“Connecting the DSC-20 to your computers serial port”. If your test failed,
follow the troubleshooting steps A through G that follows.
TROUBLESHOOTING
ABuild a loop-back “TESTER” by purchasing a “FEMALE” 9 pin D-sub solder cup
connector (Radio Shack, CompUSA, Local Electronic Store, etc).
B Solder a jumper between pins 2 & 3.
CTry typing on the keyboard with nothing connected to the computer’s com port.
You shouldn’t see any characters. If you do, the “ECHO typed characters
locally” is checked (ON)” in the ASCII settings in HyperTerminal. Turn this OFF
(Uncheck) and retest Step C.
