4.5. PROBLEMS
Problem
Solutions
PWR LED is not lights.
Check polarization and parameters of connected power supply.
Rx LED lights continuously
RS485(4W) /RS422 bus. Wrong polarization on Rx+, Rx- terminals. Change polarization.
RS485(2W) bus. Wrong polarization on Tx+/A, Tx-/B terminals. Change polarization.
No transmission,
Tx LED is blinking
RS485(4W) /RS422 bus. Check the correctness of connection to Tx, Rx terminals according
to chapter 3.
RS485(2W) bus. Check the correctness of configuration setting according to chapter 4.
