1 Product overview

1.1 General

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 Fabry­Perot 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 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.

3.2 D-422-MG-C2

Figure 3: D-422-MG-C2 Connector module

The D-422-MG also has an alternative connector module: D-422-MG-C2. This module is
mounted at the rear of the sub-rack. The module is shown in figure 3. Note that this
connector module only occupies one slot in the sub-rack.

D422-MG Rev. H

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.

This manual is available from our web site: http://www.nevion.com/
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 straight­through 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.

4 Remote control of Flashlink systems

For simplicity, this text refers to the card residing local to Multicon as the “local” card and the
one at the other end of the fiber as the “remote” card.

4.1 Requirements

Firmware revision 2.2.0 and FPGA revision 5 is needed on the card that sits local to Multicon
for this feature to work. Any firmware/FPGA revision will work for the card in the remote end.

One RS422 channel (out of 2, 4 or 8 depending on backplane type) needs to be available. It
must be the same channel for both cards, local and remote. The local card needs to be set
up through the debug interface of Multicon (or PC with RS422 and serial port software).

4.2 Cable wiring

The local card is connecting as a normal Flashlink card, talking to Multicon. But we use an
external cable to transmit data from Multicon directly to the fiber. Data from the fiber is
transmitted by the on-board MCU on the internal flashlink bus. Therefore, we only need 2
wires, RX+ of D422-MG is connected to RX+ of the flashlink frame, and likewise with RX-.

C3 and C1 backplane connections, local card

The remote card operates differently, here everything is done in the FPGA and both RX and
TX are done over the external connectors . This D422-MG repeats requests from Multicon to
the cards and responses from the cards to Multicon. Thus, for this end, RX of D422-MG
needs to be connected to TX of the flashlink frame, and TX connected to RX. Always make
sure + connects to + and - to -.

C3 and C1 backplane connections, remote card

nevion.com | 12

D422-MG Rev. H

4.3 Turning remote control on

First you need to find the right address of the card.
Below you can se the card is in frame 0 position 4 but the software always start with 0 so this

actually gives address 03. Valid addresses are 00 through 79.

Figure 6: Local card in rack 0, pos 4.

Under the CONFIG tab at the top of the Multicon web interface (login required with
administrative privileges, see Multicon manual for more info on this) there is an entry called

“Debug terminal”. This can be used to send commands directly to the card, bypassing the

web interface. The first command to use is a single question mark (in flashlink-terminology

called “hello”). In our example below we put in “03” for “Card” and “?” for “Command”, then
clicked “Ok”.

nevion.com | 13

D422-MG Rev. H

Figure 7:

The command “0319?” was then sent to the card, which responded with
1903D422-MG/1310nm,-7.5dBm

hw rev 1.0
sw rev 2.2.0
fpga rev 5
protocol ver 1.0

The command “remote” is used to enable or disable remote Flashlink control. To disable:
“remote 0”. To enable on port 1 use the command “remote 1”, and so on up to port 8. The

example above shows selecting port 1 for remote control. Below is shown the result, frame 5
was in our example sitting at the remote end of the D422-MG fiber link, and wired up
according to the previous chapter.

nevion.com | 14

D422-MG Rev. H

Figure 8:

Sending the command “remote conf” displays back which channel (if any) that is being used
for remote Flashlink control. The readback uses same format as the “remote” command
itself.

5 Operational status monitoring

The status of the module can be monitored in two ways.
GYDA system controller module.

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.

5.1 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.

5.2 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 9: 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.

6 Operation

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.
