Do not make assumptions on PC connectivity
I will explain more about the complete application later but I want to concentrate on the specifics 1st.
There is a GPS that has a NMEA USB output that I want to harness the information from and connect to a NON PC serial port device.
AGAIN IT IS A NON PC DEVICE
So what I want to know is if anyone has ever taken a USB output (NOT FROM A PC) and converted it to a straight SERIAL.
I would like to take this USB connection and connect it to a PC with a TRUE (DB9/25) COM 1,2,3,4 SERIAL port on a PC to read the NMEA sentences as a means to test and verify connectivity.
I know I could just connect the USB to the PC and all would be well but the ultimate device that the USB would be connected to is a DB9 SERIAL port that can handle high speeds but WILL NOT BE A PC and drivers can not be loaded into it.
I know there are USB to serial cables that will take care of the physical connections and that may be the answer but under normal circumstances they are to be used from a USB PC to a serial device and the require a driver to be loaded on the PC.
This application that I am speaking of can not use a driver or ultimately a PC for connection.
GPS---w/USB---->-----SERIALPORT---ON A PC (for testing)
Now for the ultimate application...
I am trying to see if there is a way to take a GPS with a dedicated NMEA USB output (these are fairly uncommon and usually do not have displays) and then connect it to a Uniden BCD996T/XT for control.
The application goes a step further but I will get into that as (if) the discussion progresses.
I will be testing the USB output later this week or early next week.
If you tell me to get a USB to Serial cable and plug the USB into a PC I will give you unhappy faces and make fun of you for not reading the post
