1. Introduction
The WAC-2004A is Moxa’s high-end Wireless Access Controller that incorporates with the TAP-213 Series,
TAP-323 Series, and AWK 3131A-RTG (Rail Train to Ground) Series and is designed specifically for
Railway applications. The WAC-2004A supports not only single-subnet roaming (Layer 2), but also allows
roaming between multiple subnets (Layer 3) with Mobile IP technology.

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, WAC-2004A,
together with controller-based Turbo Roaming technology, enables millisecond-level roaming over
multiple 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-2004A is rated to operate at temperatures of 0 to 50°C and
is rugged enough for on-site installation in any harsh industrial environment.

WAC-2004A Introduction
1-5
The WAC-2004A offers one pair of Gigabit Ethernet ports with the port binding feature enabled (LAN 1 and
LAN 2) for Ethernet failover redundancy. When the cable is properly connected, the LED on the front panel
will glow to indicate a proper connection.
See below for detailed pin assignment and LED indication:
Pin 10/100 Mbps 1000 Mbps

ETx+
TRD(0)+
2 ETx- TRD(0)-
3 ERx+ TRD(1)+
4 --- TRD(2)+
5 --- TRD(2)-
6 ERx- TRD(1)-
7 --- TRD(3)+
8 --- TRD(3)-
NOTE
The pin numbers for the 8
-pin RJ45 connectors (and ports) are typically not labeled on the connector (or
port). Refer to the dia
gram above to see how the RJ45 pins are numbered.
Serial Console Connection
The WAC-2004A offers a serial port with DB9 male connector for its console access. The pin assignments
are shown in the following table:
Pin RS-232
1 DCD
2 RxD
3 TxD
4 DTR
5
GND
6 DSR
7 RTS
8 CTS
NOTE
The pin numbers for the male DB9 connectors are stated in the table above. The
pinhole numbers for the
female DB9 connectors are usually labeled on the connector. However, the numbers are typically very small,
so you may need to use a magnifying glass to s
ee the numbers clearly.
Power Socket
The WAC-2004A offers a dual power supply for power failover redundancy. Input voltage ranges from 100
to 240 VAC/VDC, 47 to 63 Hz, with two male C14 inlets. The WAC-2004A is shipped with 2 power cords,
one US type and one EU type. To connect the secondary power input on the WAC-2004A, an additional
power cord of the same type can be purchased separately.

Beeper
The beeper emits one short beep when the power is turned on and two short beeps when the system is
ready. When the device is located by the Search Utility, the beeper emits beeps every second to indicate its
location.
