Thread: Serial port pulse signal

Do you have the RS232 protocol spec for that GPS device?

I'll have to apologise in advance, all of my experience in programming is in numerical data analysis, and that is not the focus of my issue.

To put things into context - I've got a scientific instrument that attaches to a PC and captures data at 4Hz. I want to integrate this data capture with a GPS device. The GPS device can accept pulses through an RS232 port in order to initiate a new data capture. My idea was to send a pulse via the PC's RS232 to the GPS's RS232 every time a new file is dropped into the working directory.

Could anybody help / lead me in the right direction?

Thanks in advance!

1. Get the specification as already suggested.
2. Check if the device comes with some API/utility library/whatever to ease communication with external software.
3. Depending on above and your additional requirements pick the programming language and other tools (e.g., a 3rd party library for RS-232 communiation).

Remember that the more specific you are, the more specific answers you will get.
