<strong>Universal</strong> <strong>channel</strong> <strong>switching</strong> <strong>circuit</strong> <strong>and</strong> <strong>The</strong> <strong>Overall</strong><br />
<strong>Structure</strong> <strong>of</strong> <strong>Fcar</strong> <strong>Auto</strong> <strong>Diagnostic</strong> <strong>Scanner</strong><br />
In actual use, different vehicles can use the same<br />
diagnostic connector, such as OBD II, but pin <strong>of</strong> diagnosis<br />
signal might be distributed in different pins. In order<br />
to be compatible with different pins, output connector<br />
DB15 internal connection <strong>channel</strong> <strong>switching</strong> matrix <strong>of</strong> auto<br />
diagnostic tool can realize arbitrary <strong>switching</strong> <strong>of</strong> 2-way<br />
13 <strong>channel</strong>s through <strong>channel</strong> <strong>switching</strong> matrix..<br />

<strong>Fcar</strong> automotive fault diagnostic scanner adopts dual ARM<br />
chip architecture, <strong>and</strong> lower computer using 32-bit signal<br />
processing chip ARM7, running speed up to 60MIPS. <strong>The</strong> upper<br />
computer adopts high-speed 32-bit ARM920T chips, running<br />
speed maximum to 200MHZ, can quickly <strong>and</strong> effectively<br />
process data from ECU. <strong>Fcar</strong> auto diagnostic tooladopts<br />
high-capacity SD card as storage media for program <strong>and</strong> data,<br />
which facilitates data saving <strong>and</strong> program upgrade, but<br />
also easy to exchange data between vehicle<br />
diagnosticequipment <strong>and</strong> PC. In addition, the application<br />
<strong>of</strong> touch screen in the diagnostic scanner also greatly<br />
facilitates the users to operate the scanner.
