The PHL-2700. For communication the PHL2700 is provided with an IrDA and RS-232 serial interface. Through these interfaces the terminal is able to communicate with the cradle, or apart from the cradle to all computer devices that use IrDA or by connecting it directly to the serial port of the computer. Also belt printers can easily be approached by the PHL2700 thanks to the smart location of the IrDA window.
