2.3 RS485 network communication.
Another type of network communication is the RS485 communication using two-wire transmission path. To
achieve this kind of data exchange, the PSU should be equipped with the additional RS485 TTL "INTR" interface,
converting data from the PSU into the RS485 standard and the USB-RS485 "INTUR" interface, converting data
from the RS485 network to the USB. Offered interfaces are galvanically isolated and protected against surges.

2.4 USB-TTL communication.
If the power supply does not support any of the above networks, use the USB-TTL interface "INTU" to
access the configuration parameters and operation history. This interface enables the connection between the
computer and the PSU and is recognized by the operating system as a virtual COM port.
