CVG Quick Start

CVG Quick Start Guide:

Want to learn how to setup and use your CVG module without all the hassle of a long manual, forums, or long YouTube videos? This is the page for you!

Installation:

Once you receive your ClearView Module, install it in your goggles (leave the cover loose for now). Please follow the compatibility chart carefully. Iftron is not responsible for user error, which may damage Fatsharks. A video of the CVG-Original install with ribbon can be seen here. The CVG-HDO does not come with a ribbon.

NEVER RUN A CVG LEGACY ON HDO GOGGLES! 

At this point, we still do not recommend the inductor mod (see table footnote), but if you already modded your goggles, the HDO version will work.

*Recommended to run legacy goggles on 2s to limit heat generation in the head-tracker regulator.

**Recommended to run modded legacy goggles on 3s. If Fatshark battery is below ~8V, the voltages sag too much in modded legacy Fatsharks, such as the Dominator and HD goggles. The inductor mod does not guarantee a stable 5V supply at lower input voltages, thus a 3s battery should used

 

Next, power on the goggles. Ensure the ClearView LED lights up on the board, and you see static on the screen. Attach some antennas. If you don’t see static, change the position of the module switch on your goggles. If you tried both positions, and you don’t see static on your FatSharks, STOP! Unplug your battery. Double check the compatibility chart again, and then ask us for help.

Using the menu:

The CVG module has 12 usable bands, and utilizes Fatshark’s channel buttons to change channel. The CVG module also uses a unique navigation button behind the SMA antenna. Press on the SMA when the CVG is plugged into the Fatsharks to actuate the button.

For an overview of the menu, click here. If you’ve used a ClearView Racer or Pro menu, you can skip the video, as the menu system is similar.

Turn on your video transmitter. If you do know the band, then enter the menu, select the appropriate standard band, and use the Fatshark channel buttons to find it. If you don’t know the band, either figure it out from your video transmitter manual, or use the band analyzer. The band analyzer in spectrum mode is a good place to start finding your frequency.

Flying with ClearView:

Once you have video from the aircraft, wait for a ClearView lock (typically 5 seconds to 30 seconds). The OSD will appear when this is the case. If you can’t aquire a lock in AUTO camera mode, try NTSC  or PAL mode, and go back to live video to wait for lock.  Flying without a lock will result in similar performance to standard diversity receivers. ClearView lock improves image quality, removes analog multipath artifacts, rejects adjacent channel noise, and most importantly, stabilizes the picture to avoid a rolling and tearing image.

The ClearView OSD provides vital information from the such as the current band-channel, receiver frequency, antenna in use, antenna RSSI, as well as some user text. The RSSI meter is a great place to judge how strong your signal is, however ClearView has at least 6dB more of range past when the RSSI is at zero bars, so feel free to push it to lower signal than you’re normally used to flying. Tiny Whoop’s are great platforms for getting comfortable with ClearView’s signal degradation characteristics.

Antenna Selection:

ClearView works best with two antennas. In the past, it was recommended to run similar antennas. While this gives the best noise performance, there are situations where an asymmetrical setup is beneficial. If this is your first time flying the CVG, we suggest that you start with two omni antennas oriented the same way (vertically). If you want to fly both far out and behind yourself, use a directional antenna + an omni (either side). This will still give you excellent noise performance as long as both antennas are receiving sufficient signal. When your range exceeds one of your antennas, or when flying behind your directional at too far a distance, noise performance will be lessened. Finally, if you plan to fly very far away, use two directional antennas facing the same direction. With 2 directionals, remember not to fly too far behind the antennas, and keep your head pointed in the right direction when using directional antennas. Two directional antennas pointed the same way will offer the most range at the expense of coverage behind the antennas.

Updates:

From time to time, updates will be released for the CVG. Although the performance from the first release of 1.05 is already fantastic, bugs will be fixed, and new features will be released. Updates require a future proofing cable (Type II), or similar FTDI adapter. To update your receiver, click here for a guide.
