| + | =====Firmware Copyright===== | ||
| + | Copyright(c) MERG LocoNet(c) and Rocrail.\\ | ||
| + | Commercial use is prohibited.\\ | ||
| + | ===== 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. | ||
| + | |||
