>>Summer time
From SW 5.34 version — automatically setting the interval of summer
time validity. The line start contains the month and day,
when summer time starts, the line end contains the month and
day when it ends In this range the difference between GMT maintained in the CU and the local time, saved
in the Time (z)one, is increased by 1 hour. The value of
GMT remains without changes and the local
time visible in the menu (s)ervice (t)ime or in the
menu (s)ervice (s)tatus is shifted.
The time changes in such a way that in the day designated by
line start at 02:00:00 the local time is shifted to 03:00:00
and in the day designated by line end at 03:00:00 the local
time is shifted back to 02:00:00. Considering the inconstancy of the start
and end data for the validity of summer time approximate data is inserted
into the items start and end which can be corrected individually.
When the year entry is changed in the CU when setting the time using
the (s)ervice (t)ime menu, then new initialisation should be
performed in the menu (U)nit (e)dit.
| Time (Z)one for DST: EU | — Time Zone Calendar for Day Light Savings
|
| Time zone DI(F)F: 3600 | — difference between the local time and GMT, without influence of Daylight Savings |
| Time (z)one: -3600 | — The number of seconds which should be added to the local time to get GMT. |
Time sync
Time synchronisation messages schedule. Time-sync messages are used to synchronise the calendar time in adjacent units in a MORSE network. Two modes are used:
A unit periodically requests the calendar time from a node in the neighbouring unit. This mode is mostly used, as it allows more units to be synchronised from one source.
(i)n:0 — No of the node which originates the time-sync request message
Sr(c):0000000 — address of the time source
(p)eriod:0 — period of time-sync requests (in seconds)
A unit periodically transmits the time-sync message to the configured destination, to synchronise the calendar time in the unit which contains the destination node address. This mode saves the request message, but it is limited to one destination synchronised from one source.
(O)ut:0 — No of the node which originates the time-sync message
ds(t):0000000 — an address in the unit to be synchronised
p(e)riod:0 — period of time-sync messages (in seconds)
Power saving (SLEEP MODE)
From HW version 4.1. and SW 7.06 the modem MR400 can be
set to the idle SLEEP mode, where power consumption drops to 2.5mA. The
transition into SLEEP mode is accomplished using command (m)isc
p(o)wer save or by sending service packet E02A 0001 0000
0000 1FD5. It is possible to return back to the active state in
three ways:
when the preconfigured time elapses
by putting the data signal to SCC2 or SCC3 port
by interrupting the power supply for 15 sec or more
For a detailed description see : www.racom.eu, Support, Interface Protocols, Sleep mode.
| alar(m) time:0s | – the time over which the modem stays in SLEEP mode, 10 to 3600 sec. Since fw 10.0.89.0 and hardware version 7.1 (produced since 07/2009) the alar(m) time was enlarged to 10 – 86399 sec. |
| m(o)de:0000 | – 0001 – both the radio and modem part switch to SLEEP mode – 0000 – only the radio part switches to SLEEP mode |
