Download and Apply Updates on Next Boot
: When the oMG boots, it
automatically applies any updates that have been downloaded. This is
the default option.
·
Download and Apply Updates during Scheduled Time (UTC time
without DST)
: If any updates have been downloaded, the oMG will apply
them during the ‘scheduled time’:
·
Attempt Upgrade
: How often upgrades can be installed:
·
Just Once—Only on the scheduled date and time slot
·
Every Day—Each day beginning on Start From
·
Every Week—Once per week beginning on Start From
(e.g. 17 May 2017 is weekly attempts on Wednesdays)
·
Every Month—Once per month beginning on Start From
(e.g. 17 May 2017 is monthly attempts on the 17th)
·
Start From
: First day that updates can be applied. If date is last day
of the month, ‘every month’ upgrades will be on the last day of each
month.
·
Between
: Time slot (UTC times) during which updates can be
applied. (DST adjustments are not applied to the time slot.)
Note: In cases where the unit is never shut off (i.e. when a vehicle is in operation 24 hours
a day, 7 days a week), use the ‘Scheduled Time’ upgrade option to install updates.
•
Burn BIOS
: when enabled, installs updates to the system's BIOS.
•
Ignition Shutdown Delay Override
: the oMG only performs updates when
the ignition is turned on. Should the ignition be turned off during an update,
this option will override the Uptime Extension After Ignition Off shutdown
option (see
on page 91) by the number of hours specified.
Note: Care must be taken when specifying a value. If not enough time is specified then the
unit may turn off before the update is complete. If too much time is specified, then the
vehicle's battery may be drained.
•
Download Bandwidth Limit
: sets the maximum bandwidth (in KB/s)
available for downloading updates over the WAN link. This can be used to
ensure that adequate bandwidth is available for regular communications over
the WAN.
•
Download Timeout
: the amount of time (in seconds) after which the failure to
receive data should be considered to have timed out. In this case, the
download operation will stop and continue the next time the gateway comes
online again. This field is useful for slower links which may require larger
values when dealing with large files or when dealing with a bad link that
frequently jumps between being offline and online.
•
Download on High Cost Link
: when enabled, the oMG will download the
update even when a high cost WAN link is in use (e.g. a cellular connection).
By default this option is disabled, since most updates are done on a "low
cost" link such as a WiFi access point within a vehicle depot. Note: if
bandwidth consumption is a concern (e.g. due to cost) then set the cellular
