Elo Interactive Digital Signage products support technology that greatly simplifies remote management and diagnostics. With appropriate software implementation, it will reduce on-premise support calls and help
maintain a consistent user experience.

This application note discusses all local interfaces to the IDS display. Two methods are possible: over the video signal using the VESA DDC/CI protocol and over USB using the MDC protocol.

The VESA protocol enables the full functionality found in the Elo Display Device Client while the MDC protocol provides backward compatibility to the 00 series remote management features.

Elo’s Interactive Digital Signage (IDS) products are available in 32" to 65" and include the thinnest (3-3.5") all-in-one commercial touch displays on the market.

• Note: .NET framework is 4.0 or above is required for Microsoft framework. 

I. MDC Protocol

All Elo Touchscreen Signage support the Eloview MDC protocol. This provides device control/status via the monitor USB interface. For Elo customers who have utilized the IDS 00 series MDC remote management capabilities, this enables seamless backward compatibility with all Elo Touchscreen Signage monitors. Access to the MDC protocol via a virtual com port is provided by the Elo driver. Remote management functions and command set protocols are the same as with the 00 series.

Connections and Setup

Elo Touchscreen Signage has a USB connector which allows access to touch, MDC functionality and other peripheral devices (e.g., web cam and RFID reader) connected to the unit. This is implemented through an internal USB hub. MDC functions are implemented on a virtual serial port. If you are using an Elo Computer Module you can skip steps 1 through 3.

Step 1: The Elo VCP driver is required to be loaded. This can be downloaded from http://www.elotouch.com/Support/Downloads/dnld.asp (part of driver pack for IDS Computer Modules install CP210x driver for IDS01/02 and PL2303 driver for IDSx3.).

Step 2: Connect the monitor touch USB cable to the host computer.

Step 3: In the On-Screen Display of the IDS monitor, navigate to “MDC Protocol” and select “RS232C” (Only need for IDS01/02).

Step 4: Select the virtual serial port on the Host computer. Procedure for Windows: In Control Panel, open Device Manager. Under the Ports (COM and LPT) group, you will see a “Silicon Labs CP210x USB to UART Bridge (COMXX) or "Prolific USB-to-Serial Comm Port (COMXX)” listed. With XX being the available Serial (COM) port number which the ELO VCP driver has been mapped. The application (e.g., content player) that is managing the device should send hardware control commands to this port. The virtual serial port setting is 9600/8-N-1(baud rate 9600, eight data bits, no parity bit, one stop bit).
