The WACI NX has two 10/100 Auto MDX Ethernet ports. They are also POE (power over Ethernet)
capable with the NX-POE add-on module. The Auto MDX allows the use of null or straight through
LAN cables to the ports.
LAN Port
The WACI may be connected to a network using a standard RJ-45 Ethernet cable in this port. Both 10Mb
and 100Mb connections are supported.

The Relays on the WACI NX+ have two connection types: N.O. = Normally Open, and N.C. = Normally
Closed. The “Normal” position is the state of the relay when it is not turned on (not energized). You can
turn the relays on and off using the relay diagnostic page (see Relay Diagnostics, page
51
), using an
Event Manager “Relay Action” (see
Relay
, page
73
), or through an RPC method call (see Relay Methods
(WACI NX+ Only), page
116
). The Relay ports are available on the WACI NX+ only.
Relay Ports 1-4
Each port consists of 3 lines: NO (Normally Open), CP (Center Pole), NC (Normally Closed). Connect
the incoming wire to the CP connection, and the outgoing wire to either of the other two ports (NO or
NC). The outgoing port you choose depends on which type of connection you wish to consider “Normal”.
