+======Introduction ======
+This unit is identical to the GCA123, but now for use with CBUS.\\
+The popularity of using your Android or iPhone for controlling turnouts is growing.\\
+But still I hear people who are opposed to it, because it is mostly not a single handed easy to use device.\\
+For example the CAN-GC5 or RocoMaus are confortable for controlling a train, but commanding switches need always the\\
+information about he address of the turnout to be commanded.\\
+This unit can sometimes be of a better help.\\
+Specially for testing turnouts, or manually fiddling around with trains over a few turnouts, this unit CAN be extremely useful.\\
+The outside look is virtually the same as the GCA123, fitting in the same box.\\
+Programming is done in the same way as for CAN-GC2(a).\\
+Also a nice front panel is available now, which also fits the GCA123.\\
+Standard, the front plate indicates 8 Switches, left for straigh position, and right for turn.\\
+But with specal configuration in the turnout, it is possible to control 16 turnouts.\\
+\\
+===== Assembling instructions =====
+A few remarks have to be made to help you being succesfull with the production of this unit.\\
+Picture shows different pcboard but the idea is exactly the same.\\
+Fix the empty PCB with screws in it's future housing, and use it to drill the exact positions of the pushbuttons and leds.\\
+{{:mgv:hardware:mgv124-pict-01.jpg|}} Use the pcb as a mould for holes of pushbuttons and leds.\\
+Pushbutton and led positions have a little center hole for this purpose.\\
+All other parts can be mounted after that.\\
+The pushbuttons and leds are mounted at the backside of the PCB.\\
+Please take care not to use the center hole of the leds for soldering, because that one is only a drilling mould.\\
+After a serious check, connect the pcb , without IC's inserted, to CBUS. Check if 5 volt is correct between pt 8 and 20 in IC1 socket.\\
+CAN-GC12 will announce itself in programming the CANBUS as a CAN_GC2, because it is internally the same thing.\\

+====== Confuguration for commanding turnouts / signals ======
+A turnout can have the same adress in CBUS as the pushbutton to command it.\\
+If you program the address (or adresses when it is coil driven motor) the same as the turnout.\\
+It will work fine that way, but these buttons are now not noticed by Rocview, so the visible position on screen will not change.\\
+That is Ok, if you are not running Rocview, but it is very inconvenient when Rocview is there and shows wrong positions.\
+To overcome that issue, start using virtual address(es).\\
+The simplest way is use adresses that are far out of the range you are using.\\
+For example you use addresses 1-100 for your turnouts, use 1101-1100 as virtual addresses. \\
+You are rather free to choose any number, up until 9999. ( maybe even further, I never tried).\\
+Now you have to enter these addresses (here in example address 1123) in CTC area of the wiring popup page like shown below.\\
+This example shows the seup for a servodrive with CAN-GC6.\\
+For commanding coil drive use two adresses, unmark command 'FLIP' and mark resp. 'STRAIGHT" or 'THROWN'.\\
