KD485-PROG-422-20MA Universal Isolated Interface Converter

This interface converter is similar to the KD485-ADE with the addition of a 32kbyte EEPROM into which application specific data conversion programs can be loaded. It is typically used for protocol conversion applications. A MODBUS RTU SLAVE library is available to speed up the development of custom Modbus RTU converters.

The KD485-PROG can be configured with any "dumb" terminal or a PC. A GUI-based Windows configuration program, KDCFG.EXE, for Win9x/NT/2000/XP/Vista/7/8/10 is included on a CD. Configuration is done via Port 1 so an RS422 interface for the PC is required. Programs can be written in ANSI C or assembler. C programs up to 10,000 lines have been successfully developed for the KD485-PROG.

Port 1 is RS422 or RS485. Port 2 is 20mA loop (TTY).
