How to put V8R4-II into binding mode respectively


V8_Mode (Non-telemetry)
Connect battery to V8R4-II while holding the F/S button on V8R4-II

DFT, DJT, DHT, DHT-U in V8_Mode (Non-telemetry)
(Switch 1 OFF and Switch 2 ON)

DFT, DJT, DHT, DHT-U in D_Mode (Telemetry)
(Switch 1 OFF and Switch 2 OFF)

D_Mode (Telemetry)
Connect Ch1 & Ch2 signal pins of V8R4-II by provided jumper and then connect battery to V8R4-II directly (no need to

hold the F/S button on V8R4-II)(Note: Does not send any telemetry data.)

For thermal gliding, typical values of the 4 param could be -3 -0.3 0 3. For other type of fligth, adapt freely according your preferences.

Right, good question, you need to tune those values to match your planes sink ratios, the 2 inner numbers are dead zone

which will stop any beeps, the 2 outer numbers control how fast the beeps go for a given rate of ascent descent.
I tune the numbers so that for a normal flat glide the vario is quiet but hit a bit of sink/lift the beeps start. The

outer numbers are up to personal pref really but the lower the numbers the more sensitive it will be.
My minimoa need a 0.1 in the lift and -0.7 in the sink to get it about right, my blaster dlg need 0.2 lift and -0.3 in the sink.

Outer settings can be left as is with no real impact, inner settings you tweak say the sink value "in the air" till it just stops beeping at...Continue Reading
