2. Connect and configure the LAN and Com Bus for the Broadlinx board
(NR-33000 NIC/Sync/OPM board).
• These Configuration steps are covered in the specific control sys-
tems.
The Broadlinx software can be configured to monitor router outputs
that are feeding critical downstream equipment (such as a transmitter)
for Protected path operations. If the Primary output signal is inter-
rupted, the system will automatically select the Secondary output that
is carrying the same signal and then trigger a system alarm. For wiring
information, see
Figure 54 on page 96 . For Protected path configuration
instructions, see Protected Paths on page 345 .
The Broadlinx board is equipped with a plug-in, rechargeable lithium-
ion battery that is used to back up the Routing switcher status for
Encore-controlled systems. This battery is rated for approximately 500
power cycles. If there is a power failure and the battery fails to provide
power, the Broadlinx board will need to obtain the router status from
the Encore System Control Module (this data will be sent automati-
cally). For the location of this battery, see
Figure 88 on page 174 .
• An extensive set of gain, phase, filtering, and other adjustments are
available for each signal if the router is equipped with the VI-33100
“universal” input boards, and analog signals are received. For more
information about the VI-33100 input board, please refer to
Section 6-
Analog Input Processing on page 375 .

If output monitoring is required, refer to Output Monitoring on page 200 .
4. Check the Frame number switches on multi-frame systems. See Frame
Number Settings on page 212 .
Optional Connections
1. Connect the rear panel ALARM BNC to the facility alarm system (This
step is optional). The alarm port operates according to the SMPTE
standard 269M-1999.
For an overview of the alarm system, see the Alarm System section on
page 67.
The rear panel Alarm BNC can be configured to report primary alarms.
TRX-NXT-256x256/33256 configuration is via a jumper on the NR/SR-
33000 board, as shown on
Figure 88 on page 174 and Figure 89 on
page 175 . TRX-NXT-512x512 configuration is via a jumper on the RP-
33500 512 x 512 Rear Panel board as shown on Figure 94 on page 179 .
TRX-NXT-256x512 configuration.
For the TRX-NXT-128x256, the configuration is through a jumper on the
NR/SR-33000 board, which is shown in
Figure 88 on page 174 and
Figure 89 on page 175 .
