+ | 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/ | ||
+ | **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**, | ||
+ | * 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: | ||
+ | \\ | ||
+ | |||
+ | ===== 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: | ||

+ | ===== 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 CAN on board so the separate RS232 port is no longer needed.\\ | ||
+ | The received numbers are simply send via the CAN BUS.\\ | ||
+ | |||
+ | Allthought Rocrail can handle also the MERG RFID concentrator, | ||
+ | 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 CAN network by means of switching power supply.\\ | ||
+ | It saves energy and also avoid hot parts on the board.\\ | ||

+ | | {{: | ||
+ | |||
+ | ====RFID sensors==== | ||
+ | CAN-GC4 RFID concentrator can connect up to 8 GCA41 with a RC522 each.\\ | ||
+ | |||
+ | |||
+ | ====BK Column==== | ||
+ | The 8 block occupation detectors, GCA93, GCA94 or GCA173, can be assigned an address used for CAN BUS 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:// | ||
+ | " | ||
+ | |||
+ | ====Options==== | ||
+ | See **[[cangc4-firmware-en# | ||
+ | |||
+ | ===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 CAN BUS 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.\\ | ||
