Encryption
The WCI decryption option includes a secure microprocessor and a decryption ASIC. Different
levels of security may be implemented with software and ASIC changes.
2.3.11
Transport Output
The TRANSPORT output supplies the original received MPEG2 transport stream in
Synchronous Parallel format.
2.3.12
Option Modules for Expansion Ports
The IRD has two expansion slots Ð one high speed and one low speed. The high speed
expansion port provides the transport layer multiplexed stream while the low speed expansion
port provides the filtered packet data. An I
specifications for individual modules are included in documentation for the module.
2.3.13
AC Power
The unit features a universal-input power supply. AC line is fed into a standard IEC jack. The
nominal inputs are 115 or 230 VAC ± 10% at 50-60 Hz ± 2%. The total AC current
consumption with the 4:1 RF switch option and max LNB DC load is 0.8A at 115 VAC, and
0.5A at 230 VAC.
2.3.14
LNB DC Power
The unit may feed DC power to an external antenna-mounted LNB using either the RF-In
connectorÕs center-pin or a terminal on the rear-panel terminal strip (with an external DC power
inserter). The nominal voltage supplied is +17 to +24 VDC, while the maximum load current is
250 Ma. The output is short-circuit protected by a thermal fuse. A rear panel MODE DIP
switch may be used to activate/de-activate the DC output (See Section 2.4.2.1). An internal
jumper (J22) is used to enable/disable DC power on RF-In center-pin. (Therefore, to get DC
power on the RF-In center pin, both J22 and DIP switch must be set.)
2.3.15
Four Input / One Output RF Switch (Optional)
2.3.15.1 Description
The module is installed into the MODULE 2 option-slot position on the back of the parent IRD.
It allows the IRD to select one of four antenna / LNB inputs when its RF OUTPUT jack is
connected via a 75-ohm coax cable to the IRD RF INPUT. There is no power pass for LNB DC
power. (DC for the LNB is provided on the UTY4000 rear terminal strip and requires an
external DC power inserter. No DC voltage is applied to any F connector.) The input and
output RF connectors are Type-F jacks, and they are located on the option module rear panel.
