The Transceiver Module can transmit
and receive Ethernet 10 Mbit/sec
traffic over thin Ethernet cable. The
Transceiver Module features
switchable internal/external coaxial
termination, Jabber protection and
selectable SQE Test.
The Transceiver Module is used to
provide an extra port or connectivity
to thin Ethernet on the following
LinkBuilder products:
•
ECS modules (3C12076,
3C12050/1)
•
MSH modules (3C18110, 3C18120,
3C18124 and 3C18146)
•
FMS Stackable Hubs (3C16250,
3C16265, 3C16271 and 3C16371)
•
FMS II Stackable Hubs (3C16670
and 3C16671)
Repeaters (3C16170, 3C16200, 3C16210
and 3C16505)
This product has the benefit of a
"lifetime warranty", details of which

Setting up the Module
Segment Termination
The thin Ethernet cable may be
connected to the Transceiver Module
in one of two ways – externally
terminated or internally terminated.
External termination uses a T-piece
adapter, with terminator fitted,
between the cable and the module. An
in-line terminated adapter may be
used if you prefer. Move SWITCH 1
(Figure 2) to the ‘EXT’ position.
With internal termination,
the cable is connected
directly to the BNC socket,
and the termination
selector (SWITCH 1 in
Figure 2) moved to the
‘INT’ position.
Access to the slide switch
is through a slot in the
metal mounting panel of
the Transceiver Module,
where the positions are
labelled.
The modules are shipped with
SWITCH 1 set for internal termination.
Ensure that SWITCH 1 is selecting the
termination mode you require.
