Additional Information for Networked Systems
For large systems, we recommend testing small sub-systems before completing full-scale
installation.
In some systems additional RS485 devices may be needed to resolve offsets in ground voltage
and ambient noise. For large installations, consult AirCare Automation for advice on RS485
network configuration.
