local

local time: 2005-09-01 15:12:45 LOC — value according to menu (s)ervice (t)ime (d)ay time with suffix LOC for local time (winter) or LTS for local summer time

uptime

uptime: 537 sec — time elapsed from hw reset, see sts menu

day

day time:2005-09-01 13:12:45 GMT — GMT time maintained in Communication Unit, see (U)nit (e)dit

log write at 86400s — time counted from hw reset in which the next log write will occur, see (U)nit (e)dit (l)og period

The unit status would also display warnings when the CU is in some exceptional state, e.g.:

All

All transmitting disabled! — non standard states messages

Test active on Node 1 — message about running some of tests on the node 1

Binmon: SCC2

Binmon: SCC2 — monitoring of serial channel

HEAP

remaining free space for auxiliary buffers. The table displayed shows the number of packets (buffers) waiting in different queues throughout the CU.

16.7. (t)ime

There are three sort of time used:

  • The GMT is used in the CU and is kept with a lithium battery. Effective life of the battery is minimally 15 years under normal operation. The life at disconnected supply is however 3 years only.

  • The local time valid on the CU station. This time is set by (s)ervice (t)ime. It is corrected by (U)nit (e)dit DI(F)F parameter to get the GMT, which is kept in the CU.

  • The distant operator time jis used by the operator, which can be situated in different time zone. It is obtained from GMT by subtracting of parameter -t, kwhich is found in the file Morse.par in the operator’s PC.

The local time us used in (s)ervice (t)ime menu and in transmitted old monitoring, which creates the monitoring message completely in the source node. The GMT is used in all other functions inside the CU, like saving time of logs, Events or time synchronization by (U)nit (e)dit Time sync.

The distant operator time is used for display of logs, Events and (new) Monitoring messages.

16.9. (c)lock info

The system clock frequency is measured in the course of four seconds with resolution in kHz. Caution! The CU is “dead” for these four seconds. In real operation, this action will cause an CU failure for four seconds. The signal from the on-board RTC (Real Time Clock) is used for measurement, so the accuracy of the clock value obtained cannot be better than the RTC accuracy.
