NOTE: It is important that those pins labeled "No connection" be left un-terminated. Connection of
these pins may damage the ACC2500 or AMI and may not be covered under warranty.
To facilitate the connection of these two ports to the AMI, the 69612-xxx (purchased separately) contains
three modular connectors and two cables. The two cables included combine the 8-pin and 6-pin ports as
necessary to allow connection to the front AMI control port using a standard category-5 networking cable.
This CAT-5 cable must be provided by the installer and must not exceed 45 feet in length.
