ASTM communication protocol
The cobas e 411 analyzer employs ASTM communication protocol.
Communication data structure
ASTM communication protocol consists of three layered data structure such as
message, record, and frame. Data is communicated by message. Further, data is
communicated by frame actually. Data structure of a frame varies by protocol.
(1) Elecsys type A message consists of multiple records. A record consists of one or more
frames. A frame comprises not more than one record. In case a record exceeds
240 bytes, a frame is divided into middle frames and a last frame. [ETB] is used
for the middle frame and [ETX] is used for the last frame.
(2) cobas type A message consists of several records. A record consists of one or more frames.
A frame may comprise multiple records. In case of a record exceeds 240 bytes,
a frame is divided into middle frames and a last frame. [ETB] is used for the
middle frame and [ETX] is used for the last frame.
