Possible Cause/Suggested Fix
• Cable is bad or disconnected
• Cables going to wrong port (i.e., switched TO ABOVE and
TO BELOW)
• Transmitter from device above or below is bad, check
faults for that device.
• Receiver on board is bad – replace device
• Cable connecting two devices could be flip- flopped (i.e.,
gray wire goes from pin 1 on one end to pin 8 on the other
end). Disconnect cable, and if fault changes to Rx Fault, the
problem is the cable.
