3.1.1. Electrical characteristics

Characteristic	Description
Power source	230 VAC
Analog inputs	Factory configured non isolated Analog Inputs. Admissible input range: 0 – 5 V 0 – 10 V 0..20 mA (4..20 mA configurable via software) NTC 10K
Digital inputs	Dry contact, non isolated, low tension Digital Input
Digital outputs (Relays)	Relay load: 1A 30VDC/1A 230VAC

Error

The analog inputs are not galvanic isolated. If necessary, for avoiding interference, analogical isolators can be placed externally.

Error

The digital inputs are not galvanic isolated, they have an internal pull-up and are activated by closing the circuit with GND through a dry contact.

3.2. Front panel

LED	Description
BATTERY	Battery activity Turned on when the device is powered by the battery
CHARGE	Power charge activity Turned on when the battery is charging
POWER	Power source. It’s always turned on
DATA	HSPA/GPRS connection Turned on when the HSPA/GPRS data connection is active
MODEM 3G	3G modem activity Turned on when the modem is active, even if there is no data connection active.
MODEM 2G	2G modem activity Turned on when the modem is active, even if there is no data connection active.
BUS	Modbus activity Turned on means the system is working properly. Blinking means modbus read/write operations.
RUN	Main processes activity Turned on means the system is working properly. Blinking means there is a critical system failure.

4. Installation

This chapter describes the installation procedure and first device start up.

In order to have a normal operating device, it is necessary to have at least one SIM card that allows to establish an HSPA/GPRS data connections. Please check the carrier’s data planning for prices and costs of the service.

Verify that the device is installed in a physical position in which it receives sufficient 2G/3G network coverage.

In case that 2 SIM cards are used, the policy that decides how to used them can be chosen later through the web interface.

4.1. SIM cards and connections

• Insert the SIM cards in the WE500R as the image shows. The SIM cards contacts must face down.

Warning

Avoid to insert the SIM cards when the device is turned on. After turning off the device and removing the power source, the SIM cards can be inserted/removed.

• Prepare the input and output connections in the pluggable screw terminals as required by the application.
• If required, connect the modbus cables using the serial interfaces RS232 and/or RS485.
• Connect the quad band GSM antennas with the right cable and, if required, their extension, being sure to have a satisfactory GSM signal. Check the network coverage with any mobile phone.
• Connect the power source cable an switch-on the power button.

4.2. System start-up

1. The POWER LED will turn on when the WE500R is connected to the power source. The CHARGE LED will turn on if the battery is charging.
2. After ~40 seconds, the RUN and BUS LEDs will turn on. At this point all the application and services will be active. The monitoring, control and logging applications will be running and the web interface will be reachable.
3. After ~30 seconds of step 2, the HSPA/GPRS service will become active and the GPRS LED will turn on. The services that depend on this connection such as VPN, data delivery to a portal and email will be active.

The initial WE500R configuration must take place locally in one of the two following modes:

• Point-to-point connection between the PC and the WE500R using a normal or cross Ethernet RJ-45 cable:

• LAN wired connection through a switch or hub:

The default network configuration of the WE500R is the following:

Parameter	Value
IP address	192.168.1.160
Netmask	25.255.255.0
Gateway	192.168.1.1
DNS	8.8.8.8

4.3. Logging in the web interface

In order to establish a connection enter the IP address of the device in the browser’s URL:

http://192.168.1.160

The default credentials are:

Username	Password
admin	admin

Hint

It’s strongly recommended to change the default password after the first login.

It’s necessary that the PC belongs to the same subnet of the device. In this case the private network 192.168.1.X. For connecting to the WE500R a standard Internet browser is needed. No drivers or specific software are required.

The recommended browsers that were also used for validating the web-interface are Firefox and Chrome. However, other browsers are known to work properly.

Later access to the web interface can take place through different channels assuming that the device is properly configured:

• LAN

• ADSL

• WLAN

• HSPA/GPRS

• VPN

The VPN can use any of the above channels to establish a secure connection between the WE500R and the PC. It needs a client software in the PC and a server that provides the service such as the Nethix Portal.

5. Power off and reboot

Rebooting the WE500R can be done in two ways:

1. Software: Using the proper icon at the right top of the web interface. Only an administrator can reboot the device.
2. Hardware: Pressing for 10 seconds the power button in the front panel display.

Powering off the WE500R can be done in two ways:

1. Software: Using the proper icon at the right top of the web interface. Only an administrator can power off the device.
2. Hardware: Using the Stand-by mode described later.

6. Stand-by mode

The Stand-by functionality turns off all the system applications, such as the web server and the variables monitoring, setting the system to a low power consumption state.

7. Network recovery

For executing a Network Recovery, press the front panel button and leave it pressed for approximately six seconds. During this time the following actions will be executed twice:

• The power LED will blink fast for approximately 3 seconds
• Then, all the LEDs will blink together three times

After these six seconds, the power LED will turn-on and start blinking again slowly, approximately once every two seconds, indicating that the network recovery has been executed and the system is in Stand-by mode.

Execute the procedure for leaving the Stand-by mode for booting the device normally.

This is the default network configuration after the Network Recovery:

8. Safety guidelines

• Nethix products support SIM cards from providers of all around the world, particularly from Europe Africa and Asia. However, there could be some incompatible SIM cards.
• The device cannot receive/send SMS if the SIM card is not enabled to GSM services and network or credit is not available (if prepaid card is used).
• Verify that the device is operated in an area covered by GSM network with sufficient signal strength for granting proper functioning.
• In case of questions or doubts regarding the cost of the SMS service consult your Network Provider.
• This device is only suitable for being installed by a qualified operator
• Nethix is not responsible for improper use and/or its side effects
• Nethix products are designed for typical use in industrial automation and/or home applications.
