+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.\\
