Well I have some very good news to report. I got the correct Ranger 2304-USB, and I can confirm that the ATIK383L+ mono I have and the EFW2 both connect and work well with this device. My QHY5-II did work but was a little iffy.
Anyway, the Ranger2304-USB is good to run on 100m of Cat5e!!! (300ft plus!!) As I only need about 100ft to get to my astro shed, this is great news.
Icron, have been very helpful throughout, and this product is a great asset to the Astro community.
Now I just have to build my shed!
