d odometer. My question How can connect these 3 sensors to COM1? Also, I need to take the GPS time every 1 sec and put this time to the odometer and Gyroscope output? By the way, records from Odometer and Gyroscope every 0.1 sec. Thanks in advance, MahmoudHi Mahmoud,
Another option you may wish to consider is to increase the number of serial ports available on your laptop. For example, you can obtain a PCMCIA card that has additional RS-232 ports. National Instruments has a 4-port PCMCIA RS-232 card available, which can be found on ni.com by going to
Products & Services > Instrument Control and Connectivity > Serial Interfaces > PCMCIA > PCMCIA-232/....
With this expansion, you will be able to connect each RS-232 device to its own port, and then interface that within LabVIEW. Other options could be to convert the serial interface into another protocol, such as USB (as previously suggested) or Ethernet.
Hope this helps!
