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.

Connector Type
BNC receptacle, with gold center contact, for use with BNC type
T-connectors and RG58 thin coaxial cable.
Grounding
The BNC port of the Coaxial Interface Modules is not connected to earth
ground.
Connecting a thin-net segment to earth ground at more than
one point could produce dangerous ground currents.
Internal Termination Switch
= On (internally terminated)
= Off (need external termination)
