Connector-Specific Properties

Every connector has its own custom set of properties. The properties you configure for a TCP Listener will be different from a Database Writer and so on. Here is a list of source and destination connectors supported by Mirth® Connect: Source Connectors Channel Reader DICOM Listener Database Reader File Reader HTTP Listener JMS Listener JavaScript Reader TCP Listener Web Service Listener Destination Connectors Channel Writer DICOM Sender Database Writer Document Writer File Writer HTTP Sender JMS Sender JavaScript Writer SMTP Sender TCP Sender Web Service Sender Additional connectors are made available as extensions: Email Reader Serial Connector NextGen Results CDR Connector FHIR Connector Interoperability Connector Suite Parent topic: Connector Components

MLLP Transmission Mode

This transmission mode implements the Minimal Lower Layer Protocol (MLLP) specified by HL7, and is often used when transmitting HL7 v2.x messages. There are two versions of MLLP, v1 and v2. The first version is similar to the Basic TCP Transmission Mode in that it only specifies sequences for the start/end message bytes. The second version builds on the first with "reliable delivery assurance", by having each system send a protocol-level ACK or NAK immediately after every received frame. By default only MLLPv1 is enabled, as it is the most common use-case. Item Name Default Value Description A Start of Message Bytes 0x0B <VT>) The MLLP Start Block bytes before the beginning of the actual message. Only valid hexadecimal characters (0-9, A-F) are allowed. B End of Message Bytes 0x1C0D (<FS><CR>) The MLLP End Data/Block bytes after the end of the actual message. Only valid hexadecimal characters (0-9, A-F) are allowed. C Use MLLPv2 No Select Yes to use the MLLPv2 bi-directional transport

Frequently Asked Questions

This section addresses the most common questions users have about Mirth® Connect by NextGen Healthcare. What is Mirth® Connect? Mirth® Connect is a versatile, standards-based healthcare integration engine that speeds bi-directional message routing, filtering, and transformation between disparate health-info systems over various messaging protocols (e.g., HL7, X12, EDI, DICOM, XML). Is Mirth® Connect the same as "Mirth"? Yes. Mirth 1.0 was released in 2006 by WebReach, Inc. Based on the success of the Mirth application, WebReach, Inc. was renamed "Mirth Corporation" in 2009. To avoid confusion between the new company name and its products, the Mirth application was renamed Mirth® Connect. As of early 2016, Mirth Corporation, as a business entity, no longer exists, having been absorbed into the Quality Systems, Inc. family of products in Sept. 2013. QSI has since become NextGen Healthcare, and Mirth® Connect lives on with other former Mirth Corporation products as part of the "Mirth Solu

TCP Sender

This destination connector opens a new TCP client connection and sends messages over it. You can decide whether to keep a connection open, and if so for how long. Configurable transmission modes allow you to decide how to send outbound messages and receive responses. Supported property groups: Destination Settings Item Name Default Value Description A Transmission Mode MLLP The transmission mode determines how to send message data out on the socket byte stream, and how to receive responses. For additional information, see TCP Listener B Sample Frame <VT> <Message Data> <FS><CR> This is dependent on the Transmission Mode and displays an example of how an outgoing message frame is expected to look. C Mode Client Client: The TCP Sender will initiate new connections outbound to a remote server, and then send messages outbound on that connection. Server: The TCP Sender will open a server socket and listen for incoming connections. If queuing is enabled, messages will continue to queue until

Listener Settings

These properties are shown when the connector is a TCP socket-based listener (server), and allow you to specify the local network interface and port to listen on. Supported connectors include the DICOM Listener, HTTP Listener, TCP Listener, and Web Service Listener. Item Name Description A Local Address If All interfaces is selected, the connector will listen on all interfaces, using address 0.0.0.0. If Specific interface is selected, the connector will listen on the specific network interface address given in the accompanying field. B Local Port The TCP port on which to listen for connections.
