The RS232 serial port lines are usually connected to a DB9 connector with the following
layout:

9.4.

5V UART Level Translation

If the OEM application uses a microcontroller with a serial port (UART) that works at a
voltage different from 2.8 – 3V, then a circuitry has to be provided to adapt the different
levels of the two set of signals. As for the RS232 translation there are a multitude of single
chip translators. For example a possible translator circuit for a 5V
TRANSMITTER/RECEIVER can be:

TIP:

Note that the TC7SZ07AE has open drain output; therefore the resistor R2 is mandatory.
