Appendix
I
Software Options
Your Meridian II supports software options. Software options are the RTIC Option described in
Chapter 11 - Real-Time Ionospheric Correction (RTIC) , and the Precision Time Protocol described
in Chapter 9 - PTP/IEEE-1588
.
This appendix is about viewing or enabling software options, using
the PTP Option in the examples below.
Normally, EndRun products are configured from the factory with software options enabled. But
software options are also field-installable. In other words, you can enable a software option yourself,
after you have received your Meridian II. First you must obtain an 8-digit license key from EndRun
Technologies, then you can enable it using the
wrt_sw_opt
command.
wrt_sw_opt
To enable a software option use this console port command. You must be logged in as the root user
in order to run this command and you must provide a license key on the command line. If the key is
verified, then the option will be enabled.
Command:
wrt_sw_opt [key]
MeridianII reply:
Option to be enabled is PTP0 Daemon
get_sw_opts
This command shows which software options are enabled in your Meridian II. The command returns
a 32-bit value with each bit identifying a software option. See Software Option Bit Definitions be-
low. Here is an example when no software options are enabled:
Command:
get_sw_opts
MeridianII reply:
00000000000000000000000000000000
Bit are numbered from 0 to 31, from right to left. This example shows bit 0 set which identifies that
the PTP0 option is enabled.
Command:
get_sw_opts
MeridianII reply:
00000000000000000000000000000001
installed_sw_opts
This is another command that shows which software options are enabled. Below is an example:
Command:
installed_sw_opts
MeridianII reply:
The PTP0 Daemon is Installed.
The Real-Time Iono Corrections Option is Installed.
