Overview
The goal of zero-latency roaming is to allow clients to seamlessly
maintain their communications as they move from one access point to
another. The advanced Moxa Wireless Access Controller, the WAC-2004,
together with Controller-based Turbo Roaming technology, enables
millisecond-level roaming over different IP subnets. The advanced
roaming algorithm along with Mobile IP technology allows wireless clients
to roam between APs in different IP subnets within milliseconds while
upholding stringent security in extremely demanding environments. The
WAC-2004 is rated to operate at temperatures of 0 to 50°C and is rugged
enough for on-site installation in any harsh industrial environment.

Installation and Configuration
Before installing the WAC-2004, verify that all items in the Package
Checklist are in the box.
Note that the WAC-2004 must be configured before use. Refer to the
WAC-2004 Series User’s Manual for more details.
The WAC-2004 has a default IP address of 192.168.127.253, which you
must use when connecting to the device via LAN 1 (LAN 2-4 are reserved
for future expansion) for the first time. When configuring the WAC-2004
for the first time, use the following default user name and password:
User name: admin
Password: root

Grounding the WAC-2004
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground wire from the ground
screw on the rear side (shown below) to the grounding surface prior to
connecting devices.
This product is to be mounted to a well
surface, such as a metal panel.
Connecting the Power Inputs
The WAC-2004 supports dual redundant power supplies: Power Supply 1
(PWR1) and Power Supply 2 (PWR2). The connections for PWR1 and
PWR2 are located on the rear side (shown below). Be sure to use a
standard power cord with an IEC C13 connector, which is compatible with
the AC power inlet.
Pin Assignments
Gigabit Ethernet Port Connection
The WAC-2004 offers 1 gigabit Ethernet connector (LAN 1) and 3
reserved Ethernet connectors (LAN 2-4) for future expansion. When the
cable is properly connected, the LEDs on the RJ45 connectors will glow to
indicate a proper connection.
1000 Mbps (Gigabit) Ethernet mode
Not operating or 10 Mbps Ethernet mode

The pin numbers for the 8-pin RJ45 connectors (and ports) are
typically not labeled on the connector (or port). Refer to the
diagram above to see how the RJ45’s pins are numbered.
Serial Console Connection
The WAC-2004 offers one serial port with DB9 male connector for its
console access. The pin assignments are shown in the following table:
The pin numbers for the male DB9 connectors, and hole numbers
for the female DB9 connectors are labeled on the connector.
However, the numbers are typically very small, so you may need
to use a magnifying glass to see the numbers clearly.
