I recently purchased a Stimtracker and would like to test the emulated serial port interface using Windows Hyperterminal. After reading through this page:
Thank you. I am now able to communicate with the Stimtracker. When I send a command, (“mhff”, for example) the ‘marker’ light illuminates for a short time, so I assume the Stimtracker is receiving my command.
The issue I’m having now is that my EEG amplifier (Brain Products) is not detecting any of the events I am sending. I have connected the USB2 adapter box to the stimtracker using the cable you have provided. Triggers from the photostimulators are being detected perfectly, I’m just having a problem with events sent through the serial interface.
Kris, the ‘mh’ command takes a binary value, not hex. However, ‘mhff’ should have still turned on a couple of lines. Try ‘mhoo’ to have two additional lines turned on (makes it easier to spot changes in the Brain Products software).
I am using the commands
Serial.Writestring “mh”
Serial.WriteInteger &HFF
One more thing: I noticed how the baud rate has been changed to 115k on the website, but there is a note underneath that still says the factory default is 110k.
