USB->serial TEST

[Bloody-orc]

Hello.

Just out of interest i did that test on my computer and saw, that the Voltage is -8 (LED off) and +8V (LED on), so my USB serial shouldn't work... but infact it does just fine... is this the test's problem or is it just luck?

Sounds like you did the test without the PICAXE chip in the socket! The test should be done with a PICAXE chip present and powered, measuring the voltage on the PICAXE pin.
