2.5.5 COM 1 – Connection for serial data transmission<br />
The COM1 port (RS232) on the front of the recorder is used (as a service interface) for maintenance<br />
of the device or for connecting external devices such as a GPS receiver or modem.<br />
The interface (D-SUB 9, male) is configured as standard for RS232:<br />

5 GND System Ground<br />
6 DSR Data Set Ready<br />
7 RTS Request to Send<br />
8 CTS Clear to Send<br />

Note that the only navigation systems and GPS receivers supported are those recommended by<br />
<strong>DResearch</strong>. The GPS receiver can be connected directly to the COM1 port. The port parameters can<br />
be configured in SystemManagement ���� GPS. (See Chapter 3, Configuration)<br />

Power<br />
The device will be switched on when a high<br />
power level is at Pin 3 "Ignition High Side"<br />
(min. 6 V). PIN 4 has to be connected to<br />
the return potential (ground).<br />
The service interface allows analysis of the device using a terminal. This should only be carried out by<br />
authorised experts. This requires the use of a fully wired serial service cable from <strong>DResearch</strong>.<br />
