HoTT Telemetry
Graupner HoTT ESC has telemetry feature built-in in the Programming port. This allows telemetry data transmission to the unit. To allow the ESC telemetry, it is necessary to have updated ESC firmware to a more recent.
It is important to flash firmware with Sensor Emulation called EAM - Electric Air Module.

It is very important to modify the cable correctly, otherwise permanent damage of the Spirit unit will occur!
1.1 Cable modification
Extremely important is the following Modification of the JST-Servo adapter cable. It is required to unplug or cut RED wire of the adapter as displayed at the photo.
2 Interfacing
Connect the Telemetry cable to the primary Spektrum satellite port (SAT1) in the unit - apply for Spirit 2, Spirit RS, Spirit Pro, Spirit GT, Spirit GTR.
Smaller Spirit units will utilize the one native Spektrum satellite port (SAT) - apply for μSpirit and Spirit 1.
Servo connector of the Telem UNI cable should be connected to the ESC - telemetry/programming port.
