12. HUMIDIFIER CONTROL VIA NETWORK
The variables shown in the list are a set of all the internal variables.
DO NOT CONFIGURE ANY VARIABLES THAT ARE NOT SHOWN IN THE TABLE,
OTHERWISE HUMIDIFIER OPERATION MAY BE AFFECTED.
The serial connection (M11) is configured by default with the following parameters:
- Address 1
- Baud rate 19200 bps
- Frame 8,N,2
