Hi

With the PLX-DAQ can it be used to send data only from MS Excel to a data bus. Any examples of this.
Wan to send data to an old TMS1000 processor. No need to acquire info from the device.

Thanks

PLX-DAQ is intended to receive data to Excel from a microcontroller with a serial port. It doesn't send data from Excel.

You'll need to write your own Excel macros to do what you want. You'll also need to use some kind of UART, probably with a MAX232 to convert the RS232 voltage levels to logic level, attached to the TMS1000 to receive the data from your PC. FTDI does make USB serial to 8-bit parallel adapters (http://www.ftdichip.com/Support/Documents/DataSheets/Modules/DS_UM232H.pdf) that you could use instead of a UART/MAX232.
