Block Diagram

 

The Block Diagram shows the main features of EZMaster: an 8 bit CPU Processor managing the data flow from 6 serial ports and several external devices. The data, received from the USB, COM and LPT Ports or from the external keypad, are processed and executed in parallel tasks, driving the requested function, as DVK Processor, Winkey, Radio Interface, PTT/PTTDelayed line, CW interface, FSK interface, Radio A/B switching line and the BandMap Data Processor. EZMaster include unique operation mode features: standard, extended and advanced. In the standard mode, full compatibility with old fashion communication way is available. Incoming Data from the PARALLEL PORT, USB or RS232 ports are managed to take advantage of EZMaster interface capabilities like the 4 DVK message play, CW, PTT, Radio A/B switching, BandMap Data interface and Radio Interface routing. The extended operation mode share the same input ports, but the user can configure the DVK message to play, the delay between both Radio PTT, and the BandMap Profile associated to the BandMap Data input. The Advanced Mode take advantage of the CPU command mode interface (CMI), that allows, through the USB port, to have full control over EZMaster, saving money by not requesting any add-on port board, and allowing the deepest access level to all EZMaster functionalities
