Overview Moxa’s AWK-1121 WLAN 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-1121 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.

Mounting Dimensions (unit = mm) DIN-Rail Mounting The aluminum DIN-Rail attachment plate should be fixed to the back panel of the AWK-1121 when you take it out of the box. If you need to reattach the DIN-Rail attachment plate to the AWK-1121, 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 theThe DIN-Rail attachment unit will slot just below the stiff metal spring. snap into place as shown below.
Wall Mounting (optional) For some applications, it may be more convenient to mount the AWK-1121 to a wall, as illustrated below. STEP 1: Remove the aluminum DIN-Rail attachment plate from the AWK-1121, and then attach the wall mount plates with M3 screws, as shown in the adjacent diagrams. STEP 2: Mounting the AWK-1121 to a wall requires 4 screws. Use the AWK-1121 device, with wall mount plates attached, as a guide to mark the correct locations of the 4 screws.
Wiring Requirements WARNING Safety First! Be sure to disconnect the power cord before installing and/or wiring your Moxa AWK-1121. WARNING Safety First! Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes dictating the maximum current allowed for each wire size. If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment.
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 4-contact terminal block connector on the AWK-1121’s top panel is used for the AWK-1121’s two DC inputs. The top and front views of the terminal block connector are shown here. STEP 1: Insert the negative/positive DC wires into the V-/V+ terminals.
Communication Connections 10/100BaseT(X) Ethernet Port Connection The 10/100BaseT(X) ports located on the AWK-1121’s top panel are used to connect to Ethernet-enabled devices. Below we show pinouts for both MDI (NIC-type) ports and MDI-X (HUB/Switch-type) ports. MDI Port Pinouts Pin Signal 1 Tx+ 2 Tx3 Rx+ 6 Rx- MDI-X Port Pinouts Pin Signal 1 Rx+ 2 Rx3 Tx+ 6 Tx- 8-pin RJ45 RS-232 Connection The AWK-1121 has one RS-232 (8-pin RJ45) console port located on the front panel.
