Common Communication Link
5.3.1 Fiber Loop Modules
Two types of fiber optic modules are available to use to transmit and receive communication with the SK-NIC. See Figure 5.4. For more
information see SK-FML / SK-FSL installation sheet P/N LS10178-001SK-E.
SK-FSL Single-Mode Fiber
The SK-FML (Fiber-Optic Multi-Mode) and SK-FSL (Fiber-Optic Single-Mode) are plug-in fiber loop modules. The two types of fiber
optic modules are used as one channel to transmit or receive communications with the SK-NIC, ARCNET communication circuit.
The following describe the two types of fiber optic modules.
• The SK-FML is a fiber module that allows the multi-mode fiber to link between nodes.
• The SK-FSL is a fiber module that allows the single-mode fiber to link between nodes.
Each fiber loop module can Transmit (TX) and Receive (RX) fiber-optic cable connecting to the SK-NIC. Up to two fiber loop cards can
be added to the SK-NIC, and both cards may be combined in the same configuration. See Figure 5.5.

SK-NIC-KIT Mounting Kit

SK-NIC can be mounted within the 6808 cabinet or in the SK-NIC-KIT accessory cabinet. The SK-NIC-KIT includes the SK-NIC, cab-
inet with door, cable, & mounting hardware. The accessory kits are available if you want to install the SK-NIC outside of the 6808 cabi-
net.
5.3.2 SK-NIC Installation
The SK-NIC is designed to mount on one of the SLC standoff sets inside the cabinet or remotely using the SK-NIC-KIT.
Use the following steps to properly mount the SK-NIC inside the 6808.
1. Place the SK-NIC on one of the SLC standoff sets.
