INTRODUCTION
The MT-503A HDMI and 3G/HD/SD-SDI Bi-directional scaler Converter with 3.5” LCD Monitor,
Audio Embedder/Extractor & local loopout is an advanced HDMI and SDI cross-conversion monitor
with multi-format and multi-pattern support. Not only can it receive signals, the MT-503A can also
extend HDMI or SDI input signals through SDI loop-out. It is equipped three buttons and a 3.5” panel to
ease the control. With a 3.5” panel, the output signal can be monitored and controlled through OSD,
such as resolution and image adjustments. This device can also be used as a tool for eye diagram
scanning to check the quality of the SDI cable input. In addition, it provides a variety of test patterns,
which can be used as a simple pattern generator. The MT-503A provides a cost effective way to the
monitor video devices and displays.
