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 5: 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. -

Page 8: Functional Description
OCP Over Current Protection Converter serial interface – optical fibre ODW-630-F1 is a fibre optic modem that converts between electrical RS-485 and a fibre optic link. ODW-630-F1 can also be used to convert from RS-232 to RS-485 by using one ODW-620-F1 and one ODW-630-F1. - Page 9 Point-to-point communication via fibre optical network The serial data is transferred via a fibre optic network between two ODW-630-F1s. This application is useful e.g. for long distance communication, where electromagnetic interference may occur or when isolation of the electrical network is needed. The maxi- mum optical fibre distance between two units depends on selected fibre transceiver and fibre type.
- Page 10 Manchester coded protocol can be transferred with synchronous mode. Redundant power supply, galvanic isolated (2 kVAC) to other ports The ODW-630-F1 should be supplied with safety extra low voltage (SELV). It is designed to operate permanently over a wide DC or AC voltage input range and provided with two independent inputs for enhanced redundancy if either supply fails.
- Page 11 System delay in an optical network Serial data transferred from one ODW-630-F1 via an optical network to a second one, will be delayed due to the length of optical fibre and the signal processing within the units. The signal processing delay is dependent on the data rate and conversions, and the fibre delay is dependent on the total length of the optical fibre.

The worst-case optical power budget (OPB) in dB for a fibre-optic link is determined by the differ- ence between the transmitter’s output optical power (min) and the receiver input sensitivity (max).
