UDP Out DAT
The UDP Out DAT is used to send information over a UDP connection to/from a remotely-located computer. Use the
send() methods of the udpoutDAT_Class to send messages.
Although is it an 'Out' node, it can receive reply messages from the machine(s) it sends to. The messages will appear in the DAT's contents (just like the UDP In DAT).
NOTE for Windows OS - If experiencing connection issues make sure Windows Firewall is disabled.
Parameters - Connect Page
protocol - ⊞ - Selects the network protocol to use. Refer to the Network Protocols article for more information.
- Messaging (UDP)
- Multi-Cast Messaging (UDP)
address - You can put an IP address (e.g. 100.123.45.78), or a machine name to send to. If you put "localhost", it means the other end of the pipe is on the same computer. If you are using multi-cast you should put the multi-cast address you want to send to here.
port - The network port to send to.
shared - Use the same connection as other networking DATs using the same network protocol.
format - ⊞ - Determines how the incoming data is parsed.
- One Per Byte
perbyte- One row is added to the table per byte received.
- One Per Line
perline- One row is added to the table per line received. The end of a line is delimited by \n, \r or a null character (\0).
- One Per Message
permessage- One row is added to the table per message received.
active - This check box enables the connection.
Local Port Mode
localportmode - ⊞ -
Parameters - Received Data Page
callbacks - The Callbacks DAT will execute once for each message coming in.
executeloc - ⊞ - Determines the location the script is run from.
- Current Node
current- The script is executed from the current node location.
- Callbacks DAT
callbacks- The script is executed from the location of the DAT specified in the Callbacks DAT parameter.
- Specified Operator
op- The script is executed from the operator specified in the From Operator parameter below.
fromop - The operator whose state change will trigger the DAT to execute its script when Execute from is set to Specified Operator. This operator is also the path that the script will be executed from if the Execute from parameter is set to Specified Operator.
clamp - The DAT is limited to 100 messages by default but with Clamp Output, this can be set to anything including unlimited.
maxlines - Limits the number of messages, older messages are removed from the list first.

Some operators have a DAT docked to them that contains some python functions. These functions, called "callbacks", get called when something in the operator changes.
