3.3.5. Serial Communication
When this feature is unlocked the torque tester sends out measurement data at the end of each torque test. When
a monitoring program use a handshaking (ASCII x) signal to receive data from the torque tester it also sends out the
measured torque and angle data real-time.
Make sure that your host computer is connected to the PLC, and running the Sure Torque data acquisition
software or a terminal emulation software. You also have to check the following settings in the configuration of the host
computer’s serial port: The data is in ASCII format with CR, LF Delimiter. Protocol: 56700 Baud, 8 Data bits, 1 stops,
no parity (see Figure 3-2, RS-232 Cable and Communication Parameters). Cable to PC Serial Port is optional.
DEFAULT COMMUNICATION PARAMETERS
1. BAUD RATE: 56700
2. PARITY: NO
3. DATA LENGTH: 8 BITS
4. STOP BITS: 1
Figure 3-2, RS-232 Cable and Communication Parameters.
ASCII communication strings:
Real-time: “111.1-2222CRLF”
Result: “ Applied Torque= 111.1/222.2 333333 Time: 44/44/44 55555555 66CRLF
Result: “ Release Torque= 111.1/222.2 333333 Time: 44/44/44 55555555 66CRLF
Result: “ Strip Torque= 111.1/222.2 333333 Time: 44/44/44 55555555 66CRLF
Etc…
The tester may be directly connected to a serial printer or using a serial to parallel adapter it is possible to connect
a parallel port printer, too. On customer request we also modify the communication protocol, to satisfy the
specifications required by the customer’s existing SPC software.
Today’s laptop computers are usually not equipped with serial ports. When you want to capture the measurement
data into a laptop, you can use almost any USB-Serial adapters. Our favorite is the ATEN-UC232A model.
3.3.5.1. Sure Torque Data Acquisition
Optional Microsoft Windows compatible software package for data collection from ST-LAB through the industry
standard RS-232 Port. (Port 2 RJ11 connector) If you have purchased this option, refer to the Appendix A in this
manual for details.
WARNING
If your Sure Torque ST-LAB Electronic Torque Tester is not running smoothly, or there is any doubt as to its
operational proficiency or proper production cycle, contact ST Customer Service at once:
3.3.5.2. Customisation of the communication string
Data string customisation and communication protocol setup is only available at Sure Torque Please make sure
that the data communication string and the serial port configuration is compatible with your system requirements.
