Installing A Power Supply Fan Up Or Down

I've been selling and installing both the RF only and RF+IP models of the ZVPRO since 2015. We had one power supply fail in that time frame. That unit was in a less than ideal location being bombarded with construction dust. The customer also had daisy chained power strips which I'm sure didn't help. That's it. We've had no other issues. All these units are still in service.

It's a power supply.

Cable is fine, but there are NO 'Down' Escalators (only 'Up'). Getting Cable is easy, getting to first-floor, very/very difficult!

CAME WITH MOUNTING SCREWS AND WORKS PERFECTLY! MOUNT ALLOWS MOVEMENT UP AND DOWN AS WELL AS LEFT AND RIGHT PERFECT FOR MY STAGE SIDE MOUNTING SITUATION.

The knurled outer aspect of this line of Step-Up and Step-Down rings is an essential feature.

I found out this converter very useful, it support not only Cross/Up/Down converter, but also Analog to Digital converter since they have a video composite input. However, there is no Composite output, which means there is no Digital to Analog converting. I saw the other review that someone think it's also support D to A, but not at all.

I bought the i7 version with 32 gig of RAM. Build quality is excellent. Very lightweight for the performance. Runs cooler than any laptop I have ever owned. My one complaint is the lack of dedicated Page Up/Down Home and End keys. You have to press a function key in combination with one of the four cursor arrow keys to move up or down quickly. My 2020 HP Spectre X360 is almost exactly the same size as the Dragonfly, yet HP managed to fit dedicated Home, End and Page Up/Down keys on the keyboard. For a high end laptop like the Dragonfly, it's inexplicable that they could not fit dedicated versions of these four frequently used keys on the keyboard. Other than this one issue, the laptop is fast and a perfect travel companion. The built in full size HDMI port is a nice touch for connecting an external monitor or projector. The touchpad is responsive and accurate. Battery life is great so far. Despite my one complaint about the keyboard, I would buy it again, but for this price, one expects perfection, not almost perfection.

I love the Sevenstart St-200 Step Up/Step Down Transformer (200W). The design, weight and performance are excellent coupled with a very attractive prize.

Work awesome, PLENTY of light right where you are looking, also adjustable UP& DOWN. Nice adjustable head band, 3 different intensity settings.I own plenty of these, one for each vehicle I own, on at the back door, and a few in the Barn! Only thing I could hope for is the battery life to be a little longer.

Sensei makes very good rings, I bought all of them UP and Down. They are very accurate and well finished so that rarely they get stuck. This one was to mount a 77 mm Marumi in front of a Sigma 50-500mm (first version). Despite the different thread pitch the Sensei was able to screw in for half turn and was reliable.
