7. USING
After property connection according to section above you can start using the converter. During data transmission LEDs should blink
and they indicate appropriately:
LED
Description
Rx (yellow)
data reception via ADA-I9141 converter from RS485/RS422 port.
Tx (red)
data transmission from ADA-I9141 converter via RS485/RS422 port.
7.1. BAUD RATE SELECTION FOR PROFIBUS COM PORT
For setting correct Profibus baud rate (after installation “Virtual Port” driver for Profibus) in application using virtual port COM follow
table below.
Set baud rate [bps]
Actual baud rate [bps]
Profibus
