Prepare the Fibre Optical Network
• Both units must be configured for point to point application by setting DIP-switch S2:2
to the ON position.
• 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 as shown in the
picture above.
• Connect the power supply to all units and verify that all fibre links become active. (CH
1 on both units are on, FL L off).
• Connect the LON devices to the corresponding LRW-702-F2 unit.
• The network is now up and running.
Point-to-Point Configuration
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.
