Interface card layout
Throttle levers potentiometers are moved from Axis Card
to DC Motor Card. This means space for Rudder and Tiller on the Axis Card
and I can now use the Rudder/Tiller coordinate function in FSUIPC.
In- Out module
Cards are mounted on a 180x125mm sheet of alu. Spec
fittings cause the modules easy can be placed or re-placed in two rows on
the left side of the centre forward e-bay. An exception is the USB Axis, USB
Servo and Relay card witch are placed directly on the TQ.
Relay Card TQ
TQ with Relay Card. I use Relay for Parking Brake light, Spoiler
motor auto deploy/stow and
Trim motor up/down (2 relays)
To day (2017) I also use relays for Gear Lever Release
and Parking Brake Release (solenoid)
Back of the MIP. Master card #2 and above the In-
and Out- connections Cards. Down-right you can see my home made light
OH - Panel
Back of the OH-panel. Interface cards from Opencockpits. USB expansion
Card #2, two Master Cards, one Display Out card, two Display II cards and two
USB Servo cards.
DC Motor Plus Card
Throttle Unit with USB DC Motor Plus Card from OC (upper). Bellow my old
Axis (Joystick) card and a servo card.
The manual to the card is good but it tells not every thing and for long
time I had great problems with USB disconnection. OC support told me to
connect pin 1 and 2 on unused analog input and to remove the noise damping
capacitors between motor connector and motor housing. This solved many of
the disconnect problems but still with 4 motors connected it was not fully
stable. (Analog input AN1 to AN4 work only up to value 127 above they get
The card is only rated for nom. 2A and it is for the total numbers of motors so
maybe my motors are to powerful. With 2 motors it works fine and my Trim-
and Spoiler Motor are instead of controlled by relays as before.
All the Throttle potentiometers are configured and calibrated in Prosim Levers config.
You need also a
little SIOC script with only 3 inputs from Prosim:
AT power ON gate
Lever 1 servo output numerical
Lever 2 servo output numerical
Remenber the SIOC subroutine for
reading the servo output more times/ sec. otherwise the levers donīt move.
Until now I have only few flights with the updated Throttle but it seems to
work well. I hope one day to upload a little video showing how nice
and steady the Levers are moving.
