Hello,
I want to use Lightbridge 2 with two redundant flight controllers and a redundancy electronic.  
Is it possible to connect two A3/N3 flight controllers to the DBUS Output of the Lightbridge 2 (what modifications do I need to make)?

Can someone tell me the pinout of the DBUS connector?
Pin1: +9-12V (Input voltage to LB2 receiver)
Pin2:?
Pin3:?
Pin4:GND

Are Pin2 & 3 Output Pins?
Which one is used to send the DBUS Signal?


Kind regards,
Bernd

Hi Jörg,
I found such a cable today at Schw....hofer onlineshop, but it costs €399,-.
I think it is a little bit expensive, if it is only a Y-cable. Would be interesting, if additional electronic has been added, or if it is only a Y-cable.

Kind regards from OÖ,
Bernd

+5 Tx Rx Gnd

Но A3 Получать данные из LB2 в Tx и команду передачи в LB2 к Rx , и я думаю , что только один контроллер будет работать с LB2
You can read data from LB2 using Tx and Gnd wires
Serial 256 000 bps

"0x55" "lenght of frame" "DATA" .........

Yes, they have to send back the telemetry data to the lb2. One channel is for rx signal and one for the tx bsck to lb. One is 9v and one gnd

Hello!

LB2 TX: Can I split the LB2 TX line into two cables, one for each Controller?
LB2 RX: Do I Need to switch the TX lines of the Controllers according which of the two Controllers is active?

Kind regards,
Bernd

I'd like to know about this too. Is the Tx wire from the D-Bus cable a normal S-Bus (PPM) signal?
