measurement data is transmitted to the Victron GX device with the single interface cable.
Each model solar irradiance sensor within Si-RS485 series has a different capability with regards to
external sensors (or comes with an external sensor pre-wired), so carefully consider any future
desires/requirements before initial purchase.
It is also possible to connect an independent

temperature') directly to the Victron GX device, without a solar irradiance sensor or in addition to one.

1.10.2 Operation

The IMT Si-RS485 series solar irradiance sensors operate using RS485 electrical interface and
RTU communication protocol.
The required interface software is pre-installed within the Venus OS, however the Victron GX device
must be running recent firmware - FW v2.40 is the minimum requirement.
Physical connection to the Victron GX device is via USB port and requires a
interface cable.
A suitable external DC power source (12 to 28 VDC) is also required - the sensor is NOT powered via
USB.
