Overview Are your applications hard to wire, or are your wiring costs out of control? Are you already using mobile equipment that connects over a TCP/IP network? If so, then what you need is the AWK-3121Access Point/Bridge/AP Client. The AWK-3121 is rated to operate at temperatures ranging from 0 to 60°C for standard models and -40 to 75°C for extended temperature models, and is rugged enough for any harsh industrial environment. Installation is easy, with either DIN-Rail mounting or distribution boxes.
NOTE For security reasons, we strongly recommend changing the password. To do so, open the Network Manager homepage, click on Maintenance > Password, and then follow the onscreen instructions. Step 5: Select the operation mode for AWK-3121 By default, AWK-3121’s operation mode is set to AP. You can change the setting if you would like a Client mode or other operation mode. NOTE To make the change effect, you must click Activate button after you change the settings.

DIN-Rail Mounting The aluminum DIN-Rail attachment plate should be fixed to the back panel of AWK-3121 when you take it out of the box. If you need to reattach the DIN-Rail attachment plate to AWK-3121, make sure the stiff metal spring is situated towards the top, as shown in the figures below. STEP 1: STEP 2: Insert the top of the DIN-Rail into the The DIN-Rail attachment unit will snap slot just below the stiff metal spring. into place as shown below.
NOTE Test the screw head and shank size by inserting the screw into one of the keyhole shaped apertures of the Wall Mounting Plates, before it is screwed into the wall. STEP 3: Once the screws are fixed in the wall, insert the four screw heads through the large parts of the keyhole-shaped apertures, and then slide AWK-3121 downwards, as indicated below. Tighten the four screws for added stability.
Grounding MOXA AWK-3121 Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw to the grounding surface prior to connecting devices. ATTENTION This product is intended to be mounted to a well-grounded mounting surface such as a metal panel. Wiring the Redundant Power Inputs The top two pairs of contacts of the 10-contact terminal block connector on AWK-3121’s top panel are used for AWK-3121’s two DC inputs.
Wiring the Digital Inputs AWK-3121 has two sets of digital input—DI1 and DI2. Each DI comprises two contacts of the 10-pin terminal block connector on AWK-3121's top panel. You can refer to the section Wiring the Redundant Power Inputs 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.
LED Indicators The front panel of MOXA AWK-3121 contains several LED indicators. The function of each LED is described in the table below. LED PWR1 PWR2 PoE FAULT STATE SIGNAL (5 LEDs) BRIDGE MODE CLIENT MODE WLAN 100M 10M Color State Description Front Panel LED Indicators (System) Power is being supplied from On power input 1.

Cable Holder Installation (Optional) You can attach cable holder on the bottom of MOXA AWK-3121. It can make cabling neat and avoid accident that results from untidy cables. STEP 1: Screw the cable holder onto the bottom of AWK-3121. STEP 2: After mounting AWK-3121 and plugging LAN cable, tighten the cable along the device and wall.
