Configure the settings for the LLP Listener source component.

The LLP Listener component listens on a specified port for HL7 messages using the LLP protocol.

From here you can choose the message encoding type, choose LLP delimiters, enable port sharing, enable connection timeouts, enable IPv6 support, configure ACK message settings and enable SSL.

• Click the Edit Channel button
• Enter your settings and click Save Changes

Message encoding

• Choose the desired encoding from the Message encoding list box
• Check Escape 8-bit characters in ACKs (HL7) to escape 8-bit characters in ACK messages

LLP delimiters

•  (Optionally) choose custom LLP delimiters

Port

• Specify the port number In the Port field
  By default Iguana will automatically choose a port that is currently not in use, if you want to choose a port number manually you can check the used ports in Dashboard > Ports
  
• Check Enable port sharing to allow multiple LLP Listener components to use the same port
• When Enable port sharing is selected, connections can use a Remote host and an optional Alternate host:
  

Connection timeout

• Check Connection timeout to enable connection timeouts
• Enter the number of minutes to wait before timing out (defaults to 30minutes)
  

IPv6 support

• Check IPv6 support to enable this channel to connect to a client using IPv6
  If the checkbox is not showing then you will need to enable IPv6 support on your server

Ack

• Select Fast for Iguana to automatically generate ACKnowledgment messages
• Select Translator or Legacy VMD if you want to generate custom ACKnowledgment messages
  
• Choosing Translator adds a Script to the LLP Source to generate custom ACKs
  
• Choosing Legacy VMD uses the autoack.vmd by default, but you can choose a different VMD
  

Use SSL

• Check Use SSL to receive messages securely using SSL (Secure Socket Layer)
• Select the Private key file, this must be in PEM format and cannot be password protected
• Select the Certificate file, this must be x509 in PEM format and cannot be password protected
• Check Verify Peer to verify the server sending you messages, and enter the name of the Certificate authority file, which must be x509 in PEM format and cannot be password protected
  
• You can use the view certificate link to view the certificate details:
