The active input is chosen using the Input Status
Menu (#2). The specification for this connector is
given in Annex B, Section B.4.2, 8PSK/16QAM
Satellite Receivers.

CAUTIONS...
1. The Receiver provides dc power (refer to Chapter 3, Operating the Equipment Locally) via the
active L-band input connector to drive an LNB (Low Noise Block Down-Converter). Do not connect
equipment other than an LNB to this connector. Failure to do this may result in damage to the
external equipment.
2. The F-type connector is not suitable for repeated connection and disconnection. When intended for
use in this way, fit a sacrificial connector and connect to it.
5.5 High Speed RS-422 Data Enabler Card
(TT1260/HWO/HSDATA)
5.5.1 General
The High Speed RS-422 Data Enabler Card provides RS-422 data output
when there are PIDs carrying high speed data in the incoming transport
stream.
High-speed data (synchronous data) can be carried in a transport stream
as private data. This is then extracted from the transport stream and
output from the IRD via the RS-422 interface. Data-rates in integer
multiples of 56 kbit/s and 64 kbit/s up to 2.048 Mbit/s (subject to the
number and type of services in the multiplex) are output on a 9-pin
D-type connector.
NOTE…
When the High Speed RS-422 Data Enabler Card (S12595) is detected on power-up the unit will
recover high-speed data. If not installed the unit will recover low-speed asynchronous data. The
TT1260 can recover either low speed (RS-232) data or high speed (RS-422) data but not both
simultaneously. For technical specifications see Section B.5.3, Data Outputs.
