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 first 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 console port. Baud rate selections are 57600, 19200, 9600, and 4800. Parity selec-
tions are odd, even, and none. Format selections are Sysplex, Truetime, EndRun, EndRunX, NENA
and NMEA.
View and Change the Serial Time Configuration
Use the
cpuio
command to view the optional outputs on the CPU Module. This command will list
any connector that has an optional I/O signal. Connectors are identified as A, B or C. Use the
sys-
temio
command to view the Serial Time configuration.
Command:
cpuio
Sonoma reply:
CPU I/O A - SERIAL TIME OUTPUT is Installed
Current Setting = (See systemio command)
Command:
systemio
Sonoma reply:
System I/O Signal SERIAL TIME OUTPUT is Installed --
Current Serial Time Output Baudrate Setting = 9600
Current Serial Time Output Format Setting = SYSPLEX
Current Serial Time Output Parity Setting = ODD
Current NMEA Sentence 1 Setting = NONE
Current NMEA Sentence 2 Setting = NONE
Current NMEA Sentence 3 Setting = NONE
Use the
systemioconfig
command to change the Serial Time settings.
Command:
systemioconfig
Sonoma reply: Interactive script is started so you can change the Serial Time settings.
Sysplex Format
“Sysplex” means SYStem comPLEX and is a term used to describe computing on clusters of comput-
ers. The Sysplex option is designed to provide time synchronization for an IBM Sysplex Timer. It
can also be used for precise time synchronization by any computers that do not use NTP and have an
available serial port connection. The time contained in this string format is always UTC time. The
following string is sent once each second:
<SOH>DDD:HH:MM:SSQ<CR><LF>
