Appendix A - Balance Connection; Appendix B - Pc Connection And Software Installation - Manostar Compulab 3 Manual De Operación

The following balances have been confirmed as compatible with
the COMPULAB 3. Other balances may work with the dispenser,
but have not been tested by Barnant Company.

The COMPULAB 3 provides communication to the balance
through a nine-pin male RS-232 DTE port on the back of the
control console. The COMPULAB 3 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 6 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 COMPULAB 3 provides communication to a personal
computer through a nine-pin female RS-232 DCE port on the
back of the control console. The COMPULAB 3 communicates
with software provided with the system to provide an alternative
user interface to access all the capabilities of the system. Figure
20 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 COMPULAB 3 Control Software can be used to program or
operate the dispensing system from a PC using the WINDOWS
