| + | ===== Description ===== | ||
| + | A standard turntable like from Fleischmann or Märklin, has a three wire control.\\ | ||
| + | This controls both start/stop and direction.\\ | ||
| + | It is not possible to connect that directly to GCA50 or CAN-GC2, due to the higher voltage of this turntable.\\ | ||
| + | This unit makes it possible.\\ | ||
| + | Of course this way does not make it full Rocrail automatic controllable, but at least it is possible with two buttons in Rocview, to command the tt.\\ | ||
| + | It requires 16V ac/dc from any standard train transformer, and a connection to either GCA50, CAN-GC2 or GCA_PI02.\\ | ||
| + | On board is a selector to select which 2 out of 8 ports are used.\\ | ||
| + | The other 6 ports remain accessable by a second 10 pin PSS connector.\\ | ||
| + | If any of the two inputs recieves +5V, a direction is selected and the motor will start.\\ | ||
| + | After releasing the button the motors keeps turning until the next stop.\\ | ||
| + | In GCA50 settings select C2 for both ports.\\ | ||
| + | For CAN-GC2 , select single output in interface page of the button.\\ | ||
| + | |||
| + | The red, yellow and gray wires (as indicated on board print) are to be removed from handcontroller, and connected to the pcb.\\ | ||
