 3ASI) Multiplexer
output via the backplane. The output is presented on the backplane as well
as three dedicated ASI outputs. The backplane output is used when further
processing is to be performed on the scrambled transport stream.
Examples of the backplane output being used would be when a RAS
Module is used in conjunction with an Internal QPSK Module or ATM
Interface Module. Three ASI outputs are provided, so that in addition to
the output, both monitor and redundancy connections can be catered for.
Menus associated with this option are given in Section 3.9.7 in Chapter 3.
