4.2.1
Ethernet network
Dual On-Board ETHERNET 10/100/1000 Base T connection is standard on the Honeywell Configured
HP Z4 G4 platform.
4.2.2
Local Control Network
The connection to the LCN Network is made via the LCNP4E2 mid-size Local Control Network
Processor card model no. TP-LCNP05. This card provides the communication path for the Honeywell
Configured HP Z4 G4 to other LCN modules. The LCNP4E2 consists of a PCI Express 3.3 Volt
LCNP4E2 full height and half-length Size card, a MAU cable and the LCN MAU (Media Access Unit)..
The LCN node address should be set to the address the customer requires. If the LCN address is not
known, then the node address should 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 live node in a
customer's network segment. This is consistent with the current LCN standard procedure. The following
model numbers are available for the Local Control Network Processors:
TP-LCNP05
4.2.3
LCN connections
The LCN Cable A and Cable B connections are made through a single cable from the LCNP4e2 board
to the LCN Media Access Unit (MAU) contained in a metal housing. The following illustrates a LCN
MAU to LCN cabling.
4.2.4
MAU connection
Connect the MAU to both Cable A and Cable B coax T-connector as illustrated in the following Figure.
