• Connect the fibre pairs between the units. Always connect CH 1 from one unit to CH

2 on the next unit as shown in the picture above.

• Connect the power supply to all units and verify that all fibre links become active.

(CH 1 and CH 2 LED’s are on, FL L and FL R LED’s are off).

• Connect the communication devices to the corresponding ODW-720 unit.
• The network is now up and running.
Note: In an ODW-720 fibre optic network there will be some additional processing
delays that do not exist in an electrical bus. It is possible that the application must be
adjusted to accommodate these delays if using many ODW-720 units in a large network.
See page 31 “Calculating system processing delay” for more information on how to
determine the overall system delay time.
