TCP TM Data Link¶

Provides packets received via plain TCP sockets.

In case the TCP connection with the telemetry server cannot be opened or is broken, it retries to connect each 10 seconds.

Class Name¶

org.yamcs.tctm.TcpTmDataLink

Configuration¶

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

dataLinks:
 - name: tctm
   class: org.yamcs.tctm.TcpTmDataLink
   stream: tm_realtime
   host: 127.0.0.1
   port: 10011
   packetInputStreamClassName: org.yamcs.tctm.CcsdsPacketInputStream
   packetPreprocessorClassName: org.yamcs.tctm.GenericPacketPreprocessor
   packetPreprocessorArgs:
       timestampOffset: 2
       seqCountOffset: 10
       errorDetection:
         type: "CRC-16-CCIIT"

Configuration Options¶

host (string): Required. The host of the TM provider
port (integer): Required. The TCP port to connect to
stream (string): Required. The stream where incoming data (telemetry) is emitted
packetInputStreamClassName (string): Class name of a Packet Input Stream. Default is org.yamcs.tctm.CcsdsPacketInputStream which reads CCSDS Packets.
packetInputStreamArgs (map): Optional args of arbitrary complexity to pass to the PacketInputStream. Each PacketInputStream 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.
