I have an outdoor rj45 ethernet coupler where 1 side of it has a flat ethernet cable plugged in. When I test the whole connection with ethernet cable tester the 2nd light is always off where the other 7 blink in unison on the tester. I confirmed the coupler is fine with other non flat cables. I get the same bad result with 2 different flat ethernet cables so I'm guessing it's something in the wiring of the flat cables? Suggestions Thanks

Does the coupler need an external adjustment to accept the flat cable? If it works fine with the others, it may lack an autosensing feature.

1. Check whether the lines on both sides of the coupler are of the same type? (cat5/cat6/cat7)

2. Check whether there is any problem with the wiring sequence of the cables used?
