View the DDS Connector
On the front-panel display traverse to the Main Menu and then to CPU_I/O. This display lists any
connector on the CPU Module that has an optional I/O signal. Connectors are identied as A, B or C.
Select the particular connector (I/O-A, I/O-B or I/O-C) to see which signal is installed.
Or, you can use this console port command:
Command: cpuio
Sonoma reply: CPU I/O C - DIRECT DIGITAL SYNTHESIZER OUTPUT is Installed
Current Setting = (See systemio command)
Change the DDS Rate
On the front-panel display traverse to the Main Menu and then to Sys_I/O. If a DDS output is
installed in your unit, then there will be a selection for DDS-Out. Select this and you will be able to
change the rate. Available pulse rates are 1 Hz to 10 MHz, in 1 PPS steps.
Or, you can use these console port commands:
Command: systemio
Sonoma reply: System I/O Signal DIRECT DIGITAL SYNTHESIZER OUTPUT Installed
Current Setting = 0 Hz
Command: systemioconfig
Sonoma reply: Interactive script is started so you can change the pulse rate.
Serial Time Output
This option is provided on an RS-232 (or RS-422) serial port labeled “Serial Time”. It is an output
that provides a once-per-second sequence of ASCII characters indicating the current time. The “on-
time” character starts transmitting within the rst 20 microseconds of each second. The output starts
automatically on power-up. See Appendix H - Specifications for details.
The Serial Time is a “system signal”. This means that there is one Serial Time signal that affects the
whole system. In other words, if your Sonoma has multiple Serial Time outputs, and you change the
settings, then all Serial Time outputs will be affected.
There are several different formats for this ASCII string. The format, baud rate and parity can all be
changed via the front-panel keypad or via the console port. Baud rate selections are 57600, 19200,
9600, and 4800. Parity selections are odd, even, and none. Format selections are Sysplex, Truetime,
EndRun, EndRunX, NENA and NMEA.
