![]() ![]() Aceptación de pago con sistemas de cobro sin efectivo. ![]() ![]() Protección contra corto circuito en tarjeta. La interfaz cuenta con 2 puertos MDB, esto quiere decir que puede manejar hasta dos monederos, dos billeteros, dos cashless en una misma tarjeta al mismo tiempo. Mediante una sencilla serie de comandos o Dll la cual permite una integración en cuestión de minutos a su aplicación. On Linux / Raspberry Pi other users have successfully implemented the parity trick, too, see this stackexchange post about a MDB + Pi.īut also with RealTerm, Teraterm, Termite, Bray, YAT or any other RS232 application you should be able to read the data, as long as it handles "Space" or "Mark" parity settings correctly.Permite la comunicación de dispositivos de cobro como Coin Changers, Bill Acceptors, Bill recyclers y cashless devices a una computadora o sistema embebido mediante el puerto serial USB o RS232. It's free for basic testing and there is also a related 9-bit example project. On Windows, you can do such tricks with our Docklight software (see Docklight and MDB). Any data byte will be displayed without error.įor sending MDB ADDRESS and DATA bytes using a standard 8-bit RS232 port, you could apply temporary parity changes: Change the parity setting to "Mark" before sending an address byte, then change back to "Space" before sending data bytes. Any MDB address byte from your VDM will be received with a Parity Error (but still be displayed correctly). ![]() Make sure you receive the original character value even in case of a Parity Error indication. Use 9600 baud, 8 data bits, 1 stop bit, but RS232 parity setting "Space". a plain standard USB-to-RS232 device for PC. ( Wikipedia on MDB: "the mode bit differentiates between ADDRESS and DATA bytes.")īut you can read such data even with regular 8-bit RS232 interfaces, e.g. MDB (multi-drop bus) is 9 bit, because after the standard 8 data bits (like in standard RS232 UART communication) there is a 9th bit called "mode". ![]()
