What can be used in place of PM Systems

hey meta - this may seem a stupid question - are you checking the settings for the security bits in the display manual(pdf) in docs folder? Also make sure your com port and serial cable are correct and set correctly.

I have a an IO card that is hooked up to the COM card and I am following the procedure as described in dio_en.pdf. I'm pretty sure the COM card is OK, since the loopback test works now, and while attempting to flash the card, the yellow led flickers. When I do step 6 (set the security and configuration bits), the program issues an error.

I had exactly the same problem and i checked on the 74hc04 IC there is a track from the 6pin flash header that run down and between pins 5 and 6. Also check for a short between pins 2 and 3. Once i fixed the short between 5 and 6 it was working and flashing. Now if i could only find the issue with the IO card LOL
