HWg-STE connectors

Recommended connection options

Forwarding alarms to SMS (via the Email-2-SMS service):

Sensor connection options:

First steps

Connecting the cables
• Connect the unit to the Ethernet (patch cable to a switch, or a cross-over cable to a PC).
• Plug the power adapter into a power outlet and connect it to the HWg-STE power connector.
• The green Power & Mode LED in the RJ45 connector lights up.
• If the Ethernet connection works properly, the LINK (yellow) LED lights up after a short while, and then flashes whenever data transfer takes place (activity indication).
• After power-up, the LINK LED flashes rapidly to indicate IP address negotiation over DHCP.
Configuring the IP address – UDP Config
UDP Config utility – root directory of the supplied CD (Windows and Linux versions). Available for download at www.HWgroup.com Software > UDP Config.
• Click the icon to launch UDP Config. The program automatically looks for connected devices.
• To search for devices, click the Find Devices icon. The program looks for devices on your local network. Double-click a MAC address to open a basic device configuration dialog.

Configure network parameters

  * IP address / HTTP port (80 by default)
  * Network mask
  * Gateway IP address for your network
  * Device name (optional)

Click the Apply Changes button to save the settings.
Restoring factory defaults

  * Right-click on the device MAC address and select “Load default values”. Within 60 seconds after powering up the unit, factory defaults can be restored using UDP Config.
  * Disconnect the power jack, connect the jumper near the RJ11 sockets, power up the device, and wait 15 seconds. Then, disconnect the power and disconnect the jumper. The device is ready in its factory default configuration.

WWW interface of the device
• To open the WWW interface of the device:
o Enter the IP address into a web browser
o Click the IP address in UDP Config
o Click the underlined IP address in UDP
SETUP
• The WWW page displays the current states of inputs and outputs.
• Click the “Graphic Flash SETUP” link to open the graphical configuration interface (Flash Setup).

Product configuration

*added function:
Outgoing ping – function could be used as a “heartbeat”. HWg-STE will ping the target IP address.

Graph**
Graph was available in firmware versions 1.0.12 up to 2.1.6.
Due to Adobe Flash technology’s End of Life (31st of December 2020) and discontinued support in web browsers, the feature in firmware 2.1.7 has been permanently removed.
System**

*added function:
Demo Mode – Active demo mode prevents any changes in your device configuration. Demo mode can be turned off in the same way after entering the password.
