   *  GCA77  8 x 0,5 A output switch
   *  GCA107 8 x relay board.
+Because this unit is directly connected to DCC, it is not possible to use it for input.\\
+GCA does not support S88 connections in any way.\\
+Configuration and adjustment of servo's is done by use of special program, via USB port.\\
+See descirption below.\\
+The G-ASH-03 has an isolated input for DCC, and needs a separate power source like a 12V 1Amp adapter.\\
+Two jumpers on board make it possible to use the DCC power from the rails for supply.\\
+It is not my favorite, because:\\
+a) you will need much more 'expensive' booster power with larger layouts.\\
+b) any shut off in the DCC booster/command station will also cause the function decoder to stop\\
