U2 Pin 13 to +5V short...
Hi Guys, Thanks again for the support. Yeah it's a V4 board. Before I wrote my most recent post, I was staring for some time, at that short trace from U2 Pin 13 to X1, only being 30mm long at most, thinking I must have missed some other link. You've confirmed I haven't at least! I'm reading 0 ohms b...

I found that I could use Hyperterminal to return all characters entered when using a wire jumper between Tx and Rx on just the lead, when unplugged from the board. As soon as it was plugged i...

Additional Tinkering...
As an additional note after some further playing:- I've tested all voltages throughout the board, up and down current of all diodes, as you have suggested on other posts - all voltages are correct. I've tested all capacitors with a capacitance tester in such a way that proves the solder joints are s...

Further Testing
Hi Brent, Ok, I've tried to get the unit to talk to the Configuration Software. It returns a 'Timeout reading cylinder count'. I've also tried to get a reponse from the unit using Hyperterminal and get nothing. I'm using a home made Serial cabe which was built following the instructions on the site....

Firmware Uploading Problem: - Continuous Counting.
Hi Everyone, I'm new to to MJLJ but am resonably experienced at building circuitry and have followed the 'Assembly Instructions' to the letter when building my kit. I've conducted all the tests suggested and get all the correct outputs. I've come to upload the firmware onto the unit from my PC follo...
