Figure 3-29 RS-485 Network Connection
If there are multiple inverters in the RS-485 network, the selector switch S201 of the last inverter in the daisy-chain
should be in ON position, to have the 120Ω terminal resistor enabled. The selector switch S201 of all other inverters
should be in the OFF position to disable the terminal resistor.

NOTICE!
Ethernet Only Connection:
The PVI 25TL-480-R inverter only supports RS485 connections to a 3rd party DAS.
The PVI 25TL-480-R inverters can be connected to an external Data Acquisition System (DAS) via an RS-485 shielded
twisted pair serial connection as shown in Figure 3-31. These inverters can communicate with an external monitoring
system via the standard Modbus RTU protocol.
