4.1.3 No Serial Output or Serial Output Incorrect
Description
•
The connected systems are not receiving a serial string or
•
The connected systems are receiving serial strings with a time which is at variance
with the system
Cause / Solution
•
The serial interfaces are not configured correctly (e.g. transmit on request only, UTC
output, incorrect baud rate etc.).
•
The connection to the serial interfaces is not correct (e.g. TxD and RxD lines
transposed).
4.1.4 Incorrect Time Output
Description – Local Time
•
Local time
transmitted is at variance with the actual local time
Cause / Solution
•
UTC/Local time offset not set or set incorrectly
•
ST/WT changeover points of time not set or set incorrectly
•
Time was set manually, system running in quartz mode
•
Time has drifted as the system has been running in quartz mode for a lengthy period
Description - UTC Time
•
UTC time
transmitted is at variance with the actual UTC time
Cause / Solution
•
Time has drifted as the system has been running in quartz mode for a lengthy period
•
Time was set manually, system running in quartz mode
Cause of incorrect UTC time when setting manually: incorrect local time entered (the
local time must always be entered when setting)
or the system was configured incorrectly (time offset, ST/WT changeover)
4.1.5 No ST/WT Changeover
Description
•
“daylight saving time“ (summer time) does not appear on the display
•
The bit for “daylight saving time“ (summer time) is not set under status in the data
strings.
Cause / Solution
•
Changeover points of time not set or set incorrectly
•
Output/display was configured for UTC and not local time
