+The CAN-GC2 is a sister of the GCA50 with the same capabilities, but running on the CANBUS open source CAN standard. \\
+the CAN-GC2 can be mixed with GCA50 units on the same cable, but of course need different computer interfaces.\\
+The also available CAN-GC3 will bring a complete solution for DCC Model Railroading in DIY. \\
+The CAN-GC1e connects the computer with the CAN bus. All the well known MGV*/GCA* satellite boards are useable with the CAN-GC2.  \\
+ \\
+===== The pcboard =====
+|   {{:cbus:can-gc2-pict03.jpg?600}}   |
+A jumper makes it possible to set terminator on the last board in the RCAN chain.\\
+This jumper connects a 120 Ohm resistor to the RCAN system.\\
+White connectors at the back are compatible with all [[:mgv-overview-en|GCA(MGV)xx interfaces]].\\
+These interfaces are all electrical isolated from CANBUS by optocouplers.\\
+Power, as available in RCAN-cable, is -where ever important- generally only used for supply of RCAN board itself, \\
+with a few minor exceptions.\\
+As a standard recommandation for all CAN systems, connection and disconnection of cables is not possible while system is running.\\
+Using this cheap and rigid d-type connector with locking screws will avoid that connectors drop off accidently.\\

+[[http://wiki.rocrail.net/doku.php?id=mgv-overview-en#direct_connection_of_led_s|Led connection]]
+\\
+===== Reed switches and hall sensors =====
+Read switches and hall sensors can be used as feed-back sensors.\\
+However, since the contact information inside the CAN-GC2 is arranged so that the unit is\\
+low sensitive for distorsions, the minimum Pulse lenght to be accepted by CAN-GC2 is 50 miliSeconds (0.05 second).\\
+In addition to that, reed-contacts usually give more than 1 pulse when activated, known as 'contact dender'.\\
+For this way of sensoring, a special pulse-extender is available. See __**[[gca173-en|Hall sensor and reed switch unit]]**__\\
+===== Hardware for CAN-GC2 =====
+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 PICKIT3 from Microchip.\\
+The on-board ICSP connector is useable for this programmer.\\

+===== Setup =====
+{{:cbus:cbus-gc2.png}}\\
+====Reset EEPROM====
+Hold down the button at power on to reset/initialize the EEPROM with following settings:
+  * port 1-8 switch with address 1-8
+  * port 9-16 block with address 9-16
+The same can be achieved by sending a **[[:cbus:flim-en#clear_all|Clear]]** command.\\
+====Set====
+Set the first found change. This button must be pushed multiple if more then one port or setting is changed.\\
+The sequence of change check is:
+  - Ports
+  - Node configuration
+  - SoD
+====Set all====
+Set all ports and options.\\
+====Save output state====
+Write the output state in EEPROM after detecting a **power off command** on the CANBUS.\\
+The outputs will be restored after the [[:can-gca2-en|CAN-GC2]] is powered on.\\
+====Short events====
+Ignore the event node number and compare the event number only.\\
+====Long events====
+For long events the BUS variable on the interface tab of sensors, switches and other objects is used to address the module its node number.\\
+The address variable is equal to the one used with short events.\\
+====SoD====
+**"Start of Day"**\\
+The [[:can-gca2-en|CAN-GC2]] will report the status of every input after receiving an accessory command with this address. (Short event)\\
+The SoD address should be the same as set for the __**[[:cbus-en#sod|Controller]]**__ and can be tested with the **SoD** button.\\
+===All===
+If 'All' is not set, only high inputs will be reported at SoD.\\
+====Node Nr.====
+For outputs with long events only.\\
+Inputs will use the **[[:cbus:flim-en#node_number|CAN-GC2]]** node number for events.
+====Port types====
+^ Type ^^ Description ^ Recommendation ^
+| **IN** | Input | Normal input port. | Push buttons, feedback of servos/points and hall sensors. |
+| **BK** | Block | Input with a 2 seconds delayed off. (±50ms) | Occupancy detectors. |
+| **SW** | Switch | Continuous output. | Single coil switch drivers like servos. |
+| **PU** | Pulse | Output with x ms activation time. (±50ms) | Note: A [[:switch-int-en#switch_time|software timed off]] is not possible with CANBUS; It is realized in the hardware. | \\
+====Pulse time====
+Activation time for pulse type outputs.\\
+====Inv====
+Inverts the port.\\
+ \\
+====Test====
+Every port has a test button in which also the current state is displayed as a "1" or "0".\\
+The state is only updated after pushing a test button.\\
+ \\
+====Usage====
+Shows the Rocrail object ID which is linked to this port.\\
+ \\
+====LEDs====
+The information of the LEDs is explained on the firmware page: **[[:cbus:can-gca2-firmware#leds|LEDs]]**\\

+=====Node Variables=====
+^ NV# ^ Purpose ^
+|  1  | General configuration |
