connected to a single chain/bus. The humidifiers should be the same type but do not need to
be the same capacity. For example it is not recommended to have an NHTC and a GSTC as part
of the same chain, but it is acceptable to have an NHTC-200 and an NHTC-30 as part of the
same chain. Connecting additional non-Condair equipment into a Modbus chain is possible;
however it is important to ensure that all devices are operating with identical baud rate, parity,
and stop bits, and that each device has a unique Modbus address.
