FOM-2000-UM Single-Mode or Multi- Mode Fiber Module Add the FOM-2000-UM to the FNC-2000 network interface controller to allow the use of single-mode or multi-mode fibers in a FleX-Net™ or MMX™ network. Plug-in optical modules allow for cost-effective network configurations made of fiber only or a mix of wires, single- mode fibers and multi-mode fibers.
Side A Connect to P10 on the FNC-2000 Figure 1 FOM-2000-UM connections, LEDs, and jumpers Connections for Optical Modules There are 2 bays for optical modules. L1 corresponds to Side A in the FleX-Net™ or MMX™ network. L2 corresponds to Side B.
End cap Figure 2 Optical module lever and end cap 1. Insert the module into one of the metal bays on the FOM-2000-UM. The lever must be closed as shown in Figure 3. The module should slide in easily. Figure 3...

3. To protect the module from dust, leave the end cap on until the fiber cable is connected to the board. Figure 5 Optical module in FOM-2000-UM with end cap To remove an optical module 1. Remove the end cap.
2. Install the supplied spacers on the two bottom mounting holes of the FNC-2000 network controller. 3. Connect the FOM-2000-UM to connector P10 on the FNC-2000. 4. Install the FOM-2000-UM on the spacers with the optical module bays facing out as shown in Figure 7. 5. Remove the protective cap from the optical module.
Wiring Wire from L1 to L2 A maximum of 63 nodes can be connected. Always connect L1 to L2 on the next node, and always connect TX to RX on the next node, as shown in Figure 8. Attention: Do not connect L1 to L1, or L2 to L2. If you do, the network might not function correctly.
See Figure 11. • On nodes with mixed connections, only one optical module is used. Remove the jumper corresponding to the unused bay on the FOM-2000-UM. • See LT-6014, the FNC-2000 Installation Instructions, for more information on installing and wiring the FNC-2000.
