netGSM - How does it work with HW group devices

The netGSMfunction is designed for sharing one GSM modem connected to one unit with other devices on the same network. This means that more Poseidon units can send Alarm SMS using one GSM modem thus reducing network topology and costs.

Support

The netGSM consists of a client and a server part. The server part is the Poseidon unit with the GSM modem. The clients are other units or software.

Setup parameters descritpion for Poseidon2/Damocles2 in Server mode

Serial Port Settings

Port Function sets the serial port functionality (available only on models with a serial port and netGSM server support). Options:

Disabled – The serial port is disabled – only with no modem connected and the device working as a client
GSM modem – the GSM modem is connected and the Poseidon unit works as a server for the netGSM

Remote SMS gateway

Allows to set the IP address, HTTP port and a path to the service. This routes the SMS send requests, RFID control etc. The Poseidon2, Damocles2 and HWg-SMS-GW3 units always use service.xml !

GSM SMS interface

This setups the SMS parameters

GSM Function – Allows to set if the SMS are sent through a local modem (available only if the serial port is in the GSM modem mode)
SMS+Ring when Alarm – allows to ring a phone number when sending an SMS
RS-232 GSM module – GSM modem status
Not Enabled – not active. This is shown when the RS-232 port settings are changed, but not saved
Not Found – the Poseidon is set to use the local modem, but that cannot be found
Waiting for modem – searching for the device
Initializing – the modem is initializing
Ready – the device is prepared for use
SMS center Number – for information, the SMS center number read from the SIM card. If this is not available, SMS cannot be sent

GSM SMS recipient

This allows the user to set the SMS destination numbers. It is independent on the operation mode (local / remote modem)

Setup example1

Two Poseidon units were used:

192.168.2.23 Poseidon2 4002 with a GSM modem connected
192.168.1.67 Poseidon 3266 with no modem, using the Poseidon 4002 to send SMS

Poseidon2 4002 setup (with the GSM modem)

In the default status you first need to enable the GSM modem in the Serial port Settings and then set the GSM Function to Local. Deactivating the SOAP destination is optional, as well as the SMS+ Ring when Alarm function.

Poseidon 3266 setup

In the default setting you just need to set the remote IP of the Poseidon and the SMS phone numbers. The SMS+ Ring when Alarm is optional.

Setup example2

Poseidon2 4002 units used HWg-SMS-GW3:

192.168.100.169 HWg-SMS-GW3
192.168.100.223 Poseidon2 4002 without modem, using the HWg-SMS-GW3 to send SMS

HWg-SMS-GW3 setup

HWg-SMS-GW3 used security with username and password for netGSM (SOAP)

XML setup example

Poseidon2 4002 setup

In the default setting you just need to set the remote IP of the HWg-SMS-GW3 and the SMS phone numbers. The SMS+ Ring when Alarm is optional.
