5.2 RS232 Interface
Explorer balances are equipped with a bi-directional
RS232 compatible interface f or communication with
printers and computers. When the balance is connected
directly to a printer, displa y ed data can be output at any
time by simply pressing PRINT, or b y using the Auto Print
feature.
Connecting the balance to a computer enables you to
operate the balance from the computer, as w ell as
receive data such as display ed w eight, weighing mode ,
stability status, etc.
The following sections describe the hardware and
software provided with the balance
Hardware
On the side of the balance, the left-hand, 9-pin male
subminiature “D” connector is provided for interfacing to
other devices. The pinout and pin connections are sho wn
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.
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.
The output format is illustrated in the RS232 command
table which follows .
RS232 Connection
Side of Balance
RS232 Commands
All communication is accomplished using standard ASCII
format. Characters sho wn in the following table are
acknowledged by the balance. Inv alid command response "ES" error indicates the balance has not recognized the command. Commands sent to the balance
must be terminated with a carriage return (CR) or
carriage return-line line feed (CRLF). F or example, a tare
command should appear as shown in the adjacent
diagram. Data output b y the balance is alw ays terminated
with a carriage return - line feed (CRLF).
