Odd Triggers Appearing

Hey All,

Me again. I have run my exp and I have exported the data as a 'Tab delimited ASCII' file and then run it through a Jupyter notebook, filtering out all of the data without triggers and I've noticed that, whilst the triggers being sent through to the trigger box (MindMedia - Nexus Trigger Interface), they are quite odd.

I have sent through triggers using the following codes:

Open Connection

import serial

exp.serial_port = serial.Serial('COM4', baudrate=115200, bytesize=serial.EIGHTBITS)

Write Triggers

exp.serial_port.write('target'.encode('utf-8'))

All of the triggers being sent through are the same except for the 'target' label. Some have been labelled as 'filler', or standardad (standard ad), or dynamicad, or radiolistening, but the export looks like the below, with WingDings-type characters.

Just wondering if anyone has experienced things like this before and whether there is a way to fix it?

Thanks!

EDIT: I've noticed that the first trigger being sent for each event is the first letter of the label that I've given the trigger (i.e. dynamicad = d). But this still doesn't explain why the whole word doesn't appear, nor why the primary trigger is accompanied by all the other notations.
