- Connect the USB cable to the PC and install the driver, if necessary. Do not connect the cable to the transmitter yet.
- Open the terminal program and open a connection to the corresponding COM port using the default settings 19200, 8, N, 1, no flow control.
Keep the Enter key pressed down and connect the other end of the USB cable to the transmitter. This will cause the transmitter to start in serial mode, using the
default serial settings.
You can now use the transmitter with the terminal program.
To prevent Modbus mode from being restored on the next power-up, select a different serial mode with the smode command.
