CHAPTER 4 TESTING
4.6 COMMUNICATION TEST
The Trooper Scale and Trooper Count Scale each contain a communication port for RS232 protocol
communications. The RS232 Interface is a bi-directional interface that enables the scale to communicate
with a printer or computer equipped with an RS232 serial port. After the scale has been repaired and
calibrated and all menu functions operate normally, the communication function between the scale and
a computer has to be checked.
For this test, you will require a PC computer with communication capabilities such as a Hyper-Terminal
or a Terminal program that allows setting of communication parameters and an Ohaus RS-232 Cable
P/N 80500433, IBM-PC -9 pin or a standard null modem cable.
The RS232 Interface in the Trooper Scale and Trooper Count Scale can have its performance monitored
using an external printer or computer connected to the scale. It is preferable to use a computer so commands
can be sent to the scale to verify operation.
4.6.1 Setting Trooper Scale Print Menu
The Trooper Scale Print menu provides communication parameters which can be set to accommodate
external printers or computers. It contains the following submenus:
Reset, Baud Rate, Parity Bit, Data
Length, Stop Bits, Auto Print, Interval, Stable, and save settings
which enable you to program RS232 port
parameters.
Set the Trooper Scale print menu to factory settings which should be: Baud rate=2400, Parity Bit=None,
Data Length=7, Stop Bits=2, Auto print=Off, Interval=1 and Stable=Off. Save these settings.
4.6.2 Setting Trooper Count Scale Print Menu
The Trooper Count Scale also contains a print menu with the following submenus: Baud Rate, Data Length,
Parity Bit, Print Part No., Print Count, Print APW, Print Net, Print Tare, Print Total PCS, Print Gross, print
on Stable, Print Header and Print Style.
Set the Trooper Count Scale Print menu to factory settings which should be: Baud Rate=2400, Data
Length=7, Parity Bit=None, Print Part No.=Off, Print Count=On, Print APW=On, Print Net=On, Print
Tare=Off, Print Total PCS=On, Print Gross=Off, Print on Stable=Off, Print Header=Off and Print Style=Col.
