I’m using this to control a remote camera head with 2 motors but cannot get it to enter learning mode and recognise input correctly.
12v power supply, bec jumper connected, analogue (right hand) position selected on rc/serial/analogue jumper.
Input for channels 1 and 2 is from analogue joytstick potentiometers. These are powered from the + and gnd pins on the input block.
I have checked with voltmeter that there is +5 volts across the potentiometer and that the central wiper (ie the input) is at 2.5v when at neutral position.
Chanel 3 not needed so input tied to channel 2
Chanel 4 and 5 enable select are tied to +5 via jumper across right most pins
On power up with both so-gnd jumper and mix jumper in place, blue power led is on and both red and green status leds flash rapidly in unison.
On removing mix jumper (as per user guide) red/green status leds go out and stay off. Blue power remains on.
The user guide suggests that rapid flashing means no valid rc signals, but I have selected analogue with the jumper.
Incidentally, if I remove the so-gnd jumper and power up normally - ie not in learning mode, I get 5 red flashes followed by a green, then repeating - confirming that no calibration has been done.
Could this be a board or microprocessor fault? Any help appreciated!!
