1.2 Connection Examples

The following examples show how to connect using a PC / laptop without a built-in RS-232 COM port.

1.2.1 Using a USB-to-RS-232 Converter

Most standard USB-to-RS-232 converters come with a DB-9 male-type connector. Because the connector on the
dispenser is also a DB-9 male-type connector, you can use a DB-9 female-to-female adapter (gender changer) to
make the RS-232 connection.
