Instacal assigns serial number 0 to our USB-1408FS Plus OEM board and our Visual Basic program cannot initialize the board. If the firmware is renamed from USB-1408FS.hex to USB-1408FS-Plus.hex and downloaded, Instacal assigns the board serial number 117, our Visual Basic program appears to initialize the board, but the board does not function properly.
Is there a USB-1408FS-Plus.hex firmware file available that should be used, or are we doing something wrong?
