Looking for a little guidance on interfacing this Radio-Tone unit/cable with an XPR4350. This came with a 26pin cable, but Im concerned that other items in CPS need to be turned on/off. The intent is to interface this with Zello, which is purely vox controlled. Assuming they followed the Motorola pinout specs for the rear accessory port, what should I configure in the codeplug? Appreciate any help given.
