Figure 10 OS-Gemini Home Page
Elapsed Time Indicator The elapsed time indicator attribute presents the total time in days,
hours, minutes and seconds since the last system restart. The system can restart for several
reasons, e.g. commanded reset from the system reset webpage, or a power cycle of the
equipment.
System Clock If the SNTP (Simple Network Time Protocol) (see section 6.3.6.3) is enabled a
system clock attribute is displayed giving the date and time of the last page refresh. If SNTP is
disabled then the system clock attribute is not displayed on the home page.
6.1.1 Home Page Alarm Display
The home page is also used to display all outstanding major system alarms. The following
major system alarms are defined:
Unit Calibration The unit calibration alarm is raised if the OS-Gemini unit fails to detect a valid
set of calibration data in the unit’s non-volatile memory.
Install Status If any errors are detected during the installation process, the unit will
automatically raise an audible alarm. The install status alarm will be raised with an appropriate
reason code, e.g. the alarm will be raised if an incorrect target MAC address is specified for the
peer OS-Gemini wireless unit.
ARQ Is Not Configured ARQ must be enabled on both ends of the Point-to-Point link. This error
message is generated if there is a mismatch in the ARQ settings between both ends of the link.
