Serial Port Debug
<p>[TOC]</p>
<h3>I. Summary Description</h3>
<p>Serial port debug, mainly used to check whether the hardware and software functions of the device work, as a necessary condition for serial port connection to peripherals, to help troubleshoot problems encountered in the process of docking peripherals.</p>
<ul>
<li>Support for the automatic detection of RS-232.</li>
<li>Support for detection of RS-485 connection to external tools.</li>
</ul>
<h3>II. Conditions of use</h3>
<ul>
<li>The device has serial port functionality.</li>
<li>The serial port is connected properly.</li>
</ul>
<h3>III. Detailed operation</h3>
<ul>
<li>
<h4>RS-232</h4>
</li>
</ul>
<p>1， The device preview screen is accessed via the remote control by pressing <strong>INFO</strong> to enter the system information page.</p>
<p>2， Enter the system information page and press <strong>SQUARE</strong> or <strong>F1</strong> for simple tips and instructions.</p>

<p>3, after connecting the line, press start, start the serial test, press stop, terminate the serial test;.</p>
<p>4, if it is a 232 type serial port, you can directly short the transceiver line manually, and you can view the test results on the menu.</p>

<h4>RS-485</h4>
</li>
</ul>
<p>485 type serial port requires <strong>485 to 232 converter</strong> + <strong>USB to serial port cable</strong> + <strong>PC</strong> + <strong>PC serial port debugging assistant software</strong> for cooperative testing.</p>
<p>1, open the provided serial debugging assistant tool.[UartAssist.exe](<a href="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&sign=96bd56ac680dae231f1d6eca1b4987bb">http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&sign=96bd56ac680dae231f1d6eca1b4987bb</a> "[UartAssist.exe")；
2, the computer desktop, find my computer - right-click my computer - Properties - Device Manager.</p>

<p>3， in the UartAssist, select the serial port number of your computer.</p>

<p>4， Select the baudrate as<strong>115200</strong>.</p>

<h3>IV. Common Problems</h3>
<ul>
<li>Enter test and click send data, if the wiring is correct, the device will respond with an ok character and the serial port test page will show normal. If it does not display, it means the serial port is abnormal (theoretically, the probability of serial port abnormality is very small, most of them are wiring problems or 485 to 232 converter problems).</li>
</ul>
