CONNECTING TO THE NETWORK

4.1.6Connecting an AUI Cable to an EPIM-A

Caution: Ensure that the external transceiver to which the SEHI will be connected does not have the signal quality error (SQE or “heartbeat”) test function enabled. The SEHI will not operate if the transceiver has the SQE test function enabled, and the network will be unusable. Refer to the applicable transceiver manual.

To connect an EPIM-A to an external network segment:

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 AUI port located on the EPIM-A. See Figure 4-6.

4.Lock the AUI connector into place using the connector slide latch.
