Hi,
I've encountered some problems assembling the interface/charger board.
After installing the 16-pin socket for U16 and the capacitors and then
mounting the MAX232 chip, I then applied power to the board. But, the PWR
LED did not lit up and the voltage at pin2 of U16 did not read +10 volts.
I'm quite positive the orientation of the capacitors is correct.
The test to check the MAX232 chip's ability to transmit data did check out.
Anyone know what might be wrong?
thanks,
phet
