Troubleshooting an O3 Hub
The O3 Hub is not communicating
l
Check that the O3 Hub has EnOcean capability (the model name must end in "E8" or "E9")
and is communicating over the correct frequency (868 MHz for O3-HUB-02-E8 models, 902
MHz for O3-HUB-02-E9 models).
l
Confirm power for the O3-DIN controller and the O3 Hub. The Status LED on the O3-DIN
controller and the Power LED on the CON-ENOC should both be green.
l
Check that the O3 Hub is wired to the NET3 (O3BUS) port on the O3-DIN controller.
l
Check that the O3BUS network is terminated at both ends. If the O3-DIN controller is at
the end of a segment, and doesn’t have an on-board termination switch, you must install a
120 Ω termination resistor at the NET3 port. If the O3 DIN controller is in the middle of a
segment, you must enable termination in the O3 Hubs at both ends of the segment.
l
Check that the object BV30s030 (“Enable EnOcean”) is created and commanded to On,
where s is the O3 Hub's rotary switch address in the range 2 to 9.
l
Check that the CANbus protocol was selected and activated on the NP3 object and confirm
that the Out of Service field is unchecked.
Communications are unreliable
l
Check that the O3BUS network is terminated at both ends.
l
Check the overall send and receive packet counts. If necessary, create the Total Receive,
Total Receive Error, Total Send, and Total Send Error objects.
l
Use a packet sniffer such as DolphinView to detect devices broadcasting excess packets.
l
Stop the excess broadcasting and reduce the traffic to normal levels. The LED for the NET3
port on the O3 DIN controller should begin flashing green again within a minute after the
traffic levels return to normal.
