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.
This manual is available from our web site: http://www.network-electronics.com/

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.

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.

4Operational status monitoring
The status of the module can be monitored in two ways.
1. GYDA system controller module.
2. LED’s at the front of the sub-rack.
The LED’s are mounted on the module itself, whereas the GYDA-SC controller is a
separate flashlink module which presents the status of the flashlink modules in the
frame(s) as a web site.
The functions of the two monitoring systems are described below.
4.1 GYDA – Monitoring and control
From within GYDA it is possible to have alarms on loss of signal, loss of reclocker lock,
voltages, laser failure etc. As of firmware version 2.0.0 of D-422-MG it is also possible to
have alarms on each of the 16 GPI inputs, as well as the 16 GPI outputs. Only the GPI
inputs have alarms attached to them by default. Also, the same firmware version enables
control of the GPI outputs, so each output can follow remote input, drive active low or set
high impedance. All these functions are available from both web and SNMP. This means
that spare GPI inputs and outputs on D-422-MG can be used to extend GYDA with more
inputs and outputs.
4.2 Front Panel - Status Monitoring
The status of the module can be easily monitored visually by the LED’s at the front of the
module. The LED’s are visible through the front panel as shown in the figure below.
Figure 4 LED overview of D-422-MG
(Text not printed on the front panel).The D-422-MG has 3 LED’s. The colours of each of
the LED’s have different meanings as shown in the table below.

5Operational status monitoring
Guidelines to limit hazards from laser exposure.
All the available EO units in the flashlink®range include a laser.
Therefore this note on laser safety should be read thoroughly.
The lasers emit light at wavelengths around 1310 nm or 1550 nm. This means that the
human eye cannot see the beam, and the blink reflex cannot protect the eye. (The
human eye can see light between 400 nm to 700 nm).
A laser beam can be harmful to the human eye (depending on laser power and exposure
time). Therefore:
!! BE CAREFUL WHEN CONNECTING / DISCONNECTING FIBER PIGTAILS (ENDS).
NEVER LOOK DIRECTLY INTO THE PIGTAIL OF THE LASER/FIBER.
NEVER USE MICROSCOPES, MAGNIFYING GLASSES OR EYE LOUPES TO LOOK
INTO A FIBER END.
USE LASER SAFETY GOGGLES BLOCKING LIGHT AT 1310 nm AND AT 1550 nm
Instruments exist to verify light output power: Power meters, IR-cards etc.
flashlink®features:
All the laser module cards in the flashlink®product range, are Class 1 laser products
according to IEC 825-1 1993, and class I according to 21 CFR 1040.10 when used in
normal operation.
More details can be found in the user manual for the FR-2RU-10-2 frame.
Maximum output power*: 5 mW.
Operating wavelengths: > 1270 nm.
*Max power is for safety analysis only and does not represent device performance.
