Overview Moxa’s AWK-3121-M12-RTG access point/client is ideal for applications that are hard to wire, too expensive to wire, or use mobile equipment that connects over a TCP/IP network. The AWK-3121-M12-RTG is rated to operate at temperatures ranging from -25 to 60°C for standard models and -40 to 75°C for extended temperature models, and is rugged enough for any harsh industrial environment.

Step 3: Set up the computer’s IP address Set an IP address on the same subnet as the AWK-3121-M12-RTG. Since the AWK-3121-M12-RTG’s default IP address is 192.168.127.253, and the subnet mask is 255.255.255.0, you should set the IP address of the computer to 192.168.127.xxx and subnet mask to 255.255.255.0.
Panel Layout of the AWK-3121-M12-RTG 1. Grounding screw (M3) 2. Terminal block for PWR1, PWR2, relay, DI1, and DI2 3. Reset button 4. Heat dissipation orifices 5. System LEDs: PWR1, PWR2, PoE (Hardware Rev. 3.0.0 supports PoE; hardware Rev. 2.0.0 does not support PoE.), FAULT, and STATE LEDs 6.
Mounting Dimensions (unit = mm) DIN-Rail Mounting The aluminum DIN-rail attachment plate should be fixed to the back panel of the AWK-3121-M12-RTG when you take it out of the box. If you need to reattach the DIN-rail attachment plate to the AWK-3121-M12-RTG, make sure the stiff metal spring is situated towards the top, as shown in the figures below.
Wall Mounting (optional) For some applications, it may be more convenient to mount the AWK-3121-M12-RTG to a wall, as illustrated below. STEP 1: Remove the aluminum DIN-rail attachment plate from the AWK-3121-M12-RTG, and then attach the wall mount plates with M3 screws, as shown in the adjacent diagrams.
WARNING • This equipment is intended to be used in a Restricted Access Location, such as a dedicated computer room, where access can only be gained by SERVICE PERSONS or by USERS who have been instructed about the fact that the metal chassis of the equipment is extremely hot and may cause burns.
ATTENTION This product is intended to be supplied by a Listed Power Unit marked “Class 2” or “LPS” and rated O/P: 12 to 48 VDC, minimum 6 W (12 V/0.494 A to 48V/0.121 A), 25°C. ATTENTION Make sure the external power adapter (includes power cords and plug assemblies) provided with the unit is certified and suitable for use in your country.
Installations with Cable Extended Antennas for Outdoor Applications If the antenna or the AWK device is installed outdoors or in an open-air setting, proper lightning protection is required to prevent direct lightning strikes on the AWK device. In order to prevent coupling currents from nearby lightning strikes, a lightning arrester should be installed as part of your antenna system.
ATTENTION Before connecting the AWK-3121-M12-RTG to the DC power inputs, make sure the DC power source voltage is stable. Wiring the Relay Contact The AWK-3121-M12-RTG has one relay output, which consists of the two contacts of the terminal block on the AWK-3121-M12-RTG’s top panel. Refer to the previous section for detailed instructions on how to connect the wires to the terminal block connector, and how to attach the terminal block connector to the terminal block receptor.
Communication Connections 10/100BaseT(X) Ethernet Port Connection All AWK-3121-M12-RTGs have a 10/100BaseT(X) Ethernet port (4-pin shielded M12 connector with D coding). The 10/100TX port located on the AWK-3121-M12-RTG front panel is used to connect to Ethernet-enabled devices. Most users configure this port for Auto MDI/MDI-X mode, in which case the port’s pinouts are adjusted automatically depending on the type of Ethernet cable used (straight-through or cross-over), and the type of device (NIC-type or HUB/Switch-type) connected to the port.
LED Indicators The front panel of the Moxa AWK-3121-M12-RTG contains several LED indicators. The function of each LED is described in the table below.
