Heart rate averaging, section 201.7.9.2.9.101 b) 3) Response to irregular rhythm, section 201.7.9.2.9.101 b) 4) A1) Ventricular bigeminy: the EG01010 counts both large and small QRS complexes to display a rate of 80 bpm. A2) Slow alternating ventricular bigeminy: the EG01010 counts both large and small QRS complexes to display a rate of 60 bpm.
Page 10 For single (ventricular-only) pacemaker pulses with normally paced QRS-T, with 0.1 and 2.0 ms pulse- widths and ± 2 mV and ± 700 mV pulse-amplitudes, the EG01010 correctly displays heart rate of the QRS-T rhythm (60 bpm for the specified test waveform).

Connector JP1 is compatible with the interface connector on Medlab’s EG05000 five channel ECG OEM board. Therefore, test cables that have been built for this board can also be used for the EG01010 board. Version 1.06...
Page 12: Serial Transmission Protocol 1
Medlab medizinische Diagnosegeräte GmbH EG01010 User Manual Serial Transmission Protocol 1 All data is transmitted at 9600 baud, 8 bits, 1 stop bit, no parity. Each time a pulse is detected by the board's internal algorithm, a block with a new, averaged pulse rate is transmitted. The pulse detector is of high quality, and the point in time where the pulse marker (0xFA) is transmitted can be used for triggering applications that require to synchronize other devices to a patient's R-wave.
Page 13 Medlab medizinische Diagnosegeräte GmbH EG01010 User Manual 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“...

EG01010 can be connected directly to a PC, the received data is shown on the screen. To run the program, connect the EG01010 board to the serial port of a PC. If the PC has no serial port, please use a USB to RS22 adapter and install the driver of this adapter first and make sure to create a virtual serial port.

To reduce overhead for the waveform transmission, the wave block uses another checksum algorithm as the status and value blocks do. The EG01010 works with a three lead cable. The board contains a lead-off detection that gives information about a non-connected electrode.
Page 17 Medlab medizinische Diagnosegeräte GmbH EG01010 User Manual Transmitted blocks: There are three types of regular data packets, waveform blocks, value blocks and status blocks. Beginning of a packet is indicated by the marker 0xF8 (wave), 0xF9 and 0xFA (values) and 0xFC (status). Every other transmitted byte has a value of less than 0xF8. This allows for easy synchronisation.

Page 19 Medlab medizinische Diagnosegeräte GmbH EG01010 User Manual bytes are transmitted in this block. Type == 00 → not used Type == 10 → respiration value Type == 01 → pulse value Type == 11 → not used, but reserved for future extensions The checksum is the sum of all bytes in the block, with byte 2, the chksum itself, ignored for the sum.

Page 22 60601-2-27 requires different detection ranges for adults and neonates. See page 8 "QRS detection", for details. The EG01010 complies with all requirements of the new (and the old) standard. The board powers up in adult mode, the firmware is therefore compatible to the older versions that did not have a neonatal mode.
Page 23: Test Program For Protocol 2
For the second protocol the test program of the EG05000 is to be used. To run the program, connect the EG01010 board to the serial port of a PC. If the PC has no serial port, please use a USB to RS22 adapter and install the driver of this adapter first and ensure to create a vir- tual serial port.
Page 24: Regulatory Considerations
Therefore, the EG01010 has not been - and also cannot be - CE-marked. The customer has to undertake the procedure of CE-marking the final product that contains the module. However, several products on the market have successfully passed this certification using this OEM module.
