| Hi. This evidence pretty conclusively points to a power-ground short on your board. Here is why: * you are fairly certain it is not the RJ11 cable (the most common cause of blown R11's). * when applying charge pwr directly to the HB's charge jack, (...)

Where .0068 is the cap, and 32.75 was my desired frequency. So x was determined to be 4.49 (...) (27 years ago, 23-May-97, to lugnet.robotics.handyboard)

| | Re: Re[2]: phone cord length

| (...) No, that is wrong; the RS232 is converted to TTL at the serial interface board, so you do have TTL on the phone cord. In any event, I would guess that 50 ft. would not be a problem; we're talking about 9600 baud here which is pretty slow. BTW, (...) (28 years ago, 4-Mar-97, to lugnet.robotics.handyboard)
