I know the max. distance between the controller and differential receivers is 250'. But what is the maximum length of Cat5 you can run between your computer and the F48? Assuming that would also be 250'?

Can't wait for the WiFi feature to be available!

The controller-to-receiver connection is RS485 and should be able to go a lot farther than 250
The controller-to-computer connection is ETHERNET and is limited to 100 meters port-to-port.  You can extend this distance with an Ethernet switch or router in the middle

RS-485 spec is 4000 feet total loop if it's true 485.  So I would assume that from each port to the receiver you could have 4000 feet of cable, though I could be talking out of my butt here.

Industrial rs485 may go that far (shielded cabling) but you could get likely 1000ft on cat5e. I easily did 300 as a test though my property is <100ft in any direction or route.

As a test of distance for RS485, last year we hooked up a whole box (1000') of Cat 5e - still in the box so it was still coiled (a concern for some wireheads) - and it did just fine.


As far as from the computer to the controller, since it is Ethernet based - 100 meters (328 feet) is the specification.


From a pixel output to the first pixel has been debated here for some time.  There are some devices where the first pixel must be in the range of 10 feet.  There are other devices where there has been as much as 65 feet (reliably). 


I guess that is why we are DIYC.  Do It Yourself and C.  :)
