RS232 INTERFACE

Certain models of Scout

II

balances are equipped with a bi-directional RS232

compatible interface for communication with printers and computers. When the

balance is connected directly to a printer, displayed data can be output at any time

by using the Auto Print feature.

NOTE: The AC Adapter is recommended to power the balance when the RS232

interface is used.

Connecting the balance to a computer enables you to operate the balance from

the computer, as well as receive data such as displayed weight and weighing

mode. The following sections describe the hardware and output signal formats

provided with the balance.

Hardware

On the rear of the balance, a 9-pin subminia-

ture “D” connector is provided for interfacing to

other devices. The pinout and pin connections

are shown in the adjacent illustration.

The balance will not output any data unless

pin 5 (CTS) is held in an ON state (+3 to +15 V

dc). Interfaces not utilizing the CTS handshake

may tie pin 5 to pin 6 to defeat it.
