Console access is a fundamental building block when working with the LeapFrog Pollux Platform family of devices. It gives you the ability to list files, run scripts and programs, and generally look around inside the Linux operating system running on the device. A few items are needed, most notably an RS232 to TTL level shifter (MAX232) if you want to use the serial port on your PC to connect to the device, or, since those are getting scarce these days, a USB to Serial converter, something like an FTDI cable.

Software Needed

Terminal - TeraTerm, Minicom, Hyperterminal, Cutecom, etc will do.

Hardware Needed

Cartridge to break out the UART pins on the connector. Or hardwire to internal connections

RS232_Level_Shifter or FTDI type USB to TTL serial adapter. 3.3v versions are preferred.

Connecting w/o Cartridge

If you don't have a cartridge that breaks out the necessary connections, and you're good with a soldering iron, you can carefully solder on the necessary wires to the internal connections. Then bring the wires out to your serial adapter of choice.

TX, RX, GND, and VCC soldered directly to the pins.
