4. Service terminal

The Service terminal is a program used for handling the CU of the MORSE system by a personal computer. It allows the setting of CU parameters, the monitoring of traffic on individual channels, the running of tests, the reading of records about past traffic and other functions. It is part of the applications group for handling a MORSE network and is accessible on

Choose Download>Software on the main page or Download>Archive for the older recomended versions and choose the appropriate directory:

  • utils/actual/ – here we find the current control applications file for the CU. According to the operating system in use we select the appropriate file; for Windows the file is utils-win-gui- Number indicates the software version and this number incrementally increases with development.

  • firmware/actual/ – firmware modules contained in radio modems; these do not need to be loaded as one of these modules is already loaded at manufacturer. Next work with the firmware see the article Download.

  • utils/release-candidate/ – these directories, accessible at higher levels of access via the Internet, contain new, not fully tested software

After choice utils/actual/ next menu appears:

Menu utils/actual

Since the version the .exe file is avilable, here utils-win-gui- It is suitable for the automatic installation into PC. Copy the file in the PC and start it. If you reply NO after request about backup, then the old Utils set will be overwritten. If the reply is YES, then it is saved in the directory Utils-xxxx. The directory c:\Racom\Utils\ containing all important files is created. Setr can be started also from the Windows Start menu Start>Programms>Racom>Utils>Setr.

The other possibility is to use the file Unpack it into suitable directory. This sub-directory contains more files, however the absolute minimum requirement for work with the CU is setr.exe.

Files with firmware modules for the CU can be downloaded from directory firmware/actual/. The directory contains two sets of modules:

  • files (formerly are designed for MR25, MR25ET, MCM302

  • files (formerly are designed for MR900, MR400, MR300, MR160, MC100, MG100

Create the subdirectory \fkl\ into directory c:\Racom\Utils\ and unpack in it the needed files from Here it is e.g. ce10.fkl and cb10.fkl. Example of the location of files:

For controlling the CU we use utility:

SetrSoftware for controlling the CU
MemcpLoading software to the CU
NetcnfUpload/download CU configuration
NetlockLocking the CU

For a description of downloading a firmware program module to the CU please see, section Support/Software/Utils/Download firmware.


For problem-free configuration and control of the CU we recommend using the same version of firmware in the CU and control utilities (Setr, Memcp and others).

A service cable serves for connecting the PC to the CU and has contacts connected in the following manner:

Service cable DKR23 for MR400, rx and tx signals

Fig. 4.2: Service cable DKR23 for MR400, rx and tx signals

Service cable DKR12 for MR25

Fig. 4.3: Service cable DKR12 for MR25

For connecting the CU to the PC using a serial cable connect the SERVICE connector of the modem to port COM1 or COM2 on the PC. Also see Service manual, chapter service connector.

Now we can start Setr.exe. If the service cable is connected to the PC via another port than com1 then we run Setr with the appropriate parameter, e.g. setr -p2. The service terminal screen then appears. Above there is the Setr version number ( ver. ), at the lower edge there is the address of the connected node in the CU and the number of the PC port. The main content of the screen is the MORSE main menu, from which it is possible to fully control the CU.

For the duration of the connection of the service cable port SCC0 is disconnected from the physical interface, the default parameters (19200 bit/s, N81, protokol MARS-A) are set automatically and communicates via the service cable to application Setr (or Netcnf, Memcp…). The communication with user equipment connected to SCC0 connector is recovered after disconnecting the service cable.

This functionality performs SCC0 in MR400 or SCC2 in MR25.
