Section 6. Data Communications
Optional RS-232 Communications Port
The DS7100 can be equipped with an optional RS-232 communications port. If
this option has been installed, the RS-232 connection is located on the left side
of the indicator housing. An RS-232 cable is included with the option. Insert the
headphone jack style connector into the receptacle on the indicator housing and
connect the 9-pin connector to your computer or printer.
Note: This option will reduce battery life.
Basic understanding of RS-232 data communications is needed when setting up
the DS7100 to communicate with a printer or PC. When setting up an RS-232
communications system, there are two concerns which affect the configuration of
that system. These are:
Baud Rate
Data Bits and Parity
The baud rate determines how fast the data is sent from the scale. The sending
and receiving units must be set to the same baud settings. The typical value is
9600.
The DS7100 is factory set for eight bits, no parity and one stop bit also known as
8n1. The receiving units must be set to 8n1 for proper communications.
Optional USB Communications Port
The D7100 can be equipped with an optional USB communications port. If this
option has been installed, the USB connection is located on the left side of the
indicator housing. A USB cable is included with the option. Follow the
instructions included with the option to install all necessary drivers.
Once the USB driver is installed on your PC, insert the USB connector into the
receptacle on the indicator housing and connect the other end of the cable to
your computer.
Remote Scale Commands
The scale will respond to the following single letter ASCII commands.
W
Initiates transmission of current weight data (if in motion, scale will
wait until stable, then print)
U
Changes the displayed weight units.
Z
Zeroes the scale (if in motion, scale will wait until stable, then zero)
