Kinefinity sync

Trying to run external timecode on a Kinefinity MAVO LF through the Kineback W TC port, without any success. I am configuring the Tentacle Sync for the camera as a Slave, with the Master set to a Zoom F6. I’m having no issues with the Zoom or syncing the two Tentacles, I just cannot manage to change the timecode on the MAVO.
