Cabling the ERX System
Cabling I/O Modules
The following sections describe how to cable I/O modules with different types of connectors. For information about the connectors on the different line modules, see Appendix B, Module Specifications.
Cabling BNC Connectors
To cable I/O modules with BNC connectors:
1Insert the RX male BNC connector into the selected port.
2Terminate the other end in the appropriate network interface, such as a multiplexer (MUX) device.
