+MERG has been succesfully developing and using the CAN network for modelrailroad.\\
+The basic idea to follow the trend in GCA (MGV) boards and to have this CAN network adaptable for all available interfaces, like GCA93, GCA136, GCA76 and many others.\\
+The standard MERG units are all made ( so far ) for 8 bytes only, and also different tasks like input, current detection, turnout coils, etc, need different units to connect them .\\
+Most mergCBUS units in this line will have 16 bits on board, and each of these bits ( = ports) is programmable for any task you want.\\
+Rocrail supports this way of programming with extending possibilities, making the whole process of configuration exactly the way it should:  user friendly ! \\
+ \\
+===== The pcboard =====
+A professional produced board with through metallisation, soldermask on both sides and clear print is available now.\\
+{{:cbus:can-gc1_pict03.jpg}}\\
+Connectors also have 12Volt to feed all connecting nodes.\\
+The basic idea is to use this type of board for modules setup, which are frequently disconnected and transported.\\
+These modules can be placed together in different order.\\
+MergCBUS is ideal for that!\\
+The users I have to deal with, like a better connector, instead of fastening wires in screw-terminals.\\
+Therefore I use the easy to assemble and rigid D-connectors.\\
+All interfaces, used for turnouts and other current consuming peripherals, as available from\\
+[[mgv-overview-en|LocoNet interfaces]] are fully compatible and isolated from the mergCBUS system by opto-couplers,\\
+MergCBUS connectors only have to supply mergCBUS system itself, so Subd9 connectors are very well suitable.\\
+All CAN-gcx boards have on-board jumper to connect 120 Ohm to the mergCBUS, of which one should be at each end of the Bus.\\
+Please consider, that it is not allowed to connect- or disconnect the mergCBUS , while in function.\\
+This is a general recommandation for CAN.\\

+\\
+==== USB ====
+[[http://www.ftdichip.com/Products/Modules/USBRSxxx.htm|{{ http://www.ftdichip.com/images/DB9-USB-RS232_web.jpg}}]]
+The picture above shows the board with fitted D-Sub-USB connector. (Its a bit more expensive but the best solution.)\\
+A more 'value for money' solution is to mount standard D-Sub connector and use an **[[:usb-rs232-en|USB-RS232]]** conversion cable.\\
+| :!: **Most RS232 legacy ports cannot handle baud rates above 115200.\\
+ A USB converter is highly recommended.** | \\
+ \\
+===== Hardware for CAN-GC1 =====
+Boards, programmed processors and complete kits are available from www.phgiling.net.\\
+With a proper tool, it is possible to do the programming of the chip yourself.\\
+The programmer , used for these chips is called PICKIT 3 from Microchip.\\
+The on-board ICSP connector is useable for this programmer.\\
+ICSP connector on-board is made conform specification of MERG.\\
+For connection to PICKIT3, the cable cannot be 1 to 1.\\
+See [[http://wiki.rocrail.net/doku.php?id=pic-adap-en|PICKADAP4]] how this is done.\\
+ \\
+===== Setup =====
+CAN-GC1 is based on MERG CANRS and therefore is the setup fort both connector 1 types, RS232 and FTDI-USB, the same:
+| Sub-Library | **Serial** | Do __not__ select USB type for the FTDI-USB connector! |
+| BPS | **230400** | |\\

+===== LEDs & Buttons =====
+{{ :cbus:cangc1-pcb-compside.jpg?300}}
+^ LED ^ Usage ^ Remark ^
+| Le1 | Bus activity | It is not timed and thus only visible at high CBUS traffic. |
+| Le2 | CPU runs | |
+| Le3 | Not used; Leave unmounted. | For future firmware versions. |
+| PB1 | Not used; Leave unmounted. | For future firmware versions. |

+ \\
+===== Power supply =====
+On **J1** a power supply of 12-20 V AC OR 16-24VDC can be connected.\\
+For DC supplies: Polarity is irrelevant.\\
+ \\
+===== Connecting CAN-GC1 =====
+{{:cbus:can-gc1_pict03.jpg?300}}\\
+  - USB or RS232 Sub-D 9 connection. \\ In case of USB: **Make sure the plug is completely in the socket**; It needs a little force the first time.
+  - Jumper for 120 Ohm line termination
+  - CAN Bus with 12V power
+  - CAN Bus with 12V power
+  - Power input 16...24V AC/DC
+  - PIC Programmer
+\\
+===== Compatibility with mergCBUS =====
+The reason for  using  D-type connectors has been explained before.\\
+Electrically , there is no difference between mergCBUS (12V) and CAN-GC .\\
+The following conversion tabel explains how both can be interconnected.\\
+Only four wires are needed.\\
+Use the standard wiring as advised in MERG documentation, i.e. twisted  wires for  the CAN.\\
+^   mergCBUS side   ^   SUB-D connector pin#   ^
+|   CAN-H  |  pin 8  |
+|  CAN-L  |  pin 7  |
+|  + 12V  |  pin 5  |
+|  GND  |  pin 1  |
