Installing Network Cable

10BASE-T Requirements

STRAIGHT-THROUGH/CROSSOVER CABLE/CONNECTOR

NOTE: The 10BASE-T cable and RJ-45 jacks for hub to terminal device connections must be configured as straight through. The 10BASE-T cable and RJ-45 jacks for hub to hub connections must be configured as crossover.

The “X” port provided on the LANMaster T8 changes a physical straight through cable configuration to a logical crossover cable configuration for hub to hub connections.

Therefore, ensure that all 10BASE-T cable to be installed is straight- through:

Installing Thinnet 10BASE-2 Cable

The LANMaster T8 has a female BNC MDI connector installed at the back for connection to 10BASE-2 cable and comes with a mating T- connector and a 50-ohm segment terminator for making the cable connection.

To connect to 10BASE-2 network cable:

1.Locate or build IEEE 802.3 compliant 10BASE-2 cable with male BNC connectors installed at both ends.

2.Install the mating T-connector to the female BNC connector on the LANMaster T8.

3.Install 10BASE-2 cable to one side of the T-connector.

4.Install 10BASE-2 cable to other side of the T-connector

OR, if the LANMaster T8 is the last network device in the daisy chain, install a 50-ohm terminator.

5.Verify that the 10BASE-2 segment coax cable segment is terminated properly at both ends.

The two active pairs in a 10BASE-T network are pins 1 & 2 and pins 3 & 6. Use only dedicated wire pairs (such as blue/white & white/blue, orange/white & white/orange) for the active pins.
