Functional description

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

To minimise the risk of interference, a shielded cable is recommended when the cable is located inside 3 m boundary to the rails and connected to this port. The cable shield should be properly connected (360°) to an earthing point within 1 m from this port. This earth-ing point should have a low impedance connection to the conductive enclosure of the apparatus cabinet, or similar, where the unit is built-in. This conductive enclosure should be connected to the earthing system of an installation and may be directly connected to the protective earth.

CAUTION

• ELECTROSTATIC DISCHARGE (ESD)
  Prevent electrostatic discharge damages to internal electronic parts by discharging your body to a grounding point (e.g. use a wrist strap).

For applications that only require half duplex communication it is recommended to use Y-mode. Please see the ODW-720 Management Guide for further details.

About the interfaces

Power
The power terminal has two independent inputs, +VA and +VB, allowing redundant power input.
The ODW-720-F2 power supply is galvanically isolated from all other interfaces.
Optical fibre interfaces
ODW-720-F2 uses Small Form Factor Pluggable (SFP) transceives. This means that a wide range of different fibre transceivers and connectors can be used.
RS-232 interface
The RS-232 interface is a female 9-position D-sub. Pin assignments are compliance with the EIA RS-232 standard.
Status port
The status port connects to an internal relay witch 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. Optical link failures can be classified in to two categories, local or remote, as indicated by the FL L and FL R LED’s. A local link failure is when an optical link is down at this particular unit. A remote link failure is when an optical link is down at some other unit. From the factory, the status port is set to trigger on both types of link failures. However, by setting DIP-switch S2:6 to the ON position, the status port will only trigger when a local link failure has occurred.

Mounting
This unit should be mounted on 35 mm DIN-rail, which is horizontally mounted inside an apparatus cabinet, or similar. Snap on mounting, see figure.

Cooling
This unit uses convection cooling. To avoid obstructing the air-flow around the unit, use the following spacing rules. Minimum spacing 25 mm (1.0 inch) above /below and 10 mm (0.4 inches) left /right the unit. Spacing is recommended for the use of unit in full operating temperature range and service life.

Removal
Press down the black support at the top of the unit. See figure.
