TABLE 21 Connectivity Map - Lower Layer Protocol
Name Description
LLP Type MLLP is the configured default value.
The lower layer protocol (LLP) type. Select one of the following options:
■ MLLP (Minimal Lower Layer Protocol)
■ HLLP (Hybrid Lower Layer Protocol)
■ MLLP v2.0 (Minimal Lower Layer Protocol v2.0)
For more information on the available envelope types, see “Lower Layer
Protocol” on page 23 .
Start Block Character The first envelope marker character in the HL7 envelope, as a decimal ASCII
number. Enter a number from 1 to 127. Unless there is a conflict, the value should
be ASCII VT (decimal 11).
End Data Character The second to the last envelope marker character in the HL7 envelope, as a
decimal ASCII number. Enter a number from 1 to 127. Unless there is a conflict,
the value should be ASCII FS (decimal 28).
End Block Character The last envelope marker character in the HL7 envelope, as a decimal ASCII
number. Enter a number from 1 to 127. To strictly comply with the HL7
Standard, this property must be set to a carriage return (decimal 13).
HLLP Checksum Enabled An indicator of whether the HLLP Checksum is enabled or disabled.
Select true to enable checksum values; otherwise select false.
Max Number of Retries The maximum number of times the adapter tries to send a message upon
receiving the MLLP v2.0 Negative Commit Acknowledgement from the peer
before giving up. This property is used by the adapter in outbound mode. Enter
any integer.

Outbound Adapter
The following table lists and describes the property that appears on the Sequence Number
Protocol page of the Properties Editor accessed from the Connectivity Map. This property
enables or disables HL7 sequence numbering, which is used to help prevent duplication of data.
TABLE 22 Connectivity Map - Sequence Number Protocol
Name Description
Sequence Number
Enabled An indicator of whether sequence numbering is enabled or disabled. Enabling
sequence numbering helps prevent duplication of data. Select true to enable
sequence numbering; otherwise select false.
