3.4TRANSCEIVER REQUIREMENTS

When connecting an external network segment through a transceiver to the SEHI with an EPIM-A, the following requirements must be met:

•The transceiver or Ethernet device to which the module is connected must meet IEEE 802.3 standards, and/or Ethernet Version 1.0 or Version 2.0 standards.

•The Signal Quality Error (SQE) test function on the transceiver must be disabled when it is connected to a repeater or to an Ethernet Version 1.0 device. In addition, some Version 2.0 equipment does not support the SQE test. Devices that do not support the SQE test interpret the SQE test pulse as a collision.
