+ ===== Firmware Programming =====
+Kits will be delivered with pre-programmed chips.\\
+Self programming of firmware is easily done with the right equipment,\\
+and is not realy difficult.\\
+There are many ways to achieve that :\\
+  *  Pickit 2, Pickit3 both from Microchip.
+  *  EasyPic from Mikroelektronika.
+  *  MiniPro from https://www.banggood.com/search/minipro.html (this one is Peter's favorit programmer!)
+and many others.\\
+ \\
+===== Introduction =====
+The **CAN-GCLN** is a CBUS-LocoNet(r) Bridge for sharing specific hardware modules not available on the other side of the bridge or just for migrating from LocoNet(r) to CBUS without loss of investments.\\
+ \\
+//LocoNet(r) is a trademark of Digitrax, Inc.//\\
+ \\
+===== The Bottle Neck =====
+The bottle neck is the big difference between the CBUS and the LocoNet transfer rate.\\
+CBUS uses **125**KBit/s and LocoNet **16**KBit/s.\\
+ This implicates that a burst on the CBUS side can't be broadcasted to the LocoNet side.\\
+ The goal is to make a buffer as large as possible to deal with this, but filtering will be the best option to prevent overflows.\\
+ \\
+===== LocoNet CS with CAN-GC3 =====
+Together with **[[:can-gc3-en|CAN-GC3]]** this Bridge can be used as LocoNet Command Station with service track.\\
+All needed commands are translated into CBUS and visa versa.\\
+To keep sessions alive at the CAN-GC3 side it automatically send every 10 seconds idle time a keep alive request for all active slots.\\
+This is needed because the default purge time in LocoNet Command Stations is much longer then the session timeout in the CAN-GC3.\\
+ \\
+===== Features =====
+  * Support for Digitrax **[[:loconet:transponding-en|Transponding]]**.
+  * Support for Uhlenbrock **Lissy**(IR) and **MARCo**(Railcom(r)) Receivers.
+  * Support for **[[:mgv141-en|Wheel counter GCA141]]**.
+  * Fast clock from CBUS to LocoNet
+  * Jumper to enable power on the RJ12 connectors.
+  * Loconet throttle support; Dispatch from Loconet and CBUS.
+    * Rocrail connected on the Loconet side.
+    * [[http://fremodcc.sourceforge.net/throttle/throttle.de.html|Fremo FRED]]
+    * [[http://fremodcc.sourceforge.net/throttle/throttle.de.html|Fremo FREDi]]
+    * [[http://www.digitrax.com/products/throttles/ut4/|Digitrax UT4 and compatibles.]]
+    * [[http://wiki.rocrail.net/doku.php?id=mgv_fredi-en|GCA124]]
+  * Loco 8 functions and lights.
+  * Start of Day LocoNet -> CBUS.
+  * Service track: R/W CVs.
+  * Programming on the main: PoM.
+  * Slot ping after 10 sec idle.
+  * Extra feature  : Just assembled with connectors, this board is very well suitable as a LocoNet hub.
+ \\
+===== Dispatching a Loco =====
+Before the dispatch command the loco must have a valid CBUS session which can be forced by a zero speed command in Rocview.\\
+Without a CBUS session it is not possible to dispatch a loco for a FRED(i) or other LocoNet throttle.\\
+ \\
+===== Filtering =====
+Filtering is needed from CBUS to LocoNet because CBUS makes no distinction between input and output accessory events.

+===== Setup =====
+{{:cbus:cangcln-setup-en.png}}
+==== LocoNet ====
+=== Read only ===
+Only LocoNet packets are translated to CBUS, not visa versa.\\
+=== CBUS sensor events ===
+Enable the CBUS sensor filter.\\
+=== Start of day ===
+Translate "CBUS Start of Day" to LocoNet to get the actual LocoNet sensor status.\\
+ \\
+==== CBUS ====
+=== CANID ===
+The ID on the CAN bus.\\
+=== SoD ===
+Start of Day event number.\\
+=== Switch filter ===
+Filter definition for the event number range to be translated from CBUS to LocoNet as switch requests.\\
+=== Sensor filter ===
+Filter definition for the event number range to be translated from CBUS to LocoNet as sensor reports.\\
