Alix2c3 COM output doesnt work…

hubsd

hello

i just bought an alix2c3 board, i try to connect using windows terminal, teraterm, putty but nothing shows (settings 38,400, 8 bit, Parity: None, Stop: 1 bit, Flow control: None)

first, i used a USB to RS-232 adapter (prolific chipset) then i used an old computer with COM1/COM2 but i still cant see anything in terminal etc…

when i plug the DC adapter i can see 3 green leds, then only 1
also, all 3 ethernet ports shows a green led

is my board defective?

thx

Most likely not - have you tried a null-modem cable?

I use a USB to Serial adaptor on my laptop to "talk" to Alix boards all the time but have a Cisco serial cable between the adaptor and the Alix serial port - it is a null modem cable.

If you take a look at the ALIX documentation, you'll see on page 9:
@http://pcengines.ch/pdf/alix2.pdf:

Connect serial port to a PC through null modem cable (RXD / TXD crossed over).

The USB to serial adaptor is just a "normal" com port.
As long as the gender changes is not designed as null modem it wont work.
