netconfig
This command starts an interactive shell script that will allow the user to configure the IP network
subsystem of the Tempus LX. By default, the unit is configured to configure itself using the Dynamic
Host Configuration Protocol (DHCP). If you need to set up static IP configuration, you must run
this script as
root
from the RS-232 serial I/O port during the installation process. Refer to
Chapter 2
- Using netconfig to Set Up Your IP
for details on the use of the command.
This script creates or modifies these files:
/etc/HOSTNAME
,
/etc/hosts
,
/etc/networks, /etc/resolv.conf
and
/etc/rc.d/rc.inet1
. All of these are non-volatilely stored in the FLASH disk
/boot/etc
directory.
You must re-boot the Tempus LX after running this script for the changes to take effect.
Set:
netconfig
Tempus LX response:
Interactive shell script is started.
ntpconfig
This command starts an interactive shell script that will allow the user to configure the NTP subsys-
tem of the Tempus LX. By default, the unit is configured to authenticate its replies to clients using its
default MD5 keys in the
/etc/ntp.keys
file. If you need to create your own MD5 keys (recommended)
or set up broadcast/multicast operation, you must run this script as root. Refer to
Chapter 2 - Con-
figuring the Network Time Protocol
for details on the use of this command.
The two files that are modified are
/etc/ntp.keys
and
/etc/ntp.conf
. Both of these are non-volatilely
stored in the FLASH disk
/boot/etc
directory. You must re-boot the Tempus LX after running this
script for the changes to take effect.
Set:
ntpconfig
Tempus LX response:
Interactive shell script is started.
setantfltmask
This command allows the user to enable or mask the GPS antenna fault. Parameter for this command
is either MASKED or ENABLED. Setting this command to MASKED will prevent the antenna
fault from creating an alarm condition. Some installations may need to mask this fault due to special
antenna situations like splitters or DC blocks that confuse the antenna detection circuit. The factory
default setting is ENABLED.
Set:
antfltmask MASKED
Meridian response:
Antenna Fault Mask set to MASKED
setgpsdynmode
This command accepts a single argument: ON or OFF to allow the user to set the dynamic mode of
operation of the GPS subsystem. By default, the unit is configured for static operation, so this setting
is OFF. If the Tempus LX will be mounted on a moving platform, like a ship, then this setting must
be changed to ON. The change takes place immediately and is stored non-volatilely.
Set:
setgpsdynmode ON
Tempus LX response:
GPS Dynamic Mode is ON.
setgpsrefpos
This command starts an interactive shell script that will allow the user to set the accurate, reference
