New setup with lx9070, s10 and PowerMouse

[Sarel Venter]

I am building a new panel and have bought a lx9070 with v8 as the main flight computer, connected to a PowerMouse for FLARM and ADS-B signals.

I have a s10 which I will use as backup vario running on its backup battery in the event of a power failure.

I have them all on a test bed (except the PowerMouse which is still installed in the glider).

I tried to connect the s10 to the lx9070 using a lxnav Bluetooth dongle (which works with my Oudie N), but can't find a way to pair them. Is this possible?

lxnav shows a setup where the s10 is connected to the PC port of the lx9070 with cable LX5-PDA, and the PowerMouse connected to the PDA/GPS port of the s10 using a FlarmView cable. Would this setup work and allow the following:

• Would I be able to upload a task to both the s10 and the PowerMouse when I declare it on the lx9070?
• Would the FLARM signal be passed through the s10 to the lx9070 so that I can display it on the main unit? It looks as though the s10 only allows communication from the lx9070.
• Is it possible to reduce the number of GPS antennas and pass the info between the units? I am thinking of keeping the antennas connected to the s10 and lx9070, and pass the GPS data from the s10 to the PowerMouse.

I would appreciate any better alternatives too. Maybe rather connect the PowerMouse to the PC port of the lx9070 (cable LX5PF) and the s10 to the PowerMouse using a FlarmView cable. Will I have the same functionality as above?

I like the S10 as a backup, and have FLARM connected to it through an LX FlarmACL. The ACL is a hub and also turns LED strobes on in proximity to other aircraft. 

There are other hubs available to split the network connections.

To keep the number of GPS antennas down, consider using splitters* and short jumper cables with (optional) DC blocks. In my case, two antennas feed 5 devices, of which 2 have DC blocks.

GPS antennas capable of being powered by multiple receivers are getting hard to find, so using DC blocks on all but one or two devices may be necessary. Some devices (Trig TN72 being one) are noisy if running through a splitter with other receivers and no DC block.

I have a similar (older) setup.

I have a LX8080, an SxHAWK and a Powermouse, connected via the LX5-PDA and RJ12(GPS/FLARM)-RJ45(FLARM) self-made harness, respectively.

lxnav shows a setup where the s10 is connected to the PC port of the lx9070 with cable LX5-PDA, and the PowerMouse connected to the PDA/GPS port of the s10 using a FlarmView cable. Would this setup work and allow the following:

• Would I be able to upload a task to both the s10 and the PowerMouse when I declare it on the lx9070?

• • Yes (in theory).  In my experience, I don't get the task declared on my PowerMouse. I suspect this is because it is connected to a TrafficView on the other RJ45 port - which is known to prevent declarations due to conflicts over which device is declaring. So I personally don't get the task declared to the PowerMouse (it even says a warning about the task not being declared to FLARM on the LX8080) and I have to separately declare it via the TrafficView  - it's on my to-do-list over northern hemisphere winter to create a switch that can temporarily cut the Tx on the TrafficView which should then allow the task to be declared whilst allowing the functionality of the TrafficView to remain post-declaration.

• Would the FLARM signal be passed through the s10 to the lx9070 so that I can display it on the main unit? It looks as though the s10 only allows communication from the lx9070.

• • Yes. The S10 via the PDA is a data-out as well as data-in. I can get FLARM data on the SxHAWK, the LX8080, the V8 and the TrafficView, all from the data on the PowerMouse.

• Is it possible to reduce the number of GPS antennas and pass the info between the units?

• • I did wonder this with my setup, I recall that you cannot do this as the IGC validity is considered compromised if you receive a data-based GPS signal rather than raw GPS signal - I'm not technical on the protocols but to my layman-brain it made sense why it wouldn't be acceptable, even if it were to be technically possible - so I never bothered to try it. I see the poster before me has mentioned that you can split the raw GPS signal though, so that might be an option.

Just to state the obvious, make sure the baud rate is the same for all three components - go as high as you can.

Cheers.
