i do DMG service, so i kinda know a bit about them LOL. not all 432 controls, especially early ones did drip feed, but they could be upgraded with a newer CPU and software. (not cheap though). If your not sure if you can drip feed look for a softkey called BTR (means between the tapereader). if you have this softkey then it should work. The communications constants usually start somewhere above N700 in the constants display. Scroll up and read the discription for each constant. you will need to match them up to your computer for RS232 communication. BTW a simple 3 wire is all that's needed |
