Change the Serial Time Settings
On the front-panel display traverse to the Main Menu and then to Sys_I/O. If a Serial Time output is
installed in your unit, then there will be a selection for SerTimeOut. Select this and you will be able
to change the format, baud rate and parity.
Or, you can use these console port commands:
Command:
systemio

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>
<SOH> is the ASCII Start-of-Header character (0x01)
DDD is the day-of-year
: is the colon character (0x3A)
HH is the hour of the day
MM is the minute of the hour
SS is the second of the minute
Q is the time quality indicator and may be either:
<space> ASCII space character (0x20) which indicates locked
? ASCII question mark (0x3F) which indicates
the unsynchronized condition
<CR> is the ASCII carriage return character (0x0D) and is the on-time
character, transmitted during the first millisecond of each second.
<LF> is the ASCII line feed character (0x0A)
