Connect the HR-4P to the RS-232 port using a F/F Cross-Over DB9 cable (included in the package). For the unit to use its
RS-232 in programming and/or command input mode, you need to
slide the switch next to the serial connector to PRG mode. The LED
over the switch will start blinking.
Click the Communications tab to verify or change the
COM port selection. This setting will be remembered for
future use. The baud-rate in PRG mode (for use with GUI)
is fixed.
To open a serial connection to the unit, click the Connect button on the left side of the screen to attempt a
connection to the HR-4P. The button will automatically change and say Disconnect. There are also Connect and
Disconnect buttons on the Communications tab that perform the same functions.

If a connection was established between the software and the unit, the GUI main screen will update as
shown in Figure 2. Note that the bottom lower left of the screen will always show the current connection
status.
To close the serial connection, click the Disconnect button on the left side of the screen, or click the Disconnect
button in the Communications tab.
