The DIGI-STALTIC provides communication to the balance
through a nine-pin male RS-232 DTE port on the back of the
control console. The DIGI-STALTIC communicates at 9600 baud,
7 databits, 2 stop bits, odd parity. The balance must be set up to
communicate at that protocol and must be set up to measure in
grams. Table 7 shows pin connections and signals necessary for
the dispenser to communicate with the compatible balances.
NOTE: If a balance is being used for dispensing, the actual
weight of the finished dispense is communicated to the
controller. The controller displays the weight and, if
necessary, adjusts the calibration for the following
dispense.

APPENDIX B — PC CONNECTION AND SOFTWARE INSTALLATION
The DIGI-STALTIC provides communication to a personal
computer through a nine-pin female RS-232 DCE port on the
back of the control console. The DIGI-STALTIC communicates
with software provided with the system to provide an alternative
user interface to access all the capabilities of the system. Figure
17 shows pin connections and signals necessary for the
dispenser to communicate with the computer.
A complete description of the serial communication protocol can
be found on the enclosed CD-ROM (kit part number 77310-10).
The DIGI-STALTIC Control Software can be used to program or
operate the dispensing system from a PC using the WINDOWS
95/98 or WINDOWS NT

Software:
1. Insert the DIGI-STALTIC Control Software CD in the CD-
