Benefits

Benefits

• Web-based configuration.
• No software is needed to run anywhere in order to send text messages.
  • Box-2-Box mode allows two devices (e.g. a Poseidon2 and the SMS GW) to communicate over the LAN.
• Message recipient's phone number is configured in the sending device. One HWg-SMS-GW text message gateway can send SMS alarms to dozens of different recipients.
• SMS gateway supports a "SMS + Ring" function that dials a call to the alarm message recipient's number and lets the phone ring for a short time.
• With an external antenna, the device can be used even at places with poor GSM coverage (data center).
• Quad-Band GSM modem works with GSM coverage anywhere in the world.
• Examples for programmers on using the product are available in the HWg-SDK (Borland C++, MS Visual C, VB, C#, PHP, JAVA and more).

Sending SMS alerts from Poseidon units over the LAN

• Poseidon2 4002 sends an alarm message about a sensor value to Mr. Blue's phone number.
• Using the Box-2-Box mode, it connects directly to the HWg GSM gateway (no software is needed).
• HWg-SMS-GW contains a SIM card and sends cell message alerts on behalf of all devices in the network.
• Message recipients' phone numbers (Mr. Purple, Mr. Green, ...) are configured in the sending device.
• Together with the text message, it is also possible to call the recipient and let the phone ring for a short time (configured in the sending device).

HWg-Trigger: Monitoring software with SMS alarms over SMS GW

• HWg-Trigger, an application for MS Windows, monitors the function of other products (Poseidon2 3266, HWg-STE Push, Damocles 1208, Poseidon 4002) over the LAN.
• If a product is inaccessible or fails, a SMS alert is sent using HWg-SMS-GW in the same LAN.
• Recipients' phone numbers (Mr. Purple, Mr. Green) are configured in HWg-Trigger.
• HWg-SMS-GW contains a SIM card and sends text message alarms to different phone numbers.

Nagios SMS alerts

• Nagios NMS monitors other devices using SNMP.
• In the Nagios system, a plugin enables SMS alerts over HWg-SMS-GW gateway.
• The plugin configuration includes the phone numbers of text message alert recipients.
• For details about obtaining and using the Nagios plugin, see the product manual.
• The plugin was created in cooperation with Netways (MonitoringExchange: notify-poseidon-sms.pl).

SMS alerts from the SensDesk.com online portal

• LAN and GSM sensors (HWg-STE Push and Ares 12) send data to the SensDesk.com online portal.
• Your user account includes the IP address or DNS name of your HWg-SMS-GW (must be accessible at a public IP address).
• The configuration of each sensor in your SensDesk account can include a phone number for alarm messages.
• Note:

Ares 12 sends the alert to an out-of-range sensor value faster than the SensDesk portal; however, SensDesk allows to monitor and configure all alarms over the Web at a single place. In addition, SensDesk also monitors the network connectivity of Ares units, so it can for instance alert to an Ares unit's network connection failure.
