To receive the image sent from my SkyZone TS5823 FPV transmitter, I bought a FPV LCD monitor with two built-in receivers, supporting diversity.
It’s named RX-LCD5802, and I’m pretty sure it’s from Boscam. You can get it from eBay, Amazon, Banggood, HobbyKing etc, and it’s usually less than $140!
The main features that brought me to this specific monitor are:
– Two built in receivers, supporting diversity
– Built-in 2450mAh (claimed) LiPo battery
– AV in/out
– Integrated sun screen
This makes it really easy to use a monitor instead of goggles. It’s cheap, and you can mount it on a tripod or even directly on your transmitter. As I’m still a beginner, I like to be able to switch quickly between watching the model and watching first person, this is easier on a monitor than goggles.
I was happy to see that the manual’s translation error “MEUN” instead of “MENU” was not printed on the monitor.
The model was well protected in the box, so fortunately it came in one piece. It was heavier than I thought, so it’s going to be very noticeable attached to the transmitter, but with a neck strap, it’ll probably be fine. A video in and out cable was included, in addition to two linear antennas. There was no charger included, only a barrel plug to JST adapter cable, which really doesn’t make much sense. You’re NOT supposed to use a charger on this monitor, it has its own built-in charge circuit, and only needs a 12V power supply with 1.5A or more. This will make sure you’re able to use it while charging. I found a $10 power supply on Amazon, and if my measurements are correct, the monitor needs a 3.5mm x 1.35mm barrel plug power supply, which can be plugged straight in the monitor to charge it.
In addition to the box, HobbyKing had included a larger sun shade which can mounted over the existing one.
After powering up the monitor, I was really happy about the choice I made. The brightness and contrast is amazing! Even at 50% brightness (default) it lights up its surroundings, it will hopefully give a crisp image out in the sun. The sharpness will probably have to be adjusted a bit to give an optimal picture, and the colors can be a bit unnatural, but I want the colors to be brighter than real life, this makes it easier to distinguish between objects on the monitor.
At the front left of the monitor, you have three LED indicators, RF A, RF B and battery. Battery has a red LED while charging, and blue when finished. RF A/B will light up to show you which receiver is being used, although they can be a bit confusing.
The “Source” button will switch between four different modes, and RF A/B will alternate when switching, so you’ll have to look at the top left corner of your screen to see what’s actually chosen.
When you click source, it will light up “A, B, A, B”, but you’re not just alternating between the two receivers, you’re actually choosing “RF A, RF B, AV IN, Diversity”, even though the LED is just going front and back.
The setting you’ll want to use is the last one, Diversity. When chosen, it should automatically switch between the two receivers, always using the one with the best signal. It should alternate between the RF A/B LEDs on the front to tell you which receiver it is using.
Testing with TS5823 and GoPro Hero 3+ Black
I have my GoPro at 1080p50 and medium width (so the legs on my quad aren’t visible). The TS5823’s wire harness is plugged in the GoPro and the 12V output of my quad, and the GoPro is turned on with it’s WiFi remote. I’ve set the TS5823 to band “F” channel “1” (5740 MHz), which is the same band as FatShark, ImmersionRC etc are using. The monitor’s group and channel buttons are then used to set the monitor to group “D” (which is really the “F-band”) and channel 1.
Both are now at 5740 MHz, and I instantly get a picture on the screen. I don’t hear any sound, but when turning up the volume on the monitor, I get feedback, so it seems to be working as it should.
I’ve never used the video out on my GoPro before, so I didn’t know that it has an OSD on the output. This makes it easy to see how much battery life the GoPro has, in addition to see if you’re recording, video mode etc. The only problem is that the monitor’s OSD, which I haven’t found a way to disable or move, is also at the same place, so the battery-icons are overlapping, making it hard to see the monitor’s battery indicator properly. But nothing to worry about, the monitor has over an hour of battery life, and the GoPro has approximately two hours, much more than my quad can fly on a battery. Btw, as it’s a LiPo battery in the monitor, it shouldn’t be stored at more than 50% charge, that would probably hurt the battery over time.
To get less interference, the antennas could be replaced with one circular polarized antenna in addition to the linear one, or another replacement. This would utilize the diversity feature of the receivers. SMA male antennas are needed to fit the monitor.
