Hi There,

Please can you show the data tab of your component? what trigger values are you using?

I haven’t communicated with biopac via parallel port before but have via serial port - sharing incase helpful alternative:

Begin exp:

import serial
ser = serial.Serial('COM3', 115200, timeout=1)
ser.write("RR".encode())

Begin routine

ser.write('10')
ser.flush()

Thanks,
Becca
