I have 3 MULTIPLUS II in parallel and can only get 2 to operate, whenever I connect a particular unit I get error 17.
The dc cables are all the same length and type and the RJ45 cables are all purchased and new. 2 units work fine in any position but the 3rd fails in any position. They are all running the same firmware (was 494 now 497, no change to behaviour)
Any ideas for what I can check next?
Cheers
Max
