The new board is working perfectly, but it's the old board suddenly doesn't work.
ah, ok.
How do you connect the old board to the setup, is it on the same cable like the new one.
or has it his own connector on the COM Board?
Stefan
The new board has it's own cable to the com board. The old DIO has a shared cable to the Servo board (you probably remember the problems with having the change the fuse bits on the servo board)
I was moving the cables (10pin) around to test a couple of things that weren't working on the new board and then the old one stopped.
Oh, I didn't change the fuse bits on the DIO, only the servo board
That all sound realy strange.
Do all parts of the board donīt work or only some parts?
Can you measure the 5V power on the Controller of the old board?
Stefan
Nothing works on the DIO board.
If I put the jumper on J16, the green led lights up so there is power going to the board.
Where is the easiest place to measure the 5vdc on the board?
David
pin 10 and 11 at the controller.
I would readout and verify the firmware in the Controller via PonyProg.
Stefan
Will do and I'll let you know.
David
Must be an intermittant fault, it's working now, but not sure for how long.
Ok, i had some problems with "erased" Controllers some times ago, that happend when i made a shortcut to the powersupply.
When it happens again, I'll check the voltage and whether or not I can read the firmware.
I may have shorted it out, but it doesn't seem to have erased the firmware as it's working perfectly at present.
Thanks again Stefan.
