 +
 +To complete the D-connector type set of CANBUS Pcboards, this is the DCC Command Station.\\
 +It features all that is on the original CAN CMD, but with a few firmware and hardware adaptions to easy interconnect with CAN-GC1 and CAN-GC2.\\
 +The CANBUS CAB1 is 100% compatible to be used with this programmer.\\
 +The slightly larger CAN-GC5, without SMD parts is available now.\\
 +
 + \\
 +
 +
 +===== Important changes =====
 +
 +\\
 +^**CBUS Loco direction flag has been changed!**^
 +\\
 +starting with revision 8778 the loco direction flag is corrected to match the DCC-NMRA standard.\\
 +Please swap the loco placing before running in automatic mode after you updated Rocrail to 8778 or higher.\\
 +^
 +\\
 +
 +===== Features =====
 +{{  :cbus:can-gc5.2_pict06.jpg?150}}
 +  * Separate supply not needed. That is already available from CAN-GC1.
 +  * It is possible to use CAN-GC3 as stand alone with a 15V dc supply, together with CAN-GC5V2.
 +  * All connections and Leds in front, for easy build in your own housing.
 +  * Booster output. RJ12 connector for connection of **[[:ord3-cs-en|ORD-3]]** booster(s).
 +  * RJ22 connector J3 for direct coupling of MERG CAN-CAB or CAN-GC5V2.
 +  * 1A Internal booster, also useable for connection to programming track (J5)
 +  * Front switch to select programming track or main drive.
 +  * Refresh stack of **32** slots.
 +  * Optional power button.
 +  * **Mobile DCC support __only__.** Use the **[[:can-gca2-en|CAN-GC2]]** for accessories.

 +===== Connection cable for CAN-GCA system =====
 +Cable connections are explained on **[[:cbus:overview-en#connection_cable|this page]]**.
 +
 +===== Connectors & LEDs =====
 +^         functions   ^
 +| 1 | Connection to programming rail, max 1Amp output |  |
 +| 2 | Main/Programming track indicator | On=Main track, Off=Programming track |
 +| 3 | Main/Programming switch |  Up is normal mode, down is programming mode  |
 +| 4 | Booster output power indicator |  |
 +| 5 | Connection for ORD-3 booster(s) |  |
 +| 6 | CAN bus with 12 Volt power (output) |   
 +| 7 | Connector for CANCAB |  |
 +| 8 | CAN bus with 12V power (input) |  |
 +| 9 | CAN bus activitly indicator |  |
 +| 10 | Power indicator |  |
 +| 11 | ICSP: Programmer and optional power button. |  |
 +
 + 
 +===== Power button =====
 +An optional power button can be added to the ICSP connector on pin 1 (RB7) and pin 5 (Ground).\\
 +Pin 1 is closest pin to resistors R1 and R8.\\
 +**[[:cangc3-firmware-en|Firmware]]** version 433 or higher is needed.\\
 +This button controls track power and reports this on the CAN BUS to inform Rocrail.\\
 +{{:cbus:pushbutton_connection.png}}
 + \\
 +
 +=====Setup=====
 +The current firmware does not need any configuration.\\
 +All Loco, Programming and Booster commands on the CAN BUS are processed by the CAN-GC3.\\
 +It is not possible to have multiple CAN-GC3's in one and the same CAN network segment.\\
 +
 +====CanID====
 +The CAN-GC3, CANCMD, has a fixed CanID:\\
 +^ 114 ^\\
 +Avoid using this CanID in other CAN-GCA nodes.\\
 + \\
 +=====Programming Track=====
 +The CAN-GC3 supports Page mode and Direct mode programming.\\
 +Normally Direct mode should be used for common decoders.\\
 +Check the __**[[:pt-en#direct_byte|Direct mode]]**__ option before programming.\\
 +
 +===== Programming power =====
 +The standard 12V, coming from CAN-GC1e , is used for programming track as well.\\
 +Allthough other programmers often also work with no more that 12V, \\
 +it seems that some decoders have a bit of a problem with that.\\
 +To solve it, a higher Voltage will be the solution.\\
 +For this reason, the VR1 regulator on CAN-GC1e can be swapped with a LM2576T-adj type.\\
 +Pot1 on CAN-GC1e is already there and in that case can be used for adjusting the output between 12,5V and 18,5V.\\
 +CAN-GC1e will be equipped with the mentioned regulator from this day on.\\
