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.
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.

! 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. S1 S2 The ODW-720-F1 DIP-switches are pre-set from the factory, so that the unit can be used for point-to-point applications, togheter with an additional ODW-720-F1, straight out of the box, without the need for any type of user configuration.
Start up guide, point-to-point application Follow the steps below to get the unit up and running in a simple application. Master POWER COM +VA +VB COM Slave CH 1 TX RX POWER COM +VA +VB COM CH 1 TX RX …… Using the factory DIP-switch settings: …… Set DIP-switch S2:1 as desired. …… Connect The fibre link between the ODW-720-F1. …… Connect the power supply to both ODW-720-F1. …… After a few seconds the fibre link should be in operation, indicated by an active CH1 LED.
About the interfaces Power The power terminal has two independent inputs, +VA and +VB, allowing redundant power input. The ODW-720-F1 power supply is galvanically isolated from all other interfaces. Optical fibre interfaces ODW-720-F1 uses Small Form Factor Pluggable (SFP) transceivers. This means that a wide range of different fibre transceivers and connectors can be used (see page 12–13). RS-232 interface The RS-232 interface is a female 9-position D-sub.
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. CLICK! CLICK!
