Page 9: Tr2-A And Tr2-B Hardware Differences
TR2 Catalogue User Manual 0089002 4. TR2-A and TR2-B Hardware differences The only difference between TR2-A and TR2-B is the supply voltage required. • TR2-A requires 5V • TR2-B requires 10V to 24V A resistor fitted to the board can be interrogated by the software to determine if it’s a TR2-A or TR2- B configuration. -

TR2 Serial RS232 Please note: There is comprehensive coverage of text-based serial comms in document:- 0084789.docm - TR2 Catalogue Text-Based Communications Specification 6.1. The basics • TR2 can communicate over RS232 at a fixed baud-rate of 115200, 8 data bits, No Parity and 1 stop bit. -
Page 13: Installing Drivers
For CAN you can use your preferred CAN controller. The PCAN-USB is quoted here as it is the only CAN device that will work with the Flintec Device Configurator App (FDC). The easiest connection is by USB-CDC as it uses a standard cable. -
Page 14: Calibrate The Tr2 With A Pc Running Fdc (Flintec Device Configurator)
10. Calibrate the TR2 with a PC running FDC (Flintec Device Configurator) The Flintec Device Configurator is an application that allows the user to set-up and calibrate the TR2 with a user-friendly graphical user interface (GUI). Whether connected to the TR2 by R232, USB-CDC or CAN the GUI looks the same. -

Here we are going to use a Terminal and the text-based commands to perform the same calibration. Though PC Terminal programs such as HyperTerm, TeraTerm and PuTTY can do the job the FDC has a handy ‘Terminal’... -

Page 26: Tr2 Can Tabs
TR2 Catalogue User Manual 0089002 Figure 11- TR2 selected for CAN operation Note: To connect another TR2 using CAN would require another PCAN-USB adaptor. 12.6.1. TR2 CAN Tabs Once connected the Weighing, TR2 Set-up, Save/Restore Settings and Terminal tabs are active. If you are familiar with using TR2 over Serial you will notice that apart from the Terminal tab, all the controls on the tabs are the same and the GUI is very familiar. -
Page 27: Fdc Can Terminal
TR2 Catalogue User Manual 0089002 12.7. FDC CAN Terminal Whilst it is easy to set up and calibrate the TR2 from the TR2 Set-up tab, we are going to use the TR2 CAN Terminal tab to calibrate the TR2. The reason for this is so the user can get a good idea of the data that goes back and fore. Not all TR2 users are going to use the TR2 connected to a PC or require the FDC for their project. -

TR2 Catalogue User Manual 0089002 13. TR2 I2C See document 0087552.docm - TR2 Catalogue I2C Bus Communications Specification for a fuller description of using TR2 over I2C. 13.1. TR2 I2C Overview • The TR2 will operate in slave mode, meaning that the master ECU will define the clock speed, though it is assumed that this will be around 20 kHz. -
Page 33: Engineering Mode
TR2 Catalogue User Manual 0089002 14. Engineering Mode When requesting Net, Gross or Tare Weight the reading is to 1 decimal place, but with the decimal place always set to 0. Therefore a TR2 calibrated to weigh grams with 108.1g on the load-cell will show 108.0. However, if Engineering Mode is activated the decimal place becomes valid, as shown below. -
Page 34: Tr2 Tilt Sensing
TR2 Catalogue User Manual 0089002 15. TR2 Tilt Sensing 15.1. Overview When weighing with a load-cell it is important that the load-cell is kept level so that the reading is accurate. If the load-cell is tilted then the weight registered will not be as accurate. This may not be a problem for small angles of tilt but for larger angles it could give unacceptable readings. -
Page 35: Tilt Commands
TR2 Catalogue User Manual 0089002 In an ideal situation we would see: • X and Y axis showing approx. 0 counts • Z axis is approx. +1023 counts. • PCB now placed upside down. Z axis is approx. -1023 counts. The best way to see the tilt feature in action is using the FDC application on the TR2 Set-up Tab. -

Page 37: Tr2 Gravity Compensation
TR2 Catalogue User Manual 0089002 16. TR2 Gravity Compensation 16.1. Overview Gravity Compensation is usually required when a scale is calibrated in one location (say the factory where it was manufactured) and then moved to the customer location. If the gravity values between the factory and customer location are different then the weight seen on the scale maybe higher or lower than expected. -
