How can I change the pressure settings on my NETCOM? Establish communications with the dehydrator through the Ethernet interface (default IP address from the factory is 192.168.52.2) and navigate to the configuration page. Here you can change the low pressure alarm, low pressure limit, high limit target and high pressure alarm settings. You can also select between psig or mbar and small or large system settings.
