•
The Arcnet bus will have two ends and both of these should be
terminated with a 100 Ohm resistor (
±
1%). The TT-3042D
does NOT contain any termination-resistor. If needed the ter-
mination resistor could be placed in the 15 pole SubD con-
nector connected to the twisted pair cable. This is the case for
the accompanying cable.
•
Always use shielded twisted pair cables and shielded con-
nectors (otherwise the EMC specifications are not guarantied
to be fulfilled).
•
The length of the cable making up the Arcnet bus should be
no longer than 100 meters.
•
Minimum spacing between devices connected to the Arcnet
bus is 2 meter of cable.
•
No more than 8 Arcnet devices (including transceiver) must
be connected to the Arcnet bus.
