Here you will find extra Windows software downloads like a serial dll and examples how to use it to send markers from a PC.
Please take care to close the VU-DAMS configuration screen before starting your experiment!
One more important note (especially for testing the markers); you can make VU-AMS recordings without putting on electrode stickers or even without connecting the ECG/ICG electrode cable. You will only record noise but will be able to open the 5FS file in VU-DAMS to check if all event markers are stored.
You could even disable the triple beeps you get because of the out of range physiological signals via the Warning button in the configuration window. But don't forget to turn them back on!
The DLL should be automatically installed with the VU-DAMS suite

In Presentation you could use the run_process function to call the AMS.exe program below run_process("C:\AMS.exe", "COM1 AMS5fs 1 1") assuming AMS.exe is in C:\ and VU-AMS is connected via COM1
Use AMS.exe [COMport] [AMStype] [Marker] [Beeping]
Example: AMS.exe COM1 AMS5fs 23 0
'remote' written in E-Prime to be operated by researcher
Markers can be sent from a PC running E-Prime via a wired connection to the VU-AMS device
