4.1.5 Connecting an AUI Cable to an EPIM-A
Connect an EPIM-A to an external network segment as follows:
1. Attach an external transceiver to the network segment that will be
connected to the AUI port. Refer to the applicable transceiver manual.
2. Attach an AUI cable, no longer than 50 meters in length, to the
transceiver connected to the network in step 1.
3. Connect the AUI cable to the EPIM-A. (See Figure 4-5.)
4. Lock the AUI connector into place using the connector slide latch.
Figure 4-5. The EPIM-A
Ensure that the Signal Quality Error (SQE or “heartbeat”)
test function is disabled on the external transceiver connected
to the SEH. The SEH will not operate and the network will be
unusable if the transceiver has the SQE test function enabled.
Refer to the applicable transceiver manual.
