Unison CE CMEd won't bind to stations repair

This repair is under the assumption that the problem is hardware related and (LON) voltages are good.


  1. The culprit is almost always the ULP transceiver U8 on the arch card (ETC part # Z623-F).
  2. In rare cases, U7 (Z9032) and L4 (L9022-F) on the arch card are bad, as well.
