Depending upon the amount of telemetry devices you wish to connect, determines whether you use a regular Duplex Rx or a Rex Rx. As Tomas indicated, you use a single wire on the EX Bus output of the Rx. All channels can be configured to appear on the EX Bus. Furthermore, you can also use the extra Rx channels (other than the EX Bus port) for any other non-Spirit connections that you might wish.
I used a Jeti R3 Rx with my Spirit Pro; one of the channels configured (using Jeti Tx Device Explorer) to EX Bus, and the other two channels to control other devices not of interest to the Spirit Pro.
The trick is to assign the channels that the Spirit requires using the Device Explorer "Receiver Output" screen.
For my latest project, an Extreme Flight 65" Turbo Bushmaster (AKA Bushbaby), I switched to an Rex 7 as it is the smallest Rex Rx available in the United States (FCC certification.) I did this because I want several sensors to report back via the EXT port(s). The R3 EX Bus port is the "Ext" port, so no external telemetry is available; hence the Rex Rx.
EX Bus will allow as many channels as the Tx can support, but the Spirit in "Aero" mode, requires seven, at most (if using a channel for sub trim setting.)
I believe that Tomas provides the appropriate ".bin" file to Jeti and that is available for download. I have not had any problems interfacing with my Spirit Pro via my Jeti Tx (DC-24 and DS-14.)

Hi everybody
A can of niews, Afterwords you buy a R9, the all works perfectly!
Thank you for your advice, for longer use against my helicopter ...
I copy a file in .bin Jeti my DS14 and great BUGG, the RX does not work at all!
The dialogue does not look easy in case of trouble in Jeti, although unfortunately ....
I apparently expect a mail from an engineer at Jeti will be seen in time.
