I had a Data I/O 29B with a serial interface and I assume your Pro-Log is similar. Cabled up and baud correct you should get a menu on a CR with your host. Mine took an Intel or Motorala ASCI HEX string on power up without any commands or prompts. Randy

I have everything needed, but how can I get the data in? There is a serial interface, did anybody have some program for a standard PC to handle that daa transfer? Cabling istn't an issue, can do it. Thanks for helping. With best regards Gerhard
