sounds like that rules out a USB adapter. The LED blinking when daa is sent indicates the cable is functioning. Mismatched baud rates is the usual cause.
-Are you using the db9 cable direct to your PC or are you using any USB adapter?
I tried both of them, but they have the same problem.
-Have you tried using a different com port?
Yes, I tried using COM2/COM8…
-you can also try checking the jumpers. might be faulty~?
I removed the VL=VS1 jumper.
If the MAX232 chip is bad, then the SSC-32 board could be considered to be bad, since this component is not socketed. The MAX232 chip is a communications interface device and it’s possible it could be defective which is why the LED blinks but nothing happens, regardless of baud rate settings used.
I would do as Jonny (innerbreed) suggested to send the board back and get a replacement.
I will contact them today, but I’m going to need more information. I can’t go to Active Robots and say yellowfish needs a new controller. Send me an email with your info.
