SERCOS connector on the ControlLogix module/SoftLogix PCI 
Card and thread the connector on finger tight.
3. Insert one end of another fiber-optic cable into the Transmit 
SERCOS connector on the last 1394 system module in the ring and 
thread the connector on finger tight.
4. Insert the other end of the cable (from step 3) into the Receive 
SERCOS connector on the ControlLogix module/SoftLogix PCI
