Chapter 9 Utility Functions. PRELIMINARY Release MSD Software Manual.

In the inspect mode it is possible to press the [PRINT] key. When this key is

pressed the session log is transmitted on the RS232 port on the MSD. It is

possible to connect a serial printer directly to this port. Another option is to use

a terminal program on a computer.

The communication settings are as follows:

9600 Baud.

8 Data Bits.

No Parity.

1 Stop Bit.

No Handshake.

9.4 DCF-77 Real Time Clock. 

If the MSD is fitted with a General Purpose I/O Module it is possible to use the

MSD as a DCF-77 Real Time Clock. Please see appendix A.1.8 for further

details about the General Purpose I/O Module. When the [CLOCK] function is

enabled the MSD will show three small windows on the screen. If a DCF-77

Receiver is connected to pin 19 on the General Purpose I/O Module, the MSD

is able to decode this signal and show the time and date on the screen in the

topmost window. When the clock window is selected for the first time after a

reboot the clock will count seconds from zero. Within two minutes the clock will

be synchronized to the DCF-77 time signal. If the [CLOCK] menu is exited

after synchronization the MSD will still show the correct time. The MSD can

only be synchronized while the [CLOCK] menu is selected. The MSD has also

included two stopwatches which is controlled using the [START], [STOP] and

[RESET] keys.
