Pin 3 RxD
- The received data signal RxD
expects the standard asynchronous serial data
format. It will accept either CMOS level or true
RS-232 level signals. The figure below shows the
equivalent input circuit.
RxD Circuit
Pin Description
Pin 2 TxD
- The data output signal TxD obeys
standard serial asynchronous data formats, but
uses zero to five volts CMOS logic levels. It can
be described as CMOS level RS-232. The TxD
output circuit is shown in the figure below. It
will drive TTL, LSTTL, CMOS, HC, and HCT
inputs.
Connector
The standard connector is a 9 pin male D
connector. There is also an option for the cable
to have stripped and tinned wires.
