+=====Firmware Copyright=====
+Copyright(c) MERG and Rocrail.\\
+Commercial use is prohibited.\\
+ \\
+Latest developments have proved that use of RC522 with 13,56 MHZ NFC is much cheaper to use.\\
+Also, there very thin and cheap Tags available for this.\\
+The used RC522 sensor boards a passive type so the need of an extra simple interface is required.\\
+See for a more detailed descrioption at **[[gca41-en|GCA41]]**.\\
+ \\
+===== Features =====
+  * 8 channel RFID reader input using the same type as **[[rfid12-en|MERG ID12/ID20]]**.
+**OR**
+  * 8 channel RFID reader with **[[gca41-en|GCA41 and RC522 13,56 Mhz RFID unit]]**.
+  * Connector for various 8 channnel current and Hall-sensor detectors. (GCA93 / GCA94 / GCA173).
+ \\
+===== Tips for IDxx sensors=====
+  * The displacement between RFID readers, **ID-12LA**, should be at least 30cm to be able to function.
+  * The distance between reader and transponder is for small types critical; Create a test environment to test it to find out the best placement.
+  * See for more information: **[[:sensor-bi-directional-en|Bi-Directional Communication]]**.
+\\
+===== Tips for GCA41 with RC522 RFID sensors =====
+  * See **[[gca41-en|GCA41]]** for more details.
+  * In addition to installing the RC522 sensor right under the track, there is a small pcboard coil available from GCA.
+  * See **[[gca:gca-index-en#antenna_for_rc522_n-scale|N-scale coil]]**.

+===== Description =====
+Merg did a fine job in combining 8 RFID sensors attached to one board and from there read all sensors and send a completed number over the serial port to a PC.\\
+This board is stepping a bit further by doing the same thing and in addition has CBUS on board so the separate RS232 port is no longer needed.\\
+The received numbers are simply send via the CBUS.\\
+Allthought Rocrail can handle also the MERG RFID concentrator, connected to a serial or USB port, this CAN-GC4 is a bit more easy to connect.\\
+To power all connectable 8 RFID sensors, the board needs a power supply of approx 0.25Amp at 5V.\\
+For a linear regulator 5Volt , this is way too much for continuous functioning.\\
+The CAN-GC4 steps down the 12 Volt as available in the CBUS network by means of switching power supply.\\
+It saves energy and also avoid hot parts on the board.\\

+====LEDs====
+^ LED# ^ Function ^ Aspect ^ Remark ^
+|  1 | CBUS activity | random flashing | Depends on CAN traffic |

+|  3 | Learning mode | 500ms blinking | Activated by push button or Rocrail setup. |
+|  3 | RFID checksum error or the ID is not in the list of allowed RFIDs. | One shot flash |   |

+===== Setup =====
+| {{:cbus:cangc4-cbus-setup.png}} |
+====RFID sensors====
+CAN-GC4 RFID concentrator can connect up to 8 GCA41 with a RC522 each.\\
+Since the interest in ID12 sensors is down to zero, descriptioon about this sensor is discontinued.\\
+====BK Column====
+The 8 block occupation detectors, GCA93, GCA94 or GCA173, can be assigned an address used for CBUS events.¹\\
+====Allowed RFID Column====
+Used in combination with the Check RFIDs option for generating only events for IDs set in this list.\\
+Starting with revision 3458 the RFIDs must be set in [[http://en.wikipedia.org/wiki/Dot-decimal_notation|dot-decimal notation]].\\
+"5555" would be "0.0.0.21.179". The easiest way is to copy the dotted RFIDs from the Rocrail server trace.\\
+====Options====
+See **[[cangc4-firmware-en#node_configuration_byte|Configuration byte]]**. \\
+===Save RFIDs===
+Used for SoD; Use with care → Old information is reported!\\
+===Check RFIDs===
+The incoming RFID must be in the list of allowed RFIDs for generating a CBUS event.\\
+===Release RFIDs===
+An event with OPC_ASOF is send after 2 seconds to release the related sensor.\\
+===Accessory events instead of RFID events!!!===
+| :!: __No RFID event is generated if this option is active!__ |\\
+For use in combination with check RFIDs to trigger an output on the CAN-GC2.\\
+ \\
+¹) //In Rocrail this is the sensor address.//\\
+ \\
+=====RFID Notation=====
+The RFID(Identifier) is formatted as [[http://en.wikipedia.org/wiki/Dot-decimal_notation|dot-decimal notation]] with 5 parts: \\
+^ Dot-Decimal ^ Hexadecimal ^ Decimal ^
+| 255.255.255.255.255 | 0xFFFFFFFFFF | 1099511627775 | \\
