RS232 a. b.
Format: .txt Settings: i. BaudRate: 9600; Data: 8; Stop: 1; Parity: None
Ethernet: a. The transfer of a PDMS data via Ethernet is occurred by generating an XML file with the equivalent content of the transmitted data via RS232 and transfer to the PDMS server based on Secure Copy - scp Secure with Shell - SSH authentication. b.
The PDMS Server must have the functionality of SSH Server – Secure Shell Server. The copy function is implemented in an external script to make the transfer flexibly adaptable. The default configuration Provides that a defined user (Username: mipmmms, Passwort mipmmmspdms) is configured on the server. The transferred PDMS file is in home directory of this user (/home/mipmmms/YYYYMMDDHHMMSSpdmsxml.txt).
c.
After successful establishment of the PDMS-Ethernet transfer the PDMS-files are stored continuously in 10second intervals in the home directory of the user mipmmms on the PDMS server: /home/mipmmms/YYYYMMDDHHMMSSpdmsxml.txt. YYYYMMDD contains the current date and HHMMSS the current time according to the field contents of the file PDMS.
Protocol for the RS232 and Ethernet output
Data are transmitted via the configured RS232 interface in the service menu every 10 s in string format. The mean values must be transmitted.
The data are transmitted connectionless to the PDMS servicer. There is no error handling. Mammendorfer Institut für Physik und Medizin Filename: Service_Manual_M3_V2.1

Troubleshooting
DO NOT OPEN OR REMOVE THE TESLA M3 UNLESS YOU MUST ACCESS INTERNAL COMPONENTS AS INSTRUCTED IN THIS MANUAL. Once the Tesla M3 has been opened, the unit must undergo Safety Functional Test and Calibration Procedure (see Appendix A). The appropriate tests must be performed before the unit can be returned for use.
4.1. Preliminary Diagnostic Procedure There may be times when the system is suspected of a malfunction when, in fact, it is fully operational. This can be the result of human error, failure of other equipment, poor connections, and so on. Always follow the common sense procedures presented below before attempting any lengthy diagnostics or repair actions. It will save time and avoid needlessly taking the system apart. 1. Inspect the AC/Main power cord for possible damage. 2. Test the outlet for proper voltages. 3. Ensure that the AC/Main power cord is securely plugged into an electrical outlet and into the back of the unit. 4. Inspect Line Fuses in Fuse Holder. If either fuse has failed, replace. If fuses continue to fail, perform further diagnostics. 5. Make several attempts to recreate the problem including applying and removing power a number of times. If the problem does not reoccur, perform Safety Functional Test and Calibration Procedure (see Appendix A). If system passes all tests, return the system for use. If result of Section 4.1 – Preliminary Diagnostic Procedure, does not solve the problem, proceed to detailed troubleshooting described below.
