Guralp Systems CMG-DCM build <10,000 - Manual (Page 85)

Acquisition Modules and Platinum Firmware Networking Configuration
order to synchronise external equipment, such as a CMG-DM24 digitiser
module. This technique is described in section 9.6 on page 124.
The NTP subsystem displays its status in a panel of the “System status”
display of the web interface. This panel includes the current system date and
time, the lock status, estimated error and current clock source.
Platinum systems support two distinct timing modes, NTP and Manual. NTP
is recommended for nearly all installations. Manual mode requires that the
system clock be set from the command-line at least once per day and is, by its
nature, considerably less accurate than NTP mode.
To configure NTP from the web interface, select:
Configuration → Data handling → Timing
or
Configuration → All options → Networking → Network Time Protocol daemon
To configure NTP from the command line, start gconfig, select “Networking”
from the top level menu and then select “ Network Time Protocol (NTP)
daemon”.
7.4.1 Configurable parameters
The configurable parameters for timing are presented in three tabs: General,
NTP and Manual.
