Introduction

7" Touchscreen display kit M2

The M2DIS is an optional display unit with touchscreen which can be installed internally in the front panel of the M2 Multi–Media Digital audio mixer. This unit consists of a 7" TFT display panel with a resolution of 800 x 480 px that is fitted with a resistive touchscreen panel. It is controlled by a powerful 32 bit processor which communicates directly with the DSP processor.

This unit allows the user to operate the control and configuration functions of the matrix system without any external equipment. This can be useful for direct access, when the system is installed in a technical room where no external control devices are within reach or in case the system is not connected to a LAN network due to security reasons.

Touchscreen precautions

• Tap the touchscreen gently. Never use force.
• Don't use any sharp object to tap the touchscreen. Don't use a pen, but only use your fingertips or stylus especially meant for use with touchscreens.
• Keep the touchscreen dry and clean. Don't use any abrasives or cleaning solutions to clean it. Only clean it with a soft damp cloth.
