Status Description

1

Red

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.

2

Yellow

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.
