Amulet Hotkey K4u
+
Manual
11 When the update completes, the results are written to the
local and remote log files. See section 6. 7.
Also, the oneShotUpdateResult registry value (see step 7)
now indicates the update outcome. Possible values are:
0 No firmware update performed yet
2 Firmware update not needed
3 Firmware update successful
4 Firmware update failed
5 User cancelled firmware update before it started
8. 4 Remote scheduled firmware updates (USB)
This section describes how to schedule a firmware update for
multiple K4u
+
units. These updates require you to pre-edit
registry values on each source computer.
Note:
For any individual K4u
+
, you must only use one instance
of Mouse Point for scheduled firmware updates. If a user has
multiple Mouse Point instances running (one on each
computer attached to their K4u
+
), we recommend that you
only enable scheduled updates for one of these instances.
Important!
A user must be logged on to the source
computer when a scheduled update runs. If you want to
update multiple K4u
+
units outside of office hours, you
need to manage this requirement. For example, if users
lock their source computers without logging off before
they go home, the firmware update will run successfully.
1 Designate a network folder to store the .pkg files containing
firmware updates. This folder must be accessible from each
remote source computer.
Notes
●
Do not save multiple firmware packages in this folder.
If Mouse Point detects multiple packages, it only
installs the first package that it finds, which may not
be the package containing the latest firmware.
●
Similarly, do not save one-shot update files in this
folder. Any one-shot firmware update installed from
this folder will be overwritten when the next scheduled
update runs.
2 Using your preferred deployment method, make the
following registry changes on each remote source computer.
3 Locate the following registry key:
HKLM\Software\Amulet Hotkey
\USB updating config
4 In this registry key, edit the following registry values:
enableScheduledUpdates
Set this value to Yes to enable scheduled firmware
updates. Set it to No to disable scheduled updates.
If Mouse Point is installed on multiple computers
attached to a K4u
+
, you must only enable scheduled
updates on one attached computer. For example, set this
registry value to Yes on one computer; set it to No on all
other attached computers.
forceFocusForUpdates
Note:
Firmware updates can only run if the source
computer has focus when the update starts.
Set this value to Yes to enable the source computer to
acquire the K4u
+
focus, if required. You need to do this if
there is a risk that another computer attached to the
K4u
+
has focus when the update is due to start.
When this registry value is set to Yes, the K4u
+
changes
focus automatically to the source computer if no mouse
or keyboard activity is detected on other attached
computers. After the update has been applied, the K4u
+
reverts to the original channel.
If the K4u
+
cannot change focus to the source computer,
or if this registry value is set to No, the scheduled update
times out and fails.
RemoteUpdatePath
Set this value to the full UNC path of the folder you
chose in step 1. This folder contains the .pkg files for
scheduled firmware updates. For example:
\\UNX-NY-01\Amulet Hotkey\Switch Firmware
scheduledUpdateTime
Set this value to the time (in 24 hour format) when you
want firmware updates to run each day.
Leading zeroes for hours and a colon separator between
hours and minutes are both optional. Valid examples are
01:45, 1:45, 0145 and 145.
Note:
A random delay of between 1 and 10 minutes is
applied to the start time to alleviate network
congestion in environments where many K4u
+
units
need to be updated at the same time.
5 At the scheduled update time, the firmware update runs
automatically.
A warning dialog displays a 30 second countdown. This
allows any user working on the source computer at that
time to cancel the firmware update.
