	* What's the pin-out of the board? Guessing from a forum post, the longest trace (rightmost in the board photo) is GND, then going left VCC, TX (as in "data coming from the LSPro", considering it's a DCE), RX (as in "data entering the LSPro"). So the colours in the photo with the usb connector are: Green-GND, Yellow-TX, Orange-RX (as before, considering the LSPRO as a DCE, so TX means out of the LSPro and RX into the LSPro). Am I right?		* What's the pin-out of the board?

New page

This page is confusing. Too high a pictures to words ratio (e.g. not enough description).

Questions:

* I've managed to work out this is a USB-RS232 bridge chip, but we seem to end up with USB connectors at both ends. Huh?
* Where does this connect on the LS Pro?
