The GDW-11 is a modem designed to allow connection of legacy serial equipment over a GSM/GPRS network. The AT command driven modem operates over the GSM/GPRS networks providing speed up to 14.4 kbit/s on GSM or 85.6 kbit/s when using GPRS.

The GDW-11 is designed for use in heavy-duty industrial applications. The wide power range, galvanic isolation guarantee communication in the worst environments. Only industrial-grade components are used, which gives the GDW-11 an MTBF of 1,100,000 hours and ensures a long service life. A wide operating temperature range of –25 to +50°C (–13 to +122°F) is achieved with no moving parts. The GDW-11 has been tested both by Westermo and external test houses to meet many EMC, isolation, vibration, and shock standards, all to the highest levels suitable for heavy industrial environments and rail trackside applications.

The modem is simple to configure both by DIP switches as well as by the Westermo GD-tool software; standard commands can easily be entered, and saved configurations downloaded. RS-232 connections can be made using screw connections as well as the standard D-sub. The modem is designed to be connected to devices with no ability to control dialing, so special functions like data dialing and DTR dialing are provided to enable these devices to automatically establish connections.

 

End of Life Product - Replacement Available

Please note that the GDW-11 has been phased out and replaced by the Merlin-4407-T4-S2-LV.
