Status Description
Indicates that the PC has enabled RS-485 transmission.
This means that the RS-485 driver has been enabled allowing
the convertor to drive the RS-485 line to the remote system.
Indicates that the remote RS-485 system is transmitting data
to the PC through the convertor. The LED will flash when
data is being transmitted.
PC is transmitting data to the remote RS-485 system.
The LED will flash when data is being transmitted.
