RS-232 connections
The RS-232 serial port can be connected to the serial port of a controller (i.e., personal
computer) using a straight through RS-232 cable terminated with DB-9 connectors.
Do
not use a null modem cable
. The serial port uses the transmit (TXD), receive (RXD), and
signal ground (GND) lines of the RS-232 standard. It does not use the hardware handshak-
ing lines CTS and RTS.

RS-232 interface connector
If your computer uses a DB-25 connector for the RS-232 interface, you will need a cable
or adapter with a DB-25 connector on one end and a DB-9 connector on the other, wired
straight through (not null modem).
provides pinout identification for the 9-pin
(DB-9) or 25-pin (DB-25) serial port connector on the computer (PC).
