I have a competition timing system with Photocells and an ALGE TIMING S4 Stopwatch. I also have the TIMY3 version. Both versions have a USB connection and inform the elapsed times of the competitions.

I am finding many difficulties to communicate the timer with VMIX. There is an application that records the timer information in an excel spreadsheet but it is not in real time. I need to manually save the excel file so that it can read on VMIX.

I need an API or some connection that is more direct between the USB timer and VMIX.

Anyone experiencing this problem?

Studying more about this timer communication, I saw that I will have to develop an application to be able to extract this information. Unfortunately Excel is not the best solution, because while the program is accessing Excel to write the times, Vmix cannot read the file until I click on save.
This is extremely unpleasant and will not work as quickly as I need it.
I found an application that listens to the serial port and writes a csv file and Vmix can read immediately after communication.

However, the data needs to be processed, because the port reading has some data that I don't care about and VMIX ends up copying all the content.

I'm going to look for an application that makes this communication more focused on what I need.

You need to filter more your csv file (an example would have been nice) or write your own application .
You mention an application that reads the serial port so it should be no problem to write one as you already have the serial info needed and can chack what it writes which you could intercept and filter before the actual writing
It's pretty simple overall , we do that for other timing systems that send serial data



is why their docs mention the protocols for their serial communications as its simple to pick from it what one needs , hence they make it or they use/pay their complete hard and software for it
