Cable Pinouts C - 5
Also, since 802.3 AUI cables provide a ground shield isolated from the
signal and power pair's shields, these cables provide additional noise
immunity in noisy operating environments.
Cable Configuration Rules
Refer to the following configuration rules when configuring your network.
1. If the Bridge Module is to be connected to an IEEE 802.3 transceiver,
such as DEC's DESTA™, the transceiver cable must be IEEE 802.3
compliant.
2. If the Bridge Module is to be connected to a non-IEEE 802.3
transceiver, such as DEC's H4000™, the transceiver cable can be
either Ethernet V2.0 or IEEE 802.3 compliant.
3. IEEE 802.3 transceiver cables and Ethernet transceiver cables cannot
be interconnected.
4. A transceiver cable between an Bridge Module and a transceiver
cannot exceed 38 meters (125 feet). This accounts for the Bridge
Module internal cable equivalency of 2 meters (6.5 feet).
5. If you use office transceiver cable, it should not exceed the maximum
transceiver cable distance of 12 meters (39.4 feet).
6. If the configuration includes any other device with internal cabling
equivalency, subtract that amount from the 38-meter maximum. For
example, when connecting the Bridge Module to a configuration that
includes a DELNI, allow 5 meters of cabling equivalency loss for the
DELNI.
