- R.3 - Kordz R.3 HDMI 2.0 2160p 18GBps

Question - what's the difference between the fast flash on the Green light next to the HDBaseT port and a slow flash?


What it appears to point to is that individually, all the products are ok, they work fine, but:

- Using the Ultra extender kit into a receiver gives no picture

- Using the Pro Extender kit in place of the Ultra gives a picture

- Using a combination or ProTX and Ultra RX gives picture

- Using older cables suck


Interestingly, using your HDMI 4kDS unit to downscale the signal out of the Ultra extender kit before going into the Arcam produces a solid HDBaseT link, but no picture. 


Anyway I do need some sort of solution for the Ultra extender kit into a Receiver, as that's the exact set up required in this solution. 


Solution: Pulse-EIGHT recommend firmware upgrade


Would you be able to update the Ultra extender set, the instructions are in this link
