BxLCD is a proximity reader to touch-free open the swimming pool or work lockers. The heart of the controller is microcontroller which decodes the data from proximity tags Unique (compatible with EM-410x) using the receiving chip RFID. Programming is through MASTER tag or by using the PC application. The software allows to program all types of tags and to allocate the numbers of the lockers. Communication with PC is by USB interface - virtual serial port or RS485. The tag of MASTER type is to program the all tags and to delete earlier-programmed tags kept in non-transitory EEPROM memory. MASTER tag is for service or for person who is responsible for the building maintenance. Programming of the MASTER type tag is by the PC software. SERVICE tag is designed to open all the lockers (electromagnetic lockers). GROUP tag allows to open assigned lockers. The controller allows to program two different MASTER type tags, up to three different SERVICE type tags and seven GROUP tags. USER type tag enables to open one of twenty lockers which was earlier programmed (by using MASTER tag or by software). GROUP tag allows to open earlier allocated lockers by PC software. LED display on the front panel of the case informs about the number of the open locker. LCD display is particularly useful during programming process and its function is to display the work mode of the device. The whole system is in plastic case 198x144x53 or placed in cabinet wall made off HPL. The maximum load of the output shouldn’t be over 1A and the sum of all output currents shouldn’t be over 5A. Setting output is by putting its potential to ground - that is the locker electromagnet should be connected between + power supply and the controller output. The device is produced exclusively for BxSystem with office in Rzeszow. This company sells and introduces electronic customer service systems ESOK.
