pluginopts
This command displays the current settings for the installed plug-in option boards.
Query:
pluginopts
RTM3204/Tycho response:
Digital Buffer, 2001-0004-012-NC is installed.
Port A Current Setting = 10M PPS.
Port B Current Setting = 10M PPS.
Port C Current Setting = 10M PPS.
Port D Current Setting = 10M PPS.
pluginoptsconfig
This command starts an interactive shell script that will allow the root user to change the settings of
any installed, user-selectable, plug-in option board outputs. The user-selectable outputs are all board-
specific.
Set:
pluginoptsconfig
RTM3204/Tycho response: Interactive shell script is started.
setgpscaldelay
This command starts an interactive shell script that allows the user to change the clock calibration
delay. This setting is used to advance or retard the clock in order to compensate for antenna cable
length or other external hardware. Allowable range is +500000 to -500000 nanoseconds.
Set:
setgpscaldelay
RTM3204/Tycho response: Interactive shell script is started.
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 RTM3204 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
RTM3204/Tycho response:
GPS Dynamic Mode is ON.
setgpsrefpos
This command starts an interactive shell script that will allow the user to set the accurate, reference
position of the RTM3204/Tycho. By default, the unit is configured to locate itself using the GPS
satellites. In some situations, visibility of the sky is limited and the unit will not be able to determine
its position. In this case, the user must determine an accurate WGS-84 position by other means and
input it using this command. If you need to set the accurate reference position, you must run this
script as root. The changes take place immediately. If the GPS dynamic mode setting is ON (see
gpsdynmode
/
setgpsdynmode
commands), then running this script will have no effect.
In addition to setting a new accurate, reference position, the user can also invalidate an existing one.
This will force the RTM3204 to re-establish a new reference position using the GPS satellite constel-
lation.
Set:
setgpsrefpos
RTM3204/Tycho response: Interactive shell script is started.
