UDP TC/TM Data Link¶

Sends telecommands via UDP socket, receiving telemetry on the same socket pair. The data link acts as the UDP client. No telemetry is received unless a command was sent first (any command).

Class Name¶

org.yamcs.tctm.UdpTcTmDataLink

Configuration¶

Data links are configured in etc/yamcs.instance.yaml. Example:

dataLinks:
 - name: csp-bridge
   class: org.yamcs.tctm.UdpTcTmDataLink
   tmStream: tm_realtime
   tcStream: tc_realtime
   host: 127.0.0.1
   port: 10010
   commandPostprocessorClassName: org.yamcs.tctm.csp.CspCommandPostprocessor
   packetPreprocessorClassName: org.yamcs.tctm.csp.CspPacketPreprocessor

Configuration Options¶

tcStream (string): Required. The stream where outgoing data (telecommands) is emitted
tmStream (string): Required. The stream where incoming data (telemetry) is emitted
host (string): Required. The host of the remote system
port (integer): Required. The UDP port to send to
commandPostprocessorClassName (string): Class name of a Command Postprocessor implementation. Default is org.yamcs.tctm.GenericCommandPostprocessor.
commandPostprocessorArgs (map): Optional args of arbitrary complexity to pass to the command postprocessor. Each postprocessor may support different options.
packetPreprocessorClassName (string): Class name of a Packet Preprocessor implementation. Default is org.yamcs.tctm.IssPacketPreprocessor which applies ISS conventions.
packetPreprocessorArgs (map): Optional args of arbitrary complexity to pass to the packet preprocessor. Each preprocessor may support different options.
