Acquisition Modules and Platinum Firmware

Networking Configuration

software (using the command RTSTATUS ENABLE). They are automatically
enabled if the digitiser is ever configured via the interface in Platinum.

Acquire approximate time from connected GPS: This check-box tells the

system that a GPS receiver has been attached to one of the serial ports and is
to be used as a clock source. The serial port used must be configured with a

“Port function” of “NMEA in. Receive GPS data for NTP” and, when used
with Güralp supplied GPS receivers, must be set to 4,800 baud operation, as

described in 9.6 on page 124. No further configuration is required.

Note: This setting should only be used on CMG-NAMs and

CMG-NAM64s.

Server address: Allows a number of Internet or network-accessible NTP
servers to be listed for use as clock sources. You can specify these servers by

either IP address or hostname. If names are used, they must either be listed in
the local hosts file (/etc/hosts) or resolvable via the Domain Name Service
(DNS). Clicking the

button on any row will open a new, blank row. In

the same way, rows can be deleted by clicking the corresponding

button.

7.4.2 Configurable parameters in expert mode

The only difference between standard and expert mode on this screen is the
addition of a Server options column to the NTP servers table.

This text field can be used to provide additional control over how the NTP

daemon uses the server. The options are described in the standard ntp.conf
manual page, available on-line at

http://linux.die.net/man/5/ntp.conf

.

7.5

Email configuration

Platinum firmware is capable of sending system alerts via email over the

Internet or over a local area network.

This feature is currently unused but is provided for future expansion.
