Chapter 1. Connecting the ports

1.1

Connectivity

Input, output connections

1 –SIM-card holder (push-insert)

2 –SMA antenna connector (Narrow Band antenna, 50 Ohm)

3 –PWR +/-: Power supply connector (8-24VDC, min. 300mA)

4 –IN1, IN2: 2pcs connector for input lines (for impulse capable meters)

5 –NOT USED connector

6 –Jumpers for the input lines (IN1, IN2) to select the operation mode

galvanically independent voltage input –NOT USEFUL

contact input (detection of wire cut (by using a 10kΩ EOL resistor) or short) –

YOU HAVE TO CHOOSE THIS FOR IMPULSE COUNTING

7 –PROGRAM CONNECTOR: micro USB (for configuration, software upload)

1.2 Cabling and wires

Preparation

Take the 4 spacer fixing tabs provided with the device, and place them into the PCB holes as

shown in the picture.

Prepare a screwdriver, the 2 terminal blocks

provided with the device, and the stripped

wire pair necessary for connection, with

appropriate distinctive colors (power

connector –e.g. black-red, input-output wire

pairs –e.g. black-blue, alarm input –e.g.

black-white).

Connecting the inputs

The device has 2 input lines (IN1, IN2), where

external impulse-signal capable devices (meters) can be connected –e.g. water or gas meter -

by its wire pairs, in accordance with the standard connection method shown below, by fixing the

cable wire pairs for each input.

The input mode can be selected by the internal jumpers –beside the terminal block of the input

lines (3-3 pins for IN1, and 3-3 pins for the IN2) –according to the input line nr. titles.

Take care for the proper position of the jumpers. The contact (impulse) operation mode must

be also configured as well with the

EasyTerm

application.

Input line operation mode (selection by jumpers):

Contact mode (DRY)

oPut the jumper (CLOSE) on the IN1 or IN2 line’s 2-pins (two pair of pins),

each pair must be jumpered on the closer side of the terminal block

(connector) –as you can see in the picture.

Signal levels in DRY mode:

Contact resistance: 0 –1kOhm

Impulse signal frequency: 0 –500Hz

When the inputs are activated (IN1, IN2) the INx LEDs are signing the active (closed) status

during the operation, with the proper light and colour. See

LED signals

part.

EOL resistor (for DRY mode)

For the detection of wire cut, you have use and connect a 10kΩ resistor by parallel to

the contact.

Voltage mode (WET)

oPut the jumper on the IN1 or IN2 line’s 2-pins (two pair of pins), each pair

must be jumpered closer to the LED side –as you can see in the following

picture.

Signal levels (WET mode –voltage input):

Input high signal level: 8 - 24V

Input low signal level: 0 - 1V

Impulse signal frequency: 0 –500Hz

When the input were activated (IN1, IN2) the INx titled LEDs are signing the active (high signal

level) status during the operation, with the proper light and colour. See

LED signals

part.

Connecting the power supply

The 8-24V power-supply voltage (typically 12V

power adapter, or 24V power supply) can be

connected to the PWR input through a wire

pair. When connecting the power, the device

will be immediately started to operating, when

the PWR LED will indicate it with the

appropriate color/light.

Attention!

Do not forget to insert the SIM-card previously –see Chapter nr. 2. Pay close

attention to polarity! Holding the serials facing us, the right side of the PWR connector is the

positive pin and the left side is the negative pin!

1.3 LED signals

The status LEDs are helping to understand the current operation of the device.

GSM: wireless network status LED - red

The numbers of the GSM LED flashing sequence signs the current RSSI signal strength of the

wireless network (more flashes are meaning a better signal reception).

There is 10 seconds between the flash signals. One flashing takes 50 msec, then half a second

breaking continues.

STA: Status LED - yellow

The STA LED assures information about the current operation. It will be active only if the

wireless signal transmission permitted. In this case from the beginning of the signal transmission

the LED starts to flashing.

It has 3 modes:

lighting continuously: the last wireless signalling was succesful

with 3 second of breaks * nr. of flashing (the light interval period is half a seconds),

failure code (see later)

Turned off: wireless operation mode, no error

Failure codes –for signing the device opreation troubles –in case of a failure, read the

Troubleshooting Chapter.

1 flash - Module failure

The serial connection is not operating properly between the module and the

Easy 2S NB

board. After 1 minute, the device automatically tries to restart the module.

2 flashing - SIM card failure

Possible reasons:

othere is no SIM card inserted

oSIM card pinpad contact error

The device in this status will not continues its initialization, the receiving of serial port

commands is still active (for parametrizing). After 1 minute, the device automatically tries

to restart the module.

3 flashing - PIN authentication failure

Possible reasons:

owrong PIN code

oPUK code (security code) is necessary to give in

The device in this status will not continues its initialization, the receiving of serial port

commands is still active (for parametrizing). After 5 minutes, the device automatically

tries to restart the module.

4 flashing –The device cannot login to the GSM network

Error during the network registration. After 5 minutes the device restarts the modem

and retries.
