I bought a used TRON with a kontronik kolibri. It has already installed a telemetry cable. But the previous owner flew V-bar control

Does my Spirit need a new cable for telemetry connection. I can't get anything on my DS12 screen. I programmed the Kolibri for jeti telemetry, and in the spirit I chose the Telme protocol

The cable I use now has ground in the middle pin and signal in the left pin
Is this the right connection, or do I need another pinorder

Not sure on the cable you have but this is what you need 'https://store.spirit-system.com/en/accessories/47-telemkontronikv2-cable.html'
Set telemetry to 'kontronik' ( 1 beep )
