I have everything working on the desk but as soon as I put a long cable from my control panel to my photocell I get intermittent start stops,resets and snaps in no particular order. I have a few questions;
For some reason my snap external control is pins 9-8, start stop is 8-7 and reset is 8-6, basically 8 seems to be common and I have all my external control tied to 8 as common and also the appropriate pin for the command I want. First question, is that normal?
My start/stop and reset work great as intended. Snap is the issue, It works fine when I close the connection on pins 9-8 in the usb to rs-232 adapter as well as on the same terminals in the panel I built as well as with short cables (3') plugged into the panel. As soon as I plug my 50' cable in I get crazy things happening; intermittent start/ stops,resets and snaps in no particular order. I have tried an extension cord, coax and 18GA speaker wire and I get the same results. The strange thing is that when I set my multimeter to 200ohms for resistance and place the leads across the snap pins the snap control works. I am going to use a resistor that duplicates this but I was curious if you have run across this before?
In Windows XP when I change the delay skip triggering to 10,000 or anything over 100 I get an error and the Xnote will not start,how do I delay skip triggering in Windows XP?
Thanks again for all your help!!
