5. ACTIVATION
HUB can be powered after proper connection according to steps above.
If connection was made properly green LED PWR on front panel of HUB should light, if not check polarization of power connection.
During correctness data transition via the HUB the LEDs Tx and Rx should blinking.
5.1. SIGNALING LEDS
LED Description
PWR Signalling of Power Supply
RX Signalling of data receiving through HUB ADA-4044H from RS485/422 (RS485-OUT) port
TX Signalling of data transmitting from HUB ADA-4044H through RS485/422 (RS485-OUT) port
ATTENTION!
At baud rate above 38.4 kbps the LED's Tx, Rx will light weakly during data transmission.
5.2. TROUBLESHOOTING
Problem Solutions
PWR LED is not lights Check polarization and parameters of connected power supply.
Rx LED lights continuously
RS485(4W)/ RS422 network. Wrong polarization on R1+ / R1-, R2+ / R2-, change
polarization.
RS485(2W) network. Wrong polarization on A1/B1, A2/B2, A3/B3, A4/B4, change
polarization.
No transmission,
Tx LED is blinking
RS485(4W) / RS422 network. Check the correctness of connection according to section
INSTALLATION .
RS485(2W) network. Check the correctness of configuration setting according to section
CONFIGURATION .
