2.3.2 RS232 Interface

Explorer Pro balances are equipped with a bidirectional RS232
compatible interface for communication with serial printers and
computers. When the balance is connected directly to a printer,
displayed data can be output at any time by simply pressing the
Print button, or by using the Auto Print feature. Connecting the
balance to a computer enables you to operate the balance from
the computer, as well as receive data such as displayed weight,
weighing mode, stability status, etc.

The following sections describe the hardware and software
provided with the balance

Hardware

On the rear of the balance, the right-hand, 9-pin male subminiature
“D” connector is provided for interfacing to other devices. The
pinout and pin connections are shown in the adjacent illustration.
Refer to paragraph 3.5.6 for setup.

The balance is equipped with hardware handshaking, it will not
output any data unless pin 5 (CTS) is held in a high state (+3 to
+15 V dc). Interfaces not utilizing the CTS handshake may tie pin
5 to pin 6 to defeat it.

Output Formats

Data output can be initiated in one of three ways: 1) By pressing
PRINT; 2) Using the Auto Print feature; 3) Sending a print
command (“P”) from a computer.

Additional information is located in Section 5, Technical Data
which contains the RS232 Command Table.
