4<h2>What is this?</h2>
5<p>
6This is an RS232 converter for interfacing a PC with an Archos Jukebox (or any other device with a 3.3V serial port). It converts the PC serial port signals to 3.3V levels. The design is very straightforward, using a standard MAX3232 transceiver.

8<h2>How to power it the easy way</h2>
9<p>
10It takes its power from the DTR signal in the serial port, so the communication software in the PC must set the DTR signal ACTIVE for this to work. It might still not work on some laptops, that may have a weak driver for the DTR signal.

13<h2>How to power it the safe way</h2>
14<p>
15If your PC is a laptop or otherwise might risk having too little power in the serial port, it is also possible to take power from the USB port or another 5-10V source. Just remove the D1 diode and connect the power to the +5V and GND pads.
