SECTION 12 – BAR CODE
The Bar Code features of the 9750A allow the user to add scanned data to weight readings and trigger transmis-
sions directly into RF connected computers. In combination with the Data Logging features, bar code scans can
trigger data storage for uploading later.
Bar Code data is directed into text fi elds under user control. Four strings, K1 (Bar Code 1), K2 (Bar Code 2), K3
(Bar Code 3), and K4 (Bar Code 4) are sized to accept up to 64 bytes. In addition the bar code can be directed
into ID Code strings 1 and 2 (20 bytes each) through the use of the function keys. Any string that can be entered
via the keyboard can also be input via the bar code scanner. This degree of versatility allows such activities as
operator ID, customer ID, product ID, etc., to be input via bar codes.
The MSI-9750A will interface directly to Bar Code scanners that use standard RS-232 output data. Power is
supplied on pin 9 of the serial connector. The 9750A supplies a variable voltage output of 6 to 9 volts that is the
switched output of the battery. Therefore a suitable bar code scanner must accept voltage over the stated range.
The voltage output can be supplied as a regulated voltage (3.3 to 5V) by special order. Contact MSI for informa-
tion on suitable scanners for your application.
BAR CODE SETUP MENU
The Bar Code Setup Menu is used to designate how Bar Code data is handled and sets minimum data size for
each type of Bar Code string. Typically a function key is pressed to designate where the data is to go, then the Bar
Code is scanned. By turning “AutoStart” on, any data coming in will go automatically into the Bar Code 1 buffer
unless a bar code designated function key is pressed fi rst. The typical operation will use Bar Code 1 for data that
is scanned often, and designate function keys for additional data input. With AutoStart on hands free operation can
be achieved just using the Bar Code scanner to initiate weight events with included Bar Code data. The Comm
Port Setup Menu is used in conjunction with the Bar Code Menu to trigger remote printing/data storage events.
