Connection Possibilities
You can connect the Ethernet card in your TNC to your network
through a BNC connection (X26, coax cable 10Base2) or through the
RJ45 connection (X25, 10BaseT). You can only use one of the two
connections at one time. Both connections are metallically isolated
from the control electronics.
BNC connection X26 (coaxial cable 10Base2, see figure at upper
right)
The 10Base2 connection is also commonly known as Thin-Ethernet
or CheaperNet. For the 10Base2 cable you need a BNC-T connector
to connect the TNC to your network.
The distance between two T-connectors must be at least
0.5 meters (1.7 ft).
The number of T-connectors must not exceed 30.
Open ends of the bus must be provided with terminal
resistors of 50 ohms.
The maximum cable segment length, i.e., the distance
between two terminating resistors, is 185 m (600 ft). You
can connect up to 5 cable segments with each other via
signal amplifier (repeater).
RJ45 connection X25 (10BaseT, see figure at center right)
For a 10BaseT connection you need a Twisted Pair cable to connect
the TNC to your network.
For unshielded cable, the maximum cable length
between the TNC and a node is 100 meters (329 ft). For
shielded cable, it is 400 meters (1300 ft).
If you connect the TNC directly with a PC you must use a
transposed cable.
