Arri mini LF Genlock via TC

[vins]

Hi all, has anybody successfully Genlocked the Arri mini LF or the Alexa LF from the external timecode source (via Sensor - Genlock - TC In) using something other than Ambient or tentacle sync timecode generators? 
 

I’m trying to use my Betso TCX 2+ but I am getting Genlock errors flash up on the camera multiple times during the day and occasionally the 1st AC loses picture. 

 

I have swapped to an Ambient system & all appears fine.

 

Thanks

I'm pretty sure the Alexa LF, like the Alexa, can't Genlock at all. I looked into this last year when I was about to shoot an Opera with three of them (covid-cancelled a few days before). Apart from that - I've only used Ambient on Minis when genlocking from TC, so can't contribute anything useful - but maybe measure the level the Betso is outputting vs the Ambient that works - it might be lower or higher than the Arri can lock onto.

Yes, Alexa mini LF is capable of syncing using Genlock IN BNC connector OR via TC in LEMO. If you see GEN lighting amber and/or image disappearing for 1-2 seconds it means that camera looses sync and do a re-sync. There are many reasons for this to happen including bad cables, generator malfunction etc. 

As of my experience with Ambient devices, Alexa LF performs perfectly
