TCP TC/TM Data Link¶

Connects to a TCP socket, sending telecommands and receiving a stream of telemetry.

Class Name¶

org.yamcs.tctm.TcpTcTmDataLink

Configuration¶

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

dataLinks:
 - name: tctm
   class: org.yamcs.tctm.TcpTcTmDataLink
   tmStream: tm_realtime
   tcStream: tc_realtime
   host: 127.0.0.1
   port: 10010
   commandPostprocessorClassName: org.yamcs.tctm.GenericCommandPostprocessor
   packetInputStreamClassName: org.yamcs.tctm.CcsdsPacketInputStream
   packetPreprocessorClassName: org.yamcs.tctm.GenericPacketPreprocessor
   packetPreprocessorArgs:
       timestampOffset: 2
       seqCountOffset: 10
       errorDetection:
         type: "CRC-16-CCIIT"

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 TCP port to connect 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.
packetInputStreamClassName (string): Class name of a Packet Input Stream. Default is org.yamcs.tctm.GenericPacketInputStream configured to read 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.
