Communication RS485 & Ethernet
38 Revision R09, November 2016
With a
set<SPACE>16:ResetSettings=1<CR><LF>
command you can restore all parameters to their factory settings.
The command RSN restarts the network. This has to be done whenever the net-
work setting has been changed like the IP address, the DHCP mode,... The new
settings will be used only after a RSN or a RST command.
set<SPACE>16:RSN=1<CR><LF>
8.2.5 Changing the logging time dt(s), date & time
set<SPACE><RS485No>:dt(s)=30<CR><LF>
The logging and reporting time is set to 30s. The internal measurement time is
always 1s. The logging and reporting time must be multiple of the internal meas-
uring time.
With the command
set<SPACE>16:DateTime=DD.MM.YYYY;hh:mm:ss<CR><LF>
you can set the date and time settings of the internal processing unit, where DD
means day, MM month, YYYY year, hh hours, mm minutes and ss seconds, ref-
erenced to GMT zone (Greenwich Mean Time).
Example:
set 16:DateTime=13.04.2006;17:22:46<CR><LF>
will set 13
th
April 2006 as the date and 17:22:46 GMT as the exact time.
The terminal software JO-DataClient has a build in update function for the time
called „
–utcupdaterate <hours> “ (chapter 11.10). If the ceilometer is connected
to a WAN or LAN and the NTP option is active, time settings over the serial inter-
faces shall be avoided.
8.3 Data Queries RS485
At any time during operation, the CHM 15k is in one of the following transfer
modes as shown in table 7.
Changes in transfer mode can be made using the command
set <RS485NO>:TMO=x
as described in chapter 8.2.2 or by using the direct input in the web interface.
For example:
