Elo 2218 vs 2216 Comparison Chart

Supply Voltage and Current

• +5 VDC, nominal (+4.50 VDC to +5.25 VDC). Self powered only.
• 25 mA standby minimum, typical at +5 VDC; during touch 110 mA typical
• Average power dissipation is 0.56 W, typical

Interface-Serial

• EIA 232E (Serial RS-232), DCE configuration. 8 Data Bits, 1 Stop Bit, No Parity, Full Duplex
• Hardware handshaking: RTS/CTS
• DSR is pulled HIGH (>+3V) by the 2218 when connected and powered.  DTR can be asserted by the host to interrupt the flow of data from the controller. 
• Note that if the application does not monitor CTS, then an interval of approximately 5 seconds should be inserted between the issuance of a reset command and any other command.

Communication Parameters

• Baud Rate 9600 (default), and 19200
• 8 Data bits, 1 stop bit, no parity only

Interface-USB

• The 2218 is a full-speed USB device. If the USB is connected to the controller, the controller will communicate over the USB, and will not communicate over the serial port.
• The 2218 is never powered from the USB – it is self-powered only.
