Description The GDW-11 provides a reliable data communication link over GSM/GPRS networks. The unit has been designed for use in industrial data communication applications and has several features that are not normally present on standard GSM modems. The GDW-11 is a DIN-rail mounted modem with RS-232 interface in a 9-pin D-sub. The GDW-11 485 also has an RS-422/485 interface in screw terminal block.

Windows configuration tool GD-Tool The GD-Tool is a PC – application program with a graphical interface for easy configuration of the complex functions found in the GDW-11. Please refer to GD-Tool for a complete description of the functionality of the Windows program. Start up guide Follow the steps below to get the unit up and running in a simple application Default settings of the serial interface are: … AT+IPR=9600 9.6 kbit/s … AT+ICF=3,4 8 databits, no parity and 1 stop bit.
Configuration The GDW-11 can be configured from the local DTE interface. When the local interface is used the configuration can be made with AT-commands on the serial interface, or with a PC-based application configuration tool. Factory default settings can also be obtained by using a DIP switch locally. Standard mode is used for basic GSM modem functionality Advanced mode adds extended command set and functions. See AT+WOPEN.
