Attaching Antennas

The AWK-4121 inclues two dual-band omni-directional antenna by

default. Attach the antennas as illustrated below.

Step 1: Use your fingers and hold the antenna metal N-type connector.

Step 2: Screw the antenna N-type connector (male) onto the AWK-4121

device’s N-type connector (female)

Antenna Metal N-type

Rubber plate

Caution

Do not hold the rubber plate to screw the antenna on to the

AWK-4121 device.

ATTENTION

Use the antennas correctly: Use 2.4GHz antennas if the

AWK-4121 operates in IEEE 802.11b/g. Use the 5GHz antennas

for operations in IEEE802.11a. Make sure your antenna

installation is within a safe area covered by a lightning protection

or surge arrest system.

Wall Mounting

In most applications, wall mount provides an easier installation. You will

find it quite easy to mount AWK-4121 on the wall, as illustrated below.

STEP 1:

Attach the wall-mounting kit

with M4 screws, as shown in

the diagram below.

STEP 2:

Mounting the AWK-4121 on the wall

requires 4 screws. Use the AWK-4121

device, with wall-mounting kit

attached, as a guide to mark the correct

locations of the 4 screws. The heads of

the screws are recommended to be

between 5.5mm and 8.5 mm in

diameter, and the shafts should not be

more than 5.0 mm

in diameter, as

shown in the figure.

5.5 - 8.5 mm

< 5.0 mm

Do not screw the screws all the way in to the wall—leave a space of about

2 mm to allow room for sliding the wall-mounting kit between the wall and

the screws.

ATTENTION

You can 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 into the wall, insert the four screw heads

through the large opening of the keyhole-shaped apertures, and then

slide the AWK-4121 downwards, as indicated to the right. Tighten the

four screws for added stability.

⇒

ATTENTION

To avoid environmental vibration or shock, you can consider a

robust installation with four bigger screws, which the shafts are

between 7.0 mm and 8.5 mm in diameter, and fix the AWK-4121

onto wall directly and tightly.

DIN-Rail Mounting (Optional)

The DK-DC50131 die-cast metal kit can be

bought separately, and enable easy and

robust installation for the AWK-4121. A pair

of DK-DC50131s is needed for DIN-Rail

mounting. To install the DIN-Rail mounting

kits, tightly attach the two DIN-Rail

mounting kits on the rear panel of AWK-4121

with 12 screws. (6 screws for each kit)

To Install

STEP 1:

Use the recessed button

on the spring-loaded

bracket to lock it into

position.

STEP 2:

Insert the top of the DIN-Rail into the slot

just below the upper hook of the DIN-Rail

mounting kit. Push the AWK-4121 toward

the DIN-Rail until the DIN-Rail attachment

bracket snaps into place.

To Release

STEP 1:

Pull out the two spring-loaded

brackets from the bottom until

they are fixed in the “release”

position.

STEP 2:

Pull the AWK-4121 out and upward.

Wiring Requirements

WARNING Safety First!

Be sure to disconnect the power cord before installing and/or

wiring your Moxa AWK-4121.

Calculate the maximum possible current in each power wire and

common wire. Observe all electrical codes dictating the

maximum current allowable for each wire size. If the current goes

above the maximum ratings, the wiring could overheat, causing

serious damage to your equipment.

You should also pay attention to the following items:

•Use separate paths to route wiring for power and devices. If power

wiring and device wiring paths must cross, make sure the wires are

perpendicular at the intersection point.

NOTE: Do not run signal or communications wiring and power wiring

in the same wire conduit. To avoid interference, wires with different

signal characteristics should be routed separately.

•You can use the type of signal transmitted through a wire to

determine which wires should be kept separate. The rule of thumb is

that wiring with similar electrical characteristics can be bundled

together.

•Keep input wiring and output wiring separate.

•It is strongly advised that you label wiring to all devices in the system

when necessary.

Grounding Moxa AWK-4121

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. There must be no

potential difference between two ground potentials, otherwise

there is a risk that the device could be destroyed.

Wiring the Redundant Power Inputs

The AWK-4121 must be connected to a power-over-Ethernet (PoE) IEEE

802.3af compliant power source or an IEC60950 compliant limited power

source. When AWK-4121 is powered via DC power, the M12 A-coding

connector on the bottom panel is used for the AWK-4121’s two redundant

inputs. The pin assignment is shown below:

Pin Power Input

1 V1+

2 V2+

3 V1-

4 V2-

5 GND

- 7 -

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).

Make sure External Power Adaptor (includes power cords and

plug assemblies) provided with the unit is certified and suitable

for use in your country.

Before connecting the AWK-4121 to the DC power inputs, make

sure the DC power source voltage is stable.

Wiring the Digital Inputs and Relay Contact

(Digital Output)

The AWK-4121 has two sets of digital input—DI1 and DI2. Each DI

comprises two contacts of the 8-pin M12 connector on the AWK-4121’s

bottom panel. These two digital inputs can be connected to

digital-output-enabled sensors for on-site status monitoring.

The AWK-4121 also has one relay output, which consists of the two

contacts. These relay contacts are used to detect user-configured events.

The two wires attached to the Relay contacts form an open circuit when a

user-configured event is triggered. If a user-configured event does not

occur, the Relay circuit will be closed.

A field-installable plug, M12A-8PMM-IP68, is recommended for

connecting the AWK-4121’s DIs and relay.

10/100BaseT(X) Ethernet Port Connection

The 10/100BaseT(X) ports located on the AWK-4121’s bottom 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.

RS-232 Connection

The AWK-4121 has one RS-232 (8-pin RJ45) console port located on the

bottom panel. Use either an RJ45-to-DB9 or RJ45-to-DB25 cable to

connect the Moxa AWK-4121’s console port to your PC’s COM port. You

may then use a console terminal program to access the AWK-4121 for

console configuration.

NOTE 1. The pin numbers for male DB9 and DB25 connectors, and

hole numbers for female DB9 and DB25 connectors are

labeled on the connector. However, the numbers are

typically quite small, so you may need to use a magnifying

glass to see the numbers clearly.

2. The pin numbers for both 8-pin and 10-pin RJ45 connectors

(and ports) are typically not labeled on the connector (or

port). Refer to the Pinout diagram above to see how RJ45

pins are numbered.

ATTENTION

To ensure the IP68-rated connectivity, you must use a

waterproof housing during any communication activities. An

IP68-rated field installable plug, which is attached in AWK-4121’s

accessory pack, may be needed in this case. The installation

guide is shown below:

Installation

STEP 1:

Attach the gasket ①to the housing ③

STEP 2:

Insert the cable (ex. CAT5e) through the clamp ring ④, screw nut ②, seal

⑤and housing ③, as follows:

STEP 3:

Crimp the modular RJ plug to the cable; (NOTE: the snagless cover shield

and strain-relief boot are not recommended.) Then, assemble the seals

and the housing (③and ⑤).

STEP 4:

Tightly screw the clamp ring ④to the

housing and check to make sure that

the plug is securely fastened.

(NOTE: for a tighter connection, you

can connect the RJ-45 plug to the

AWK-4121 before STEP 4.)
