Software Protocol Description
The normal connection to the board is done via serial, asynchronous communication. Both CMOS and
RS232 (+/- 5Volt level) voltage levels are available. The device uses one of two protocols. The protocol is
selected by the installed software version.
Protocol 1:
The first protocol is the original protocol which ensures backwards compatibility of the board in existing
devices. This protocol is token oriented. Special marker bytes that are not present in the normal data
stream mark the meaning of the following byte.
Protocol 2:
The second protocol is designed follwing the protocol of the EG05000. This protocol is able to communi-
cate the respiration data together with the selected ECG signal, if a respiration board is fittet to the ECG
module.
For details please see the protocol descriptions on the following pages.
The RS232 voltage levels are helpful during evaluation of the board, which can be done using a PC and
a special software. The connection in the customer’s final system could be done through 0V/5V levels,
which saves parts on the customer’s side of the data stream.
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.
