ultrasonic flowmeter integrates a USB communication interface and a complete
set of serial communication protocol. By using this serial communication link, one can
configure the flowmeter and acquire measurement results from a PC. The following steps must be
completed:
Install the USB driver on the PC. This will generate a virtual COM port for the flowmeter.
Connect the flowmeter to the PC through the USB cable provided with the flowmeter unit
Check the flowmeter COM port settings (Baud rate, parity, etc.)
Set up PC software, either Hyper Terminal or StufManager
TM
software
Now you can communicate with the flowmeter from the PC

eter to a PC
A standard USB cable is provided with your
NCM-603
unit. Just simply plug the cable to the
flowmeter USB port on one end and to the computer on the other end. Then, turn on the

COM port (VCOM).
Note:
you need to install the USB driver before connecting the USB cable.
6.3 Check the Flowmeter COM Port Settings
Go to menu window M62 to check the COM port settings on your flowmeter. Write down the baud
