Commands accepted by the Module
All commands have a one or two byte structure. They are also sent to the module with 9600 baud. The
commands are sent in ASCII format.
Basic Bandwidth of ECG amplifier (Diagnostic or Monitoring mode):
„F“ Parameter: "0" or "1"
„0“ bandwidth of the amplifier DC-80 Hz Diagnostic mode (bear in mind mains filter setting)
„1“ bandwidth of the amplifier 0.67-40 Hz Monitoring mode (reset value)
„S“ extra strong filter, lower edge frequency 2 Hz
Transmission frequency of the waveform packet:
„S“ Parameter: "0", "1", "2" (0x53 0x31 for example for „S1“)
„0“ send waveform packets 300 times per second
„1“ send waveform packets 100 times per second (reset value)
„2“ send waveform packets 50 times per second
Amplification of the waveforms
„A“ Parameter: "0“, "1“, "2" or "3" (0x41 0x31 for example for „A1“)
„0“ Amplification stage 1 (lowest amplification, should be scaled to 0.5 cm/mV)
„1“ Amplification stage 2
„2“ Amplification stage 3 (highest amplification, should be scaled to 2 cm/mV)
Each amplification stage has double the sensitivity of the previous stage
Channel selection (1 wave channel can be selected)
„G“ Parameter: "0", "1" or "2" (for Einthoven III, II or I selection)
Filtering of the waveforms for 50 and 60 Hz line frequency:
„5“ 50Hz Filter on
„6“ 60 Hz Filter on
Selecting the transmitted waveform:
„D“ Parameter: „0“ or „1“ (0x44 0x30 for example for „D0“)
„0“ Show ECG trace (reset value)
„1“ Show respiration waveform (optional respiration board needed)
Calibration mode (1mV rectangle transmitted for 250 samples):
„C“ output 250 samples of 1 mV rectangular waves, then go back to normal mode
Simulated data outputs (useful for testing or exhibitions):
„M“ use simulated output waves and values
„N“ use real input for data transmission (reset value)
