Connecting Data Transmission Cables

Use a serial cable to plug into the display’s serial port. The serial port uses a male DB9 connector and terminal

block. It can be configured by a UART command or OSD control. Only one of the three interfaces

(RS-232/422/485) can be used at the same time. The pin assignments are shown in the following

diagrams:

Configuring the RS-232/422/485 Serial Ports

For configuring the RS-232/422/485 serial port, please see Appendix B: On-Screen Display (OSD)

Controls and Appendix C: Display UART Commands.

Enabling the Touch Screen Interface (Z models

only)

The MD-224Z model comes with a USB port on its bottom panel. This USB port is used to connect the touch

screen interface to a computer’s peripheral device manager. To enable the panel’s touch-screen feature, use a

Type A male to Type B male USB cable to link the port to a peripheral device input on a PC, laptop, or embedded

computer.

Microsoft® Windows® 7 and above come by default with factory installed Windows HID drivers that fully

support multi-touch, and consequently, for these operating systems you do not need to install a driver that

supports the multi-touch function. Microsoft® Windows® XP and older do not support touch technology, so you

must install a driver to enable the touch function.

Drivers for the touch-screen interface are included on the MD-224 software CD. To install a driver, simply insert

the Driver CD into the computer and select the operating system.

Once the driver is installed you may start using the MD-224 touch-screen feature.
