3.3 D-422-MG-C3
Figure 4: D-422-MG-C3 Connector module
The D-422-MG also has a third alternative connector module: D-422-MG-C3. This module is
meant for Nevion FlashCase outside broadcast housing.
D-422-MG-C3 module use Molex KK connectors and interconnects with RJ45-KK included in
most FlashCase variants. D-422-MG-C3 is shown in figure 4. Note that this connector
module only occupies one slot in the sub-rack.
3.4 Mounting the connector modules
The details of how the connector modules are mounted, can be found in the user manual for
the sub-rack frame: FR-2RU-10-2.

To set up a link, two D-422 modules must be used. The RS-422 data cable is connected to
RS-422/E1 on each of the D-422 modules. The two modules are connected to the fibres with
one fiber from TX on module 1 to RX on module 2, and from RX on module 1 to TX on
module 2. The TX UPG connector contains an electrical version of the modulated signal
running on the fiber. This connector is used for future upgrade with a flashlink multichannel
DWDM system.
3.5 C1 RS-422 Connector Pin Assignments
RS-422 shall be connected to one of the RS-422 connectors, positioned as shown in figure
2. The connectors are RJ-45 style, 8-pin modular jacks. Each connector has two RS-422
ports, referred to as ports 1 and 2 in the below table. In the event that only one port is in use,
an RJ-11 style 4/6 (4-wire, 6-position) jack can be used instead. Signals marked as inputs on
the D-422-MG shall be connected to the outputs of the connected devices, and vice versa.
The columns for DB9 VTR Master and Slave show which pin on the 9 pin DSUB should be
connected to the signal. Note that when connecting an active device instead of a straight-
through cable between a VTR master and slave (device and controller), one end of the active
device must use a crossed cable. The table below takes the crossing on the slave side into
consideration.
