Ok, just when I think I've got this whole thing figured out I realized I don't. The more I try to research it the more confused I am getting. I bought a DECA broadbank converter thinking that was all I needed to get my HR21-700 and HR22-700 to work with MRV. I now realize I need a DECA unit to connect to my HR21-700 to the HR22-700 and to my network, since I can no longer just use ethernet and run it through my router. My questions is, if I were to just order a CCK-W would that simplify my setup? I don't need a wireless connection to the internet, I've got a network drop I can easily use for the network connectivity but by the time I buy all the parts I need this might just be the easiest way and suddenly the cost is pretty darn close.....if it will solve my problem of course. Thank you all for your help!
