Before installation:
Read this manual completely and gather all information on the unit. Make sure
that you understand it fully. Check that your application does not exceed the safe
operating specifications for this unit.
This unit should only be installed by qualified personnel.
This unit should be built-in to an apparatus cabinet, or similar, where access is
restricted to service personnel only.
The power supply wiring must be sufficiently fused, and if necessary it must be
possible to disconnect manually from the power supply. Ensure compliance to
national installation regulations.
This unit uses convection cooling. To avoid obstructing the airflow around the unit,
follow the spacing recommendations (see Cooling section).
Before mounting, using or removing this unit:
Prevent access to hazardous voltages by disconnecting the unit from the power
supply.
Warning! Do not open a connected unit. Hazardous voltages may occur within
this unit when connected to a power supply.
Class 1 Laser Product
This unit is designed to meet the Class 1 Laser regulations. However, the user is
warned not to look directly into fibre optical port or any connected fibre.
Care recommendations
Follow the care recommendations below to maintain full operation of the unit and to
fulfil the warranty obligations.
This unit must not be operated with covers or lids removed.
Do not attempt to disassemble the unit. There are no user serviceable parts inside.
Do not drop, knock or shake the unit. Rough handling beyond the specification may cause
damage to internal circuit boards.
Do not use harsh chemicals, cleaning solvents or strong detergents to clean the unit.
Do not paint the unit. Paint can clog the unit and prevent proper operation.
Do not expose the unit to any kind of liquids (rain, beverages, etc).
The unit is not waterproof. Keep the unit within the specified humidity levels.
Do not use or store the unit in dusty, dirty areas. Connectors as well as other
mechanical parts may be damaged.
If the unit is not working properly, contact the place of purchase, nearest Westermo
distributor office, or Westermo Tech support.
Fibre connectors are supplied with plugs to avoid contamination inside the optical port.
The plug should be fitted when no optical fibre is inserted in the connector, e.g. during
storage, service or transportation.

Note. Fibre Optic Handling
Fibre optic equipment requires careful handling as the fibre components are very
sensitive to dust and dirt. If the fibre is disconnected from the modem, the protective
plug on the transmitter/receiver must be replaced. The protective plug must be kept on
during transportation. The fibre optic cable must also be protected in the same way.
If this recommendation is not followed, it can jeopardise the warranty.
Cleaning of the optical connectors
In the event of contamination, the optical connectors should be cleaned by using forced
nitrogen and some kind of cleaning stick.
Recommended cleaning fluids:
• Methyl-, ethyl-, isopropyl- or isobutyl-alcohol
• Hexane
• Naphtha
Maintenance
No maintenance is required, as long as the unit is used as intended within the specified
conditions.

Description
This ODW-622 is a fibre optic modem used for redundant ring and multidrop applications. It acts as a converter between a serial port and a fibre optical link. The maximum
distance of the fibre link depends on selected transceiver and fibre type. Distance up to
80 km (50 miles) is available.
The ODW-622 is designed for harsh out-door usage, in industrial, road or railway
installations.
Data will be sent transparently over the fibre optical link via the serial interface RS-232.

Converter serial interface – optical fibre
ODW-622 is a fibre optic modem that converts between electrical RS-232 and a fibre
optical link.
ODW-622 can also be used to convert from RS-232 to RS-485 by using a
ODW-622 in the same link as ODW-632.
Repeater – optical fibre links
ODW-622 is a fibre optic repeater that repeats received data from one fibre link out to
the other link. This is useful e.g. for long distance communication, where electromagnetic
interference may occur or when isolation of the electrical network is needed. The maximum optical fibre distance depends on selected fibre transceiver and fibre type. Distances
up to 80 km (50 miles) are available.

PLC PLC
ODW-622 converts data using rates from 300 bit/s up to 250 kbit/s. Retiming of the data
ensures that the correct signal form is transmitted from the ODW-622 converter.
Designed for harsh environments, such as industrial, road and railway
applications
ODW-622 complies with standards for industrial environments and railway signalling and
telecommunications apparatus. Additionally, the wide climatic range of the ODW-622
allows it to be installed in out-door cabinets without any additional measures, such as
heating, etc.
Redundant ring via fibre optical network
Under normal operation the serial data is sent over ring A. Should a fault be detected on
the fibre ring then the data will be carried on rings A and B.

Ring B Ring B Ring B

Note! Ring A start up at TX (channel 1) and ring B ends up at RX (channel 1).
… Normal operation, data exchange between serial master and slave.
• ODW-622 unit connected to the PLC master receives serial data at the electrical
port, it converts and transfers this master frame via the fibre ring A. At this unit, the
repeating of transferred frames is stopped until this transferred master frame has
returned via ring A.
This master frame will be repeated through fibre ring A by all the other units. Each
of these units will also convert the master frame to serial data and send it via the
electrical port.
• ODW-622 unit, to which the addressed Slave is connected, receives serial data from
the Slave. This unit converts slave data and transfers the slave frame via ring A.
The repeating of transferred frames is stopped until this transferred slave frame has
returned via ring A.
