be the same capacity. For example it is not recommended to have an NHTC and a GSTC as part

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.
