The problem can only occur if the same V-mount battery is used to power both the camera and the monitor. If you use different batteries the order in which the devices are connected and turned On/Off does not matter at all.
This is incorrect. If your SDI accessory is using batteries that don't have any grounding and you don't follow the procedure outlined by RED, then you may eventually find yourself with a major issue on-set. P-Tap/D-Tap connectors also don't use grounding and should be avoided at all costs. From RED: Make sure power is connected to the SDI accessory at all times before you connect the BNC to the camera. Ungrounded power from SDI accessories can damage the camera’s SDI port. To avoid this possible damage, attach the power source to the accessory before attaching it to the BNC cable. Also from RED: When possible, avoid using P-Tap (also known as D-Tap) cables to power accessories. To avoid damage when using P-Tap/D-Tap, it’s imperative that the connect/disconnect sequence is used.
This whole problem only applies if you power both the accessories and camera off the same battery. If you power the monitor from separate batteries it literally doesn't matter when you plug in the SDI or any other cable or turn on and off stuff because there is no way to complete the circuit through the SDI.
There is one cable anyway.... The SDI cable can bring to the Komodo excess or current peaks from the monitor, irrespective of the battery powering it.... Not saying you’re wrong, but your rationale has gaps, IMO...

I’ve heard that you need to power on both monitor and camera first before attaching SDI and then reverse the order on shut down so SDI last when powering and SDI first on powering down 😮
sorry mate but i believe internet says you have to have the camera ON aswell BEFOR Pluging the SDI. Basicaly its ---> All on befor SDI / SDI out Befor ALL OFF . Correct me if im wrong . :) Cheers BTW thanks for your videos !
Make sure EVERYTHING is on, camera, monitor, all AKS, etc., before plugging in any SDI BNC cables. If you’re using a Teradek make sure the Teradek is powered as well before implementing any SDI cables. When powering down, I usually unplug the BNC first, then power down monitor/Cam/AKS etc. I may be wrong on the power down, but I’m pretty sure that’s how everyone I know does it. Cheers.
Thanks heaps mate! I have tried both ways and it does seem to be fine. Thanks for that. Although from my understanding the power status of the Komodo doesn't have any affect on this. Could also be wrong though haha!
@@danielkelaart The actual real problem is the grounding . Eitherway when a Dtap is pluged wrong way or when hotswapped battery . One pin touches befor the otherone . that is what grills the SDI. But still unplugging everytime is safer :) Cheers mate !
Remember when disconnecting only disconnect the connection going into the camera. In my case I use a freakshow so I'll disconnect from the freakshow, replace the batteries and reconnect back to the freakshow.
I use a regular 4K SDI and I'm totally fine. I heard it's even safer than using the 12G one. I only use canon batteries though and the monitor has its own battery too obviously. I'm not certain so correct me if this is a mistake.
Somebody can tell me whats happend when you have plug in your sdi cable into the komodo and the batery its empty and power off? Its dangerous to the port??
If you have empty batteries nothing it's going to happen. Now, you have this possible scenario: 1. You're recording and the battery (Komodo or monitor) dies. According to a few UA-camrs this could be something to worry about (I really don't know). According to RED inside their page you can check the article called: "Preventing Damage to SDI Outputs". Which may be a bit confusing since they only refer the issue if the MONITOR loses power But it's a simple process called LIFO: Last In - First Out. You place the battery on the Komodo and your monitor (whatever order) and only then you can connect the SDI cable (no need to turn on the camera, is up to you. Regarding the monitor although it's not needed to do it, they advice to turn it on since there're a few monitor where you don't have a power status and you may plug there an empty battery). Then let's say you need to take a break... According to ARRI after you followed the LI (LAST IN) protocol, you don't need to worry about POWER IN or OFF your devices (Komodo, monitor or whatever accessory). NOW the problem that can happen here is that if the battery dies (discharged or something) you're not following the protocol. Since that's interpretated as the camera was disconnected from the power supply or viceversa. So, most people when they turn off the camera for a while they decide to power everything off (or at least the camera) and they unplug either the camera sdi port or the monitor (no need to disconnect both unless you finish your shooting day). This is basically what I got by watching multiple videos and reading PDFs haha
No ! wrong procedure !!! correct procedure is: SDI (LAST IN- FIRST OUT), if you turn on komodo for last and have power supply plugged in to the wall your SDI in to the camera died ! CAMERA,RECIEVER,MONITOR need to are ON ! and for last one plug SDI !
This is wrong. For Powering on, power both devices first, turn them on, then connect SDI. For shut off, power down both devices and disconnect. Always use a 12G Shielded cable.
The power on and off sequence is about grounding, if your monitor was connected via DTap, you would have blown your SDI as there is a power circuiting through one source and outputting to multiple devices. In this case you have wouldn’t have a grounding issues as there’s no unregulated power out coming from your camera battery.
@@wasislos this is the case with all 12g SDI cameras. I’ve seen people blow the SDI ports on Alexa’s as well as 12g recording decks and devices. It’s not a red Komodo problem, it’s a 12g SDI problem all around.

Do you have proof that this whole process can be ignored by powering your accessories with different batteries?
How can you be sure?
@@MrSlapp Because of the way electricity works... There is only one cable connecting the two devices, no way for current to flow, no loop....

It’s about grounding every device the sdi comes into contact with before connecting, essentially.
I’ve heard that you need to power on both monitor and camera first before attaching SDI and then reverse the order on shut down so SDI last when powering and SDI first on powering down 😮
I really was looking forward to getting a Komodo. But this is deal breaker that you have to constantly unplug the sdi. Are all red cameras like this?

Turning on - SDI last in Turning off SDI first out. (LAST IN- FIRST OUT)
If the batteries die and the monitor turns off, how can I disconnect the sdi cable?
That happened to me, disconnect SDI first. Even if the battery is dead, it's still completing the circuit. Then replace the batteries.
@@Dubi00 thank you
