Thanks Martino, I gave it a try, no luck. I get no response from the board at all. I even put an RS232 analyser in line with the board and there is no data activity on the RX side. I am assuming the board is dead. :( I have just ordered an S-Series X-Board to replace it. Thanks anyway for your help

I have a VFD2041 that has been in storage for a little while, and now i cant get it to communicate with any PC. Using Uproject it will open to comm port but no data will flow. I have tested the serial port and i works fine, I have 5v at the board. I have tried using the manual override jumper also. ...
