EPIM-C

B.5 EPIM-C

The EPIM-C supports thin coaxial cabling and is equipped with an internal Cabletron Systems TMS-3 Transceiver. Use the TERM switch on the front of the EPIM-C to set the internal 50 Ohm terminator. This eliminates the need to connect the port to a T-connector and terminator. Figure B-1 shows the setting for the terminator switch.

Internal Termination Switch

= On (internally terminated)

= Off (need external termination)

Connector Type

BNC receptacle, with gold center contact, for use with BNC type T-connectors and RG58 thin coaxial cable.

Grounding

Connecting a thin-net segment to earth ground at more than one point could produce dangerous ground currents.

The BNC port of the Coaxial Interface Modules is not connected to earth ground.
