Role of Neutrik etherCON
The Role of the Neutrik etherCON connector
There was a thread on the Behringer forum initiated by Gary Higgins (Data cable part 471 question 91) questioning the role and importance of the shielded cable and the Neutrik etherCON cable carriers (end covers) for the X32 AES50 digital snake. The latter (Neutrik etherCON) was further pursued by Gary and Anthony Martin by asking Neutrik specific questions. The end result was a very informative response, which can be seen on post #58.
The following is Anthony's summary.
- In assembly of the NE8MC & NE8MC-1 etherCON carriers, removal of the tab on the RJ45 plug is to ensure that the RJ45 plug does not get stuck in whichever receiving jack it is being plugged into. It is strictly a mechanical issue, not electrical.
- The assembly instructions for the NE8MC and NE8MC-1 etherCON carriers (Step F, Special version) refers to an RJ45 plug that is used in some European countries and is not used in the United States. These instructions are being re-written to remove ambiguity.
- NE8MC* and NE8MC-1* will make an electrical connection to a shielded RJ45. They will not make an electrical connection to an unshielded RJ45. This electrical connection to a shielded RJ45 can improve the rejection of electrical interference: besides the ground path from the shielded RJ45 through the etherCON chassis connector, a ground path is also established through the etherCON cable carrier to the chassis.
- The ability of the etherCON carrier's metal housing to reject electrical interference even for non-shielded RJ45s is a benefit, albeit one which typically does not make a critical difference between an electrically stable or an electrically unstable connection.
- Additionally, the rugged, locking mechanism of Neutrik’s etherCON cable carriers offers a clear mechanical advantage versus using a standard RJ45 connection. This mechanical advantage includes an increase in mating cycles of approximately ten times versus a standard RJ45. This increase is due to the etherCON housing performing the mechanical alignment rather than the RJ45 having to wiggle in and out of position with each mating cycle. This increases the life of the RJ45.
Please have a look at this. This presents how etherconn electrical connection affects connection stability in environments where ESD can happen.
