1.3 Expansion boards

There are the following options to order the product:

-optional MBus add-on board

-supercapacitor option

1.4 Power on the modem

The WM-E8S modem can be powered from ~85..300VAC / 100..385VDC power source

at the N (neutric) and L (line/phase) AC / DC connection pins of the terminal block.

1.5 MBus connection –order option

The modem’s Mbus master connection can be used for max. 4 slave devices, which

can be connected to the +/- pins of the MBus terminal block. The modem provides 24-

36V DC power for the connected Mbus devices.

1.6 Current loop connection

The modem current loop connection can be performed on the +/- connection pins of

the CL terminal block.

1.7 Digital input (DI) connection

The modem digital input connection can be performed on the Input A, B and COM

connection pins. For testing, a short must be made between the COM and A or COM

and B.

1.8 RS232/RS485 connection (RJ45 connector)

The modem RS232/RS485 connector should be wired to the RJ45 connector.

The RS232 uses the pin nr. 1, 2, 3 and pin nr. 4 for DCD Control

The RS485 (for 2-wire connection) uses the pin nr. 5, 6

The RS485 (for 4-wire connection) uses the pin nr. 5, 6, 7, 8

Alternatively you can use the secondary RS485 port on the terminal block.

The modem uses the TCP port nr. 9000 for the transparent communication and port

nr. 9001 during the configuration. The Mbus is working on the port nr. 9002 (baudrate

can be selected between 300 and 115 200 bps).

1.9 Modem configuration

The modem has a pre-installed system (firmware). The operational parameters can be

configured with the WM-E Term®software (through its RJ45 connector in RS232

mode).

The necessary settings of the WM-E Term®software - for SIM APN configuration and

modem force into cellular/mobile communication technology - are described in the

user manual’s Chapter 3.4.

2.1 Configuration cable / connection

Use the RJ45 connector for meter connection (for RS232 or RS485 connection) or serial

connection (in RS232 mode) for configuration to the PC.

The pinout of the device’s RJ45 port can be seen below.

RS485 2- or 4-wire connection:

Configure the modem for RS485 meter connection –

2-wire or 4-wire mode:

PIN #5: RX/TX N (-) –for 2-wire and 4-wire connection

PIN #6: RX/TX P (+) –for 2-wire and 4-wire connection

PIN #7: TX N (-) –for 4-wire connection only

PIN #8: TX P (+) –for 4-wire connection only

Serial RS232 connection:

PIN #1: GND

PIN #2: RxD (receiving data)

PIN #3: TxD (transmitting data)

PIN #4: DCD

Make serial connection from the modem to a PC or a

meter by wiring RJ45 connector’s Pin #1, Pin 2, and Pin

#3 –optionally pin nr. #4.

2.2 Prearing to start the device

Step #1: In powered off status, ensure that the plastic terminal cover (marked by „I”) is

placed on the device enclosure („II”) before continue.

Step #2: An active SIM card (2FF type) must be inserted to the modem’s SIM holder.

Take care to the direction of insertion (follow the hints of the next photo). The proper

orientation / direction of the SIM can be seen on the product sticker.

Step #3: Connect the wired serial cable to the RJ45 connector (RS232) according to

the pinout above.

Step #4: Attach an external LTE antenna (800-2600MHz) to the SMA antenna

connector.

Step #5: Add ~85-300VAC or 100-385VDC power voltage to the AC/DC titled connector

and the device will starting its operation immediately.

Caution! Please consider the following, ~85-300VAC or 100-385VDC

electric shock hazard inside the enclosure! DO NOT open the

enclosure and DO NOT touch the PCB or its electronical parts!

AC/DC: connect ~85..300VAC or 100..385VDC power

/: GND of Digital inputs (DI)

MBUS*: Optional

*Instead of the secondary RS485 port you can order MBUS port

RS232/

RS485

ANT

AC / DC

RS485

SAFETY CAUTION!

The IP52 immunity protection will be effective only in case of under normal usage

and operation conditions with unharmed hardware conditions by using the

device in the provided enclosure/chassis.

The device must be used and operated according to the related user manual.

The installation can be carrying out only by a responsible, instructed and skilled

person by the service team, who has enough experience and knowledge about

carrying out the wiring and installing the modem device.

Its prohibited to touch or modify the wiring or the installation by the user. It is

prohibited to open the device enclosure during its operation or under power

connection.

It is also prohibited to remove or modify the device PCB. The device and it’s parts

must not be changed by other items or devices. Any modification and repairation

is not allowed without the permission of the manufacturer. It all causes the loss

of product warranty.

2.3 Status LED signals

* LED 1 will be flashing faster if it was registered on wireless network

** LED 4, 5 is available only in case of MBUS version.

2.4 Configuration the device

Step #1: Download the WM-E TERM configuration software to your computer by this

link: https://www.m2mserver.com/m2m-downloads/WM-ETerm_v1_3_69.zip

Step #2: Unpack the .zip file into a directory and execute the WM-ETerm.exe file. (The

Microsoft®.Net Framework v4 must be installed on your computer for the usage).
