6 NTP Software Installation and Configuration
6.7.1 Create the Configuration File
The NTP configuration file, NTP.CONF, should be located in the
/
ETC directory.
The window below shows a simple configuration file declaring a
Acutime NTP reference clock and a network time server in the
Trimble.COM domain. The Acutime NTP reference clock is declared
as unit #1.
A maximum of four Acutime NTP reference clocks can be connected
to any UNIX host. Valid unit numbers on UNIX systems are 0–3. The
next section examines the use of the unit number in mapping to
physical serial ports on the host system.
The /
ETC/DRIFT file is used to record information about the onboard
system’s intrinsic frequency error. For more information on this
feature, please refer to NTP documentation .
