Are here some Hytera Radio Specialist?

[Lord of nothing]

Hi
Long story short I own some PD6 who support Variouse Services with an old but working Hytera "Demo" Software. One if them is Data Transfer between 2 Radios!
Why is that important? Well since in an Emergency Case People should be able just with an Handheld Radio (in an Pouch) and an Tablet be able to access Data.
The Radio support other thinks via the Cable to. Sadly I found no way to push Audio Digital from the Radio to the Tablet. Are there any ways or do I need to "Digitise" the Audio again? I found an Pinout but I am not sure if Pins are used for different function twice (like Voice and Data).
Thanks!
