Troubleshooting
Fast, Easy Answers...
Connecting two devices using RS-232.
Usually inputs are connected to inputs
and outputs to outputs. People don’t realize
that there are two types of RS-232 ports,
DTE and DCE type, and that the signal
names and pin numbers are the same, but
signal flow is opposite. The pin labeled
Tx can be input, and Rx can be output.
The two ports types are complementary.
The Output signals on a DTE port are Inputs
to a DCE port, and Output signals on a DCE port
are Inputs to a DTE port. The signal names match
each other and connect pin for pin.
