8. Updating the firmware
Amulet Hotkey periodically releases firmware updates for the
K4u
+
to add new compatibility or new features and to fix issues
reported by customers.
If you register on the Amulet Hotkey website, you can choose to
be notified about these updates and decide whether or not you
want to install them.
You typically update the K4u
+
firmware using a USB connection.
However, updates using a serial connection are also supported.
Both methods are simple and safe.
Important!
End-users must not switch channels while a
firmware update is underway because this will cause the
update to stop. This may leave the K4u
+
in an unstable
state; see section 8. 6.
8. 1 Firmware updates over a USB connection
You can install packages containing firmware updates from any
USB computer attached to the K4u
+
. In the following sections,
this is your ‘source computer’.
Three update methods are supported:
■ Local manual updates: Any user with access to the desktop
on the source computer can directly update the K4u
+
firmware by clicking Update Switch Firmware and FPGA via
USB in the Mouse Point menu. See section 8.2.
■ Remote manual updates: Administrators can update the
firmware for a specific K4u
+
by remotely editing the registry
on a remote source computer and invoking a ‘one-shot’
update. See section 8. 3.
■ Remote scheduled updates: Administrators can schedule a
firmware update on multiple K4u
+
units by pre-editing the
registry on each source computer. See section 8. 4.
Note the following requirements:
■ OS: Firmware updates over a USB connection are launched
from a source computer attached to the K4u
+
. Firmware
updates are only supported from source computers running
Windows XP or Windows 7.
■ Update package: For each update method, the firmware
update package can be in a local folder on the source
computer or on a network share that is accessible to Mouse
Point from the source computer.
■ Mouse Point: Firmware updates are driven by the Mouse
Point utility; see section 5. The source computer must
therefore be running the Mouse Point tray application 2.10
or later.
You can download Mouse Point from the Support >
Downloads page of the Amulet Hotkey website,
www.amulethotkey.com.
8. 2 Local manual updates (USB)
This section describes how to update the K4u
+
firmware directly
from the desktop on the source computer.
1 Save the .pkg file containing the firmware update to a
convenient location. This can be a folder on the source
computer or a network share.
2 On the source computer, right-click the Mouse Point icon in
the taskbar notification area (Windows 7) or system tray
(Windows XP).
3 (Optional) Click Read Switch Status via USB. The resulting
Status dialog shows the firmware version currently on
the K4u
+
.
4 Click Update Switch Firmware and FPGA via USB.
