Modbus and BACnet communication settings are configured with the DIP switches on the HMD65 component board (see Figure 1). In addition to the communication settings available through the DIP switches, you can configure certain Modbus and BACnet settings with Vaisala Insight PC software (requires Vaisala USB cable 219690).
