I'd like to see etherCON connections on the revision of the RM32AI and CS18AI hardware. RJ45 connectors are rubbish, the little cable clips always break. I will only use shielded CAT5e cables with etherCON connectors. The RJ45 ports make the RM32AI and CS18AI look cheap.
The RM32AI really needs an etherCON port at the front. The rear RJ45 port is very inconvenient for connecting my CS18AI every week. I understand it's part of the option card, and I can see why a rear connection would be handy if you had a little MOTU AVB switch. However, if you have a larger rack mounted switch, or you're on the road, a connection at the front would be much more convenient. Assuming you have designed the option card slot with a few spare connections, you could easily use these to wire in a etherCON connection at the front. This connection could then be used with either a Dante or AVB card. This wouldn't require an internal network switch, Ethernet will allow two connections on the one port. Obviously only one connection can be used at a time, but if two connections were inadvertently made it will just create network packet collisions, which is what Ethernet was designed to handle. If this can't be done due to the design of the option card, even a little RJ45 patch panel at the rear to an etherCON port on the front would solve the problem.
There really is no reason the CS18AI doesn't have an etherCON connector. They work with either CAT5 CAT6 or etherCON cables.
