4.4 HSComm GPRS
The configuration of the INSYS GPRS 5.0 serial takes place via AT commands which are entered by a terminal program or a control program in the form of character sequences. For a simpler set-up, all basic functions of the INSYS GPRS 5.0 serial can be entered without knowing the individual AT commands and their parameters, using the configuration software HSComm GPRS.
The software can be installed on the operating systems Microsoft Windows 2000 and Microsoft Windows XP. A terminal window to enter commands directly is available.
In Chapter 5 - Connections - and Chapter 6 - Functions -, the HSComm GPRS or an­other terminal program can be used for the configuration. The AT commands can be directly entered into the HSComm GPRS at the menu item “Terminal”.
The HSComm GPRS checks the connected device during startup. By default, only those settings can be selected which are implemented in the identified device.
The buttons in the right column can be used to select the current settings, to re­start (reset) the device, or to set the factory settings (default).
The current can be saved as a file at the menu item "File" in the main menu at the top window border, and reloaded at a later date.
The selected configuration of the parameters is only sent to the INSYS GPRS
5.0 serial after you click on the button Send values.
