Control board for bipolar 20 mA steppers (dashboard stepper), particularly for analog pointer instruments.
Especially developed for bipolar 20 mA dashboard steppers you can connect those directly without a special driver to this board. 16 connectors for steppers are available per board. The coils of the stepper have to be connected to pins 1/2 and 3/4 of the box header. Pin 5-7 are available for a possible IR light barrier or a switch, where pin 5 supplies +5 V, pin 6 needs a TTL signal from the light barrier or the switch and pin 7 is ground. Many dashboard steppers do not need a light barrier to be initialized but can be driven towards the end stop. Please refer to the datasheet of your stepper for details.
The board is connected to the computer with a LAN cable and needs a 5 V power supply (terminal).
The steppers can be configured individually with the software Cockpit Connect. Generally it can be chosen between an initialization via light barrier (endless rotation) or via driving to the end stop.
Currently position data is accepted from FSUIPC and SIOC via the IOCP protocol. The values received are processed by a lookup table and then sent to the respective stepper. The lookup table allows an individual configuration of each stepper with irregularly scaled scales. The creation of the lookup table can be done comfortably with mouse and keyboard, simply change the value until the pointer is in the correct place. An annoying conversion of the scale is not needed.
Additionally a time constant can be defined for each stepper with that a sluggish behavior of the instrument can be imitated.
The connection of more than one board per PC is possible.
