Arri RF-2400 Radio Module and a Cmotion RF Motor

I'm potentially thinking of switching over from my cPRO+ to a Hi-5. I've been looking over the radio modules and am a little confused by the differences between the RF-EMIP and the RF-2400. If anyone has a good explanation of why one over the other or knows a good video describing them I'd appreciate it. Also, am I wrong in thinking that the RF-2400 would work with a Cmotion RF motor or is the red ring around the antenna a mere design choice and not indicative of it working on the same red coded radio as Cmotion? It would great if I didn't have to buy another RF motor.

Yes, you're correct. cforce mini RF has an internal EMIP radio, so you need an RF-EMIP in your Hi-5 or ZMU-4. WCU-4 and SXU-1 also have an internal EMIP module, so you can use any three of those hand units all together in one network to control up to 4 lens axis. If you want to use the RF-2400 or RF-900 modules then you need a RIA-1 on the camera, or actually a ZMU-4 on the camera could do the same thing in host mode (but that's a bit of a niche situation).
