The Navman MDT-850 is a User Programmable Terminal/Controller
The versatile MDT-850 terminal allows designers to very quickly bring GPS and GSM applications to fruition. The MDT units contain a 16 bit microprocessor, 832K of program memory, 10K of RAM and 32K of NVRAM, also 128K of battery backed SRAM on the MDT-850 combined with a backlit LCD display (160 x 80 pixel, 4 grey levels) and 13 pushbutton keys. There are also two serial ports (RS232), typically allowing connection to both a GSM unit such as the MC35T and a GPS unit. The whole unit runs from a normal car power supply, and is CE and 'E' marked. Development is achieved by the use of the MDT-850 SDK (Software Development Kit), and a 'C' compiler for the Mitsubishi M16 (M30620) processor (three month trial version is available to download from the web at no cost). The SDK includes download utilities, libraries, example programs and your first MDT-850 terminal, allowing product development to start immediately for a very low cost. A free demonstration program is available on request. For customers using the MDT-800 or MDT-850 and requiring a production test program, code can be requested. SDK Update - If you are using Windows 2000 or Windows XP and are having trouble with the ISP utility, then request a download of the replacement ISP.ini file.
