4.1. RS232 Serial Data Communication
This balance has a Bi-Directional RS232 port for communication with a PC. When connected to a computer,
the weight value can be sent to the computer and commands can be sent to the balance
Transfer Format: Asynchronous
Communication Protocol: 1 start bit, 8 data bits, 1 stop bit
Baud Rate: 600
ASCII Output:
1 2 3 4 5 6 7 8 9 10 11 12 13
Weight Data Unit
Example String: “0 0 0 1 2 3 4 5 c t _ _”
Meaning: 123.45ct (carats)
NOTE: The CD included with the balance is meant for demonstration purposes only. To install simply copy
the program files to your computer and launch Weight Display.exe. By default, the program listens for weight
data on serial port1.
4.2. Serial Number
When communicating with the balance from a PC, a serial number (from 1-100) is used to identify the
balance. By default, the serial number is 27. To change the serial number, press and hold the UNIT and MODE
buttons together until the display shows “No - ###” (### stands for the serial number). Tap the CAL button to
change the serial number from 1-100. Press the MODE button when you are finished.
4.3. Commands
The following commands can be sent to the balance:
serial no. + 70H Request weight data
serial no. + 71H Enter Calibration Mode
serial no. + 72H Enter Counting Mode
serial no. + 73H Change weighing unit
serial no. + 74H Tare the balance (zero)
4.4. Care & Maintenance
Please read all operating instructions carefully before use. Scales are precision instruments and should
always be handled with proper care. To ensure years of reliable service, keep these simple tips in mind:
• Do not exceed the scales maximum capacity. Overloading your scale can permanently damage it!
• Avoid exposure to extreme heat or cold. Scales perform best at normal room temperature. If temperatures
have changed dramatically, recalibration may be necessary.
• Allow your scale to warm up for three hours before performing initial calibration.
• Store your scale in a clean, dry location. Dust, dirt, and moisture can accumulate on the weighing sensors
