-The OBSW supports sending PUS TM packets via TCP or the PDEC IP Core which transmits the data as CADU frames. To make the CADU frames receivabel by the [TMTC porgram](https://egit.irs.uni-stuttgart.de/eive/eive-tmtc), a python script is running as systemd service on the flatsat PC which forwards TCP commands to the TCP server of the OBC and reads CADU frames from a serial interface. The PUS packets transported with the CADU frames are extracted and forwared to the TMTC program's TCP client. The code of the TMTC bridge can be found [here](https://egit.irs.uni-stuttgart.de/eive/tmtc-bridge). To connect the TMTC program to the TMTC-bridge a port forwarding from a host must be set up with the following command:

+The OBSW supports sending PUS TM packets via TCP or the PDEC IP Core which transmits the data as
+CADU frames. To make the CADU frames receivabel by the
+[TMTC porgram](https://egit.irs.uni-stuttgart.de/eive/eive-tmtc), a python script is running as
+`systemd` service named `tmtc_bridge` on the flatsat PC which forwards TCP commands to the TCP
+server of the OBC and reads CADU frames from a serial interface.
+
+You can check whether the service is running the following command on the flatsat PC
+
+```sh
+systemctl status tmtc_bridge
+```
+
+The PUS packets transported with the CADU frames are extracted
+and forwared to the TMTC program's TCP client. The code of the TMTC bridge can be found
+[here](https://egit.irs.uni-stuttgart.de/eive/tmtc-bridge). To connect the TMTC program to the
+TMTC-bridge a port forwarding from a host must be set up with the following command:
+
+```sh
 ssh -L 1537:127.0.0.1:7100 eive@2001:7c0:2018:1099:babe:0:e1fe:f1a5 -t bash
-````
+```
-Note: The encoding of the TM packets and conversion of CADU frames takes some time. Thus the replies are received with a larger delay compared to a direct TCP connection.
+
+You can print the output of the `systemd` service with
+
+```sh
+journalctl -u tmtc_bridge
+```
+
+This can be helpful to determine whether any TCs arrive or TMs are coming back.
