8.4.4 Recalling the factory configuration (“factory bootswitch” mode)
With the following procedure, PCOnet uses the default parameters instead of the ones specified
by the user. See the table of parameters and factory values in the section on Configuration. In
“factory bootswitch” mode, PCOnet does not save the recalled values, and consequently when
next restarted without pressing the button, PCOnet will again load the user settings. When
purchasing PCOnet, the user parameters are set to the factory configuration values.
With PCOnet OFF:
• Switch PCOnet on (i.e. switch on the pCO* controller with the PCOnet board inserted)
by pressing and holding the button for at least 20 seconds: the Status LED will flash
SLOWLY 3 times, red-off
• Release the button while the LED is flashing: after 3 red flashes, the LED comes on
green; the LED then confirms recognition of the button by flashing QUICKLY 3 times red-
off, and then comes on green again
Complete start-up of the PCOnet will take another 40 seconds, then the RS485 LED starts
flashing; only from this moment on can PCOnet be accessed via a remote connection.
With PCOnet already ON:
• Restart PCOnet (see above: Restarting PCOnet)
• After the restart procedure, follow the steps described above for PCOnet OFF
8.4.5 Configuration
Configuring the PCOnet parameters for correct communication over an MS/TP network:
• Connect PCOnet via RS485 to a computer: during configuration, the CAREL product code
CVSTDUMOR0 for USB ports can be used.
• Converters should not be used in the installation due to the large volume of data
transmitted across a complex BACnet™ network.
• Install the CAREL “BACset” configuration tool, available free-of-charge at ksa.carel.com.
Note: If the values of the PCOnet parameters are not suitable, communication with
BACnet may not be possible. To connect to PCOnet, restart PCOnet using “factory
bootswitch” mode (see the section on Operation - Pushbutton).
