9.1 Bar Code Input
Bar code input is available using either a laser scanner or a wand (or pen) scanner. The laser scanner allows
non-contact, instantaneous, accurate input of unit weight, tare weight, and ID code.
Scanners connect to the circular DIN connector marked “bar code” in the rear of the scale. The pen reader is
an economical way to use the accuracy and speed of bar code data input when contact scanning is available.
Be sure to verify the correct settings on SPEC17, bits 1 and 0.
9.2 RS-232 Communications Port
The bi-directional RS-232 port can be used to communicate with a computer for database handling. This is
the 25-pin rectangular connector located in the rear of the scale. The following sections describe RS-232
specifications, configurations, and installation.
Notes:
Custom software may be available to fit your needs. See your RLWS distributor for information.
