To RHT system functioned except the basic elements of sensors and applications on your computer, we need additional components that are typically related to the RS485 communication pathways.

Since the standard version has no personal computers RS485 port (port) certainly we’ll need an adapter for RS485. Earlier they used to know and RS232/RS485 adapters but now increasingly rare to encounter computers RS232 ports so it is best to use USB/RS485 adapters. We need as many adapters as RS485 ports used in the application (one port can serve a maximum of 16 sensors).
