NOTE: Cabletron Systems reserves the right to change these
specifications at any time without notice.
BNC INTERFACE (Ports 1-12)
Type: BNC receptacle, with gold center contact,
for use with BNC type plugs and RG-58
thin-net cable.
Internal Transceiver: Cabletron Systems TMS-3 Transceiver.
For further information, refer to the
TMS-3 Transceiver User's Manual.
Terminations: Each segment is internally connected to a
50 ohm terminator in the port.
Grounding: Each segment connector shield is
internally connected to earth ground by the
THN-MIM. This eliminates the need for
grounding the segments connected to the
BNC ports.
INDICATORS
POK Indicates that the port is connected to the
network.
When the module is first installed into the
MMAC, the LED will not be lit until the
first data packet passes through the port.
RCV Indicates that the module is receiving a
data packet from that segment.
ENVIRONMENTAL REQUIREMENTS
