Cabletron Systems EMM-E6 Ethernet manual EPIM-C BNC Port, Thin-net cable Figure A-5

A.11 EPIM-C (BNC PORT)

Internal Transceiver:	Cabletron Systems TMS-3
	Transceiver
Type:	BNC receptacle, with gold
	center contact, for use with BNC
	type T-connectors and RG-58
	thin-net cable (Figure A-5).

Internal Termination Switch

= On (internally terminated)

= Off (need external termination)

Figure A-5. EPIM-C (with BNC Port)

Termination:	Using the switch to the side of
	the port, you can internally
	terminate the port on the module
	via a built-in 50Ω terminator.
	This eliminates the need to
	connect the port to a T-connector
	and terminator.
Grounding:	For safety, connect only one end
	of a thin-net segment to earth
	ground. Do not connect the BNC
	port of an EPIM-C to earth
	ground.

Connecting a thin coaxial cable segment to earth ground at more than one point can produce dangerous ground currents.
