I have a computer running Windows 2000 on it. Had windows 5.1 loaded on it and was communicating via RS232 out serial port to a UMAC 1050 board to collect/transmitt analog and digital signals. Hard drive crashed and have installed new one. No backups and trying to restore computer. Reinstalled labview from disk but can't get Umac to talk. Any drivers needed or sample programs to test it?
