5.1. During Software Installation
The BCom Data_Logger and Data_Indicator software is designed and tested to run
under the following Microsoft operating systems:
• Windows 7
• Windows 8.x
• Windows 10
Please refer to chapter 2.6 on page 2.6 for requirements to the personal computer
needed for the software.
If a “Not connected” message appears in the event window after you have started
“BCom Data_Logger”, the following steps may fix the problem in case the RS-485
converter is used:
• Is the RS-485 converter’s green power-LED on? Check the power supply.
• Is the wiring of the RS-485 interface reversed (connection A and B).
This is the most common cause of error!
• Is the RS-485 converter connected to the correct COM port? If connected
correctly, the transmit LED (TX) (Fig. 5.1) should blink after measurement
start to indicate that computer is sending data.
• If the connection is established, this is confirmed by a “Connected” message
in the event window. (Fig. 5.2)
