Default USB to RS232 Converter Problem
This seems to be common with Rabbit equipment.
I’m using (well trying to) a BL2000
Have paid for 2 different USB-RS232 Converters, and neither work.
Both do the same, give comms problem notice.
Yes, I’ve tried un-checking the “Enable Processor Verification”
(and every other combination of options I can )

I note that the green ‘power’ light keeps blinking which I see
by the schematic is really the processor RST line.
Down loaded latest Dynamic C 9.52, no change.
The Rabbit guys have really failed on this one, they should
put out a global notice and let people know before they buy a rabbit system
“warning will not work with USB”
I’ve lost hours of time trying to nut this one out.
Has anyone found a reliable fix yet ?

Did you use an FTDI based USB to RS232 unit?

I have been thinking of buying one but if they don’t work I won’t.

I just bought a USB to RS232 convertor from USB Gear http://usbgear.com/USBG-232MINI.html and it works fine. By default, it sets up COM 3, so you have to change your settings, but that was the only hiccup I experienced with it. The really nice part is that it also has Vista drivers. I got mine for a few bucks off of E-bay.

Good Luck!

I guess I should state that I am using the LP3500, not the BL2000.
