Step 6: Test communications We will describe two test methods. Use the first method if you are using only one AWK-3121, and use the second method if you are using two or more AWK-3121s. Testing method for one AWK-3121 If you are only using one AWK-3121, you will need a second notebook computer (B) equipped with a WLAN card.
AWK-3121 connected to notebook A, and change the second or third AWK-3121 connected to notebook B to Client mode and then configure the notebooks and AWK-3121s properly. After setting up the testing environment, open a DOS window on notebook B.

If you need to reattach the DIN-Rail attachment plate to the AWK-3121, make sure the stiff metal spring is situated towards the top, as shown in the figures below.
STEP 2: 6.0 mm Mounting the AWK-3121 to a wall requires 4 screws. Use the AWK-3121 device, with wall mount plates attached, as a guide to mark the correct locations of the 4 screws. The heads of the screws should be less 3.5 mm...
Grounding the 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.
Wiring the Redundant Power Inputs The top two pairs of contacts of the 10-contact terminal block connector on the AWK-3121’s top panel are used for the AWK-3121’s two DC inputs. Top and front views of the terminal block connector is shown here.
Cable Holder Installation (Optional) You can attach the cable holder to the bottom of the AWK-3121. This helps to keep cabling neat and avoid accidents that result from untidy cables. STEP 1: Screw the cable holder onto the bottom of the AWK-3121.
The AWK-3121 has one RS-232 (8-pin RJ45) console port located on the front panel. Use either an RJ45-to-DB9 or RJ45-to-DB25 cable to connect the Moxa AWK-3121’s console port to your PC’s COM port. You may then use a console terminal program to access the AWK-3121 for console configuration.
