Hi Guys,
I've just tried to connect one of these to my ATTOpilot V3.
I hooked it up like this......
ATTO TTL to RS232
Telm IN -------------------------------------------TX-O
Telm Out------------------------------------------RX-I
GND------------------------------------------------GND
VCC (3.3V input)
The 3.3V is scaled down from 5V like this.
I can't seem to get it to work?
Am I missing something?
Should I connect is differently?
It works great with a FTDI (USB) but I need it to work from a DB9 RS232.
(I want to try it over IP as I have a great little IP to serial converter that I use allot at work)
Thanks in advance!
Scott

Hi Scott!
Do the Tx or Rx LEDs come on?
Can you check that your 3.3V is in fact 3.3V when it is all powered up - I am worried that using a voltage divider to power a device will not give very good results.
Cheers,
Andrew.
