 Control it from GCA50 or other I/O units with puls control like switches with coil control.\\
 Board needs 5Volt supply to pin1&2 of J2, and pin3 and 4 are control inputs.\\
-Only J1(partly), J2, K1, U2, JP1, and the two diodes are needed.\\
+See partslist for GCA102V3\\
-\\
+Hall sensors should be positioned at each side of both rail separation cuts., with a distance so,\\
+that one of these hall sensors is activated BEFORE first wheels are touching the rail cuts.\\
+H1 and H2 are positioned at both sides of separation cut left,\\
+H3 and H4 are positioned at both sides of the other separation.\\
+Simple tip:
+If you experience ALWAYS a short cut when train is running into the loop, there are 2 simple solutions:\\
+     * 1. swap the rail connections between the loop rails and GCA102.
+     * 2. swap H1 with H3, and swap H2 with H4.\\
+One of these will be your solution.\\
