Safety
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.
Branch circuit protection (fuse) is required for this unit with rating not
exceeding 20 A.
Product should be connected to UL Listed power supplies rated 12 – 48 VDC,
min 500 mA or 24 VAC, min 500 mA or reliably grounded DC SELV source*.
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 fibre 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.

ODW-730 is a fibre optic modem that converts between electrical RS-485 and a fibre
optical link.
ODW-730 can also be used to convert from RS-485 to RS-232 by using a ODW-730 in
the same link as ODW-720.
Repeater – optical fibre links
ODW-730 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.

About the interfaces
Power terminal
The power terminal has two independent inputs, +VA and +VB, allowing redundancy
should either fail. The ODW-730 power supply is galvanically isolated from all other
internal electronics.
Optical fibre interfaces
ODW-730 uses Small From Factor Pluggable (SFP) transceivers that are in compliance
with the Multi-Sourcing Agreement (MSA). This means that a wide range of different fibre
tranceivers and connectors can be used.
RS-485 interface
A 4 position detachable screw terminal that can handle full duplex data rates up to
1.5 Mbit/s and can be set to either 2- or 4-wire RS-485 system.
When 4-wire RS-485 is selected, the terminals T/R+ and T/R– will always be set to
transmit and terminals R+ and R– will always receive data.
Manchester coded protocol can be tranferred with Synchroous mode.
Status port
The status port connects to an internal relay wich may be used to trigger an external
alarm if a fault condition occurs. During normal operation pins 1 and 2 are in contact
with each other, and pins 2 and 3 are isolated. During an optical link failure, or power
failure, pins 1 and 2 are isolated, and pins 2 and 3 are in contact with each other.
