A mate of mine had a pdp in his garage, long after they were dinasaurs of course.
Tera term seems alright, turns out the issues are with my rs232 to usb converter, it has odd rates when you get down to very low ones.
My prolific rs232 to usb seems a lot better though, th eonly thing with the prolific is its true rs232 and therefore requires a max232 on the o/p of the pic, my 99p china special rs232 to usb accepts rs485 so you can comnnect it direct to the pic.
After a discussion with 'the customer' turns out that instead of 4 aquisition units theres now only going to be 2 and them in the same box, theres no need to aquire data from all 4 traction motors when you want to know energy consumed, so now we are going to have one on the drive controller and another on the brake resistors, I have a couple of clip on current transformers with 0-10v o/p, that makes things way easier.
On field trials tomoz I'm going to try various rs232 baud rates, and I'm also going to take a rig that uses a couple of 433 mc's rf modules, as I found out they use pmr446 on board, so if that works there must not be that much noise at uhf and rf modules might so the trick, no wires at all then, I've dug up some coding I did years ago to genrate rtty tones, just playing around with mmtty now.
