Yaesu GS5500 External Connector

Hi to all!!! someone who has the same rotor (YAesu GS5500), can you confirm the voltage from the pins 1 and 6??? in the manual says that the voltaje will be between 2 and 4,5 VCC, but in my control has 15 VCC (?¿?¿?¿)

Maybe someone has the same rotor and could meassure it.

Thanks
