1General
Figure 1 D-422-MG Block diagram
The flashlink D-422-MG module provides an economical solution for transmitting RS-422
and GPI data signals via fiber optic cable. A pair of D-422-MG allows bi-directional
transmission of up to 8 RS-422 and 16 GPI data lines for distances over 60km. When
access to fiber is limited, D-422-MG can be combined with the flashlink optical
multiplexing WDM, CWDM or DWDM products.
The D-422-MG module multiplexes up to 8 RS-422 and 16 GPI inputs into an outgoing
datastream while at the same time demultiplexing an incoming datastream into 8 RS-422
and 16 GPI outputs. The outgoing multiplexed stream is available both as an optical
signal and as an electrical signal for use with a flashlink multichannel DWDM system.
As stand alone unit, the D-422-MG module utilises 2 fiber strands for bi-directional data
transport. Using either 2 fiber strands or optical multiplexing technology guarantees
minimum possible latency for applications where timing is crucial. The D-422-MG module
is supplied together with the D-422-MG-C1 connector module. The optical output is
made with a Fabry-Perot laser diode for 1310±40nm or a DFB laser for 1550±40nm and
the CWDM wavelengths according to ITU-T G.694 from 1470±6nm up to 1610±6nm.
The product is available in 19 versions:
D-422-MG-13T -7.5dBm 1310±40nm -7.5 dBm F-P laser
D-422-MG-13T 0 dBm 1310±40nm 0 dBm F-P laser

3Connector module
3.1 D-422-MG-C1
Figure 2 D-422-MG-C1 Connector module.
The D-422-MG has a dedicated connector module: D-422-MG-C1. This module is
mounted at the rear of the sub-rack. The module is shown in figure 2. Note that this
connector module always occupies two (2) slots in the sub-rack.
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.
3.2 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.

3.3 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.

Figure 3 RS-422 outlet
3.4 GPI Input Connector Pin Assignments
GPI inputs shall be connected to the DB25 connector marked “GPI
IN”. The pinout is the same as for the VikinX GPI panels, see table.
All inputs are internally connected to +5V via a pull-up resistor. The
inputs will be activated when pulling them to Ground.
Ground is available on the following pins: 2, 5, 8, 11, 13, 16, 19, 22,
25 and on the connector chassis.

3.5 GPI Output Connector Pin Assignments
GPI outputs shall be connected to the DB25 connector marked
“GPI OUT”. The pinout is the same as for the VikinX GPI panels,
see table.
The GPI outputs are of open collector type. An output can
switch a maximum load of 100mA at 30V.
Any device to be controlled by the GPI outputs (lamp, LED or
similar) needs to be connected to an external supply voltage on
one end and to the GPI output on the other end.
Ground is available on the following pins: 2, 5, 8, 11, 13, 16,
19, 22, 25 and on the connector chassis.
