Multidrop Configuration
Prepare the Fibre Optical Network
• The first and last LRW-702-F2 units must be configured as Multidrop end units by
settting DIP-switch S2:2 to the ON position. (End units only have one fibre pair each and
must know that this is a fact)
• Set DIP-switch and S2:1 as desired. See page with “Status port” for more information.
• Verify that DIP-switch S2:3 is in the OFF position.
• 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 LEDs are on, FL L and FL R LEDs are off).
• Connect the LON devices to the corresponding LRW-702-F2 unit.
• The network is now up and running.
PROCESSING DELAYS
In an LRW-70-F2 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 LRW-702-F2 units in a large network.
See page with “Calculating system delay” for more information on
how to determine the overall system delay time.
