RS485 / Modbus Adapter
The Modbus adapter is an optional device for the Power Factor Controller RVT which
enables the connection of the RVT to a RS485 Modbus system. The controller is
considered as a slave unit in the Modbus network.
Refer to the 2GCS214013A0050-RVT Modbus RS485 adapter-User guide for more
information on the RS485 Modbus Adapter.
GREEN
Be careful that the RS485 MODBUS ADAPTER is the one with a
text color
(3.3V power supply).
WHITE
The one with a
text color is reserved for the old model (5V power supply).
That means: the new Modbus adapter is not compatible to the old RVT; and the old
Modbus adapter cannot be connected to the new RVT (with touch screen).
