EMM-E6 User’s Guide A-9
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).
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 50 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.
Internal Termination Switch
= On (internally terminated)
= Off (need external termination)
Connecting a thin coaxial cable segment to earth ground at
more than one point can produce dangerous ground currents.
