Sample Messages: HL7 minimal lower layer protocol

HL7 minimal lower layer protocol

HL7 Outbound messages are framed using the HL7 Minimal Lower Layer

Protocol. This protocol is documented in the HL7 2.6 specification. All HL7

messages begin with one start block character. The framing is completed by an

end character and a carriage return character at the end of the message. The

general format is as follows:

Where:

<SB> = Start Block character (0x0B)

<EB> = End Block character (0x1C)

<CR> = Carriage Return Character (0x0D)

<HL7 messages> use UTF-8 character encoding.

The following pages provide the general format of the various HL7 data

messages recognized by the monitor for outbound interface. This document

describes only the data fields and segments that are provided by monitor. Fields

and segments not listed here are not sent by monitor.
