Page 4: Introduction
It measures ambient air temperature, relative humidity, barometric pressure, wind speed and direction and is capable of measuring rainfall, soil or other peripheral temperature and global irradiance. The PVmet-330 uses a 2-wire half duplex RS-485 serial port for Modbus RTU communication with a host. -
Page 5: Installation
By default the PVmet-330 is configured for operation in the Northern hemisphere. This only requires that the irradiance sensor faces due South. If the PVmet-330 is going to be used in the Southern hemisphere it must be mounted with the irradiance sensor facing North. -
Page 6: Connecting The Power Supply
Signal/Power Ground +VDC: External 10-30VDC Supply RS-485 is rated to 4,000 feet (1,200 m) at 90 kbps. The RS-485 port on the PVMET-330 is surge protected but not isolated. Connecting the Power Supply The weather station can either be powered from its own battery and solar panel or from an external power source (depending on model). -
Page 7: Unsupported Fields
The register map reserves registers for all combinations of sensors supported by the Rainwise stations. Not all will be available on any one system. Sensors/fields that are not supported will contain the value 0x8000. Some fields require the purchase of additional sensors. -

Page 9: Changing The Modbus Device Address
Changing the Modbus Device Address The Modbus device can be changed using the dipswitches 1 & 2 with the default position set to device address 60. Modbus Address Switch 1 Switch 2 Changing the Baud Rate The baud rate can be set to either 9600 or 19200. The default baud rate is 9600. Changing dipswitch 5 to the ON position will change the baud rate to 19200. -
