RED GEMINI shoots on its own

[Carlo Musco]

Hi guys,
I'm having quite a serious problem with the GEMINI. It happens that, usually beginning of shoot-day or when changing mags, when switching on the camera something triggers it to roll. It starts rolling on its own and if I cut, it starts again. The only solution is to eject media and re-insert the mag again. Then it usually goes back to normal. Any ideas of what is causing this?

It's quite annoying cause I need to re-format a couple of times before it stops doing it.
I have 2x RED 120gb mags.

Thanks!

What's your entire setup like? Are you powering any third party accessories via the D tap port? Is your SSD bay securely seated/mounted on the camera?

This is my setup from the last shoot. I use all the D taps, respectively for Shinobi monitor, Teradek and Nucleus (missing in the pic)

Could be that your screen and wireless draw to much power and that makes camera behave odd. Seen that happen before. Test by feeding screen and other stufff from it own bat.

Do you have the Nucleus connected to the CTRL port?

[Aaron Lochert]

What Bjorn said. That's what I was trying to get at when asking what other accessories you were powering from that same D-Tap. The DSMC2 D-Tap is max 3.0 Amp draw, 11.5-17v.

The Nucleus-M is probably the biggest culprit for overdrawing power. Have you ever had it trigger an auto-record when the Nucleus motor hits a hard stop on the lens? I've seen that plenty of times before.

First and foremost see if WiFi is on.

But pretty much what others suggested from there.
