Page 3: Before Installation
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. -
Page 4: Maintenance
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. -

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.

Page 8: Functional Description
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. - Page 9 Data rate up to 250 kbit/s 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...
- Page 10 • When the “first” ODW-622 unit receives the master frame (the same frame that has been transmitted by this unit), or after a timeout, data conversion will be allowed again. The received slave frame will be converted and transmitted at the electrical port.
- Page 11 The data is transferred via the fibre optic network to the serial ports of all units. If ODW-622 is connected to two optical fibre links (mid unit) converted data will be trans- mitted in both directions, via both CH 1 and CH 2. With only one optical fibre link (end unit) converted data will be transmitted in one direction, via CH 1 only.

The data carrier detect DCD signal is set as long as the fibre link is in operation, ready to transfer data. The data set ready DSR signal is set as long as the ODW-622 is in service. If RTS/CTS is set to OFF will CTS always be set to active. - Page 13 • The data exchange between a master and slave via ODW-622 fibre optic link will run from the ODW-622 units connected to a master to the slave and the same way back to the master. The system delay is calculated by summing the following: 1.

Configuration All needed configurations and parameter settings are done by the DIP-switches, located under the top lid of the ODW-622. DIP-switch settings Before DIP-switch settings: Prevent damage to internal electronics from electrostatic discharges (ESD) by discharging your body to a grounding point (e.g. use of wrist strap) Note: Disconnect power before DIP-switch settings. -
