Causes of Fault Transceiver Cables
The following list describes causes of faulty trans-
ceiver cables:
Improper Grounding (pin 1 vs. pin 4).
Bad ground:
Shell connector not crimped onto AUI
cable braid.
Ribbon cables in computers not shielded
or improperly mounted.
Broken pair wires or unseated AUI connec-
tor pin.
Improper pairing - Verify that signal and
power wires are paired (for example,
Transmit + paired with Transmit -)
Individual pairs not individually shielded (for
example, Ethernet V1.0 type cable).
