must be set to the address the customer wants. If the LCN address is not known then the node address
must be set to zero (0). Setting the address to zero (0) allows the node to be connected to the LCN
without the risk of an address conflict with some other node. This is consistent with the current LCN
standard procedure. The Honeywell server platform uses only a digital system clock. When the HP
ProLiant DL360p Gen8 server platform is added to an existing system that contains nodes running
analog clocks that system must have at least two (2) KxLCN boards for analog/digital clock translation.
The model number for the LCNP4e is TP-LCNP04 (with Honeywell part number 51405098-100) and for
the LCNp4e2 is TP-LCNP05 (with Honeywell part number 51454493-126).

LCN cables
The two LCN cables and with T-connectors (and terminators, if applicable) are routed vertically inside
the left rear corner of the cabinet (when viewed from the rear door) near the vertical cable duct where
the connection is made to the LCN MAU. The cable between the LCNP4e/LCNp4e2 board and the LCN
MAU is 2 meters in length.
4.2.4
LCN connections
The LCN Cable A and Cable B connections are made through a single cable from the
LCNP4e/LCNp4e2 board to the LCN Media Access Unit (MAU) contained in a metal housing. The
following illustrates a LCN MAU to LCN cabling.

MAU connection
Connect the MAU to both Cable A and Cable B coax T-connector as illustrated in the following Figure.
