3.18 Communications
• The Communications tab page can be used to select a COM port of your PC
to talk to the HR-4P unit. Once, the preferred COM port is selected, pressing
the Connect button either in this tab page or on the left of the Main screen to
make a serial connection.
• Since the HR-4P’s serial port communicates at a fix baud rate of 19200, no
parity, 1 stop bit, and 8 data bits, those drop-down selections will be disabled.
The COM port is the only selection that needs to be set as shown in Figure 16.
