EPIM-C

EPIM-C

The EPIM-C supports thin-net coaxial cabling and is equipped with an internal Cabletron Systems TMS-3™ Transceiver. You can 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 tee-connector and terminator. Figure A-4 shows the setting for the terminator switch.

The link distance is up to 185 meters on the thin-net coaxial cables.

Connector Type

This connector type is a BNC receptacle, with gold center contact, for use with BNC type tee-connectors and RG-58 thin-net cable.

Grounding

For safety reasons, only one end of a thin-net segment should be connected to earth ground. Connection to earth ground at more than one point on the segment may cause dangerous ground currents.

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

EPIM-A and EPIM-X (AUI Port)

The EPIM-A is a DB-15 female connector used to attach segments to an external transceiver. The EPIM-X is equipped with dual internal transceivers. It has a DB15 male connector used to attach segments to an AUI cable. Figure A-5 shows both modules.
