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

TCP Transmission Modes
The transmission mode determines how to receive message data from the incoming byte stream, and how to send responses out. The following transmission modes are supported on the TCP Listener / TCP Sender (and Serial Listener / Sender extension): Basic TCP Transmission Mode MLLP Transmission Mode An additional transmission mode is made available via an extension: ASTM E1381 Transmission Mode Parent topic: TCP Listener

Basic TCP Transmission Mode
This transmission mode allows you to specify basic TCP frame data (beginning and ending byte sequences). This allows the source connector to know when a message has been fully received. Destination connectors also use these sequences when sending data outbound. Item Name Default Value Description A Start of Message Bytes The bytes before the beginning of the actual message. Only valid hexadecimal characters (0-9, A-F) are allowed. B End of Message Bytes The bytes after the end of the actual message. Only valid hexadecimal characters (0-9, A-F) are allowed. If this is not specified, the only way a connector knows whether a message has been received is if the socket timeout is reached or if the remote side closes the socket.

The s section to the right of the transmission mode dialog allows you to easily drag-and-drop bytes into the components to the left, without having to remember the actual hexadecimal values. These also show up as labels next to the byte fields: Parent topic: Basic TCP Transmission Mode

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
