Figure 8. Interface board
Perform the following start-up procedure for the GUI:
1. Connect the insulated PC interface board to the PC via the RS232 Interface cable and
to the thermostat board via the SCI Interface wire.
2. Connect the 230V/9V insulated power supply to the SCI interface board. First check
that the 230V/9V insulated power supply is correctly set: the Volt switch to the “9V”
position and the Polarity switch to the “Positive” position (
Figure 9 ).
3. In case of a problem, ensure that the “selected Serial Communication Port number”
(COM1 or COM2) in the options dialog box is correct.
4. In order to enable communication between the GUI software and the thermostat board,
it is necessary to push the “connected” button (“Connected” LED switch ON).
Note: Refer to the “Help” menu of the GUI software for more information.
