D4T/D4R
Firmware Updates
As new versions of the firmware become available,
updates are accomplished with a software utility and
simple procedure. In many cases, updates must be
made to both transmitter and receiver to ensure com-
patibility and provide the latest feature set.
The software interface operates with Windows 2000,
XP and Vista operating systems.
Configuring the USB Port
1) Remove any previous LecNet2 installation from
your computer.
2) Install LecNet2 software. Use the CD supplied with
the D4 system or download the LecNet2 Software
Installer or the CD contents from the web site:
http://www.lectrosonics.com/lecnet2/lecnet2.htm
3) On the same web page, scroll down to LecNet2
Firmware Updates. Download the latest D4R and
D4T firmware files and store them in a convenient
directory on your local hard drive. The files are
stored on the web site as .zip files. After they are
extracted the filename extension is .rpd.
4) Connect power to the D4 unit.
5) Plug the USB cable into the D4 unit. If this is the
first time this unit has been connected to this com-
puter, Windows will ask for a driver location. The
default directory used by the LecNet2 installer is:
c:\Program Files\Lectrosonics\drivers
Once the driver is located, Windows will complete
the installation and display a message stating that
the USB device is now ready to be used.
NOTE: If a message appears during installation
stating that the driver is not signed by Microsoft,
click on Continue to finish the installation.
Installing Firmware
Make certain that the USB port is configured to com-
municate with the D4 unit. If not, follow the procedure
outlined above to install the USB driver.
Launch the D4 utility:
Start>All Programs>LecNet2>Tools>D4 Update Utility
16
The Browse button is used to select the file to be
loaded into the D4 unit.
The Write button initiates the installation process.
The Verify button on the D4 Utility program control
panel is used to compare the version of the selected
file with that of the firmware installed in the D4 unit.
Clicking the button will start the process. After a few
seconds, an OK screen will appear if the versions are
the same, or a mismatch screen will appear if the ver-
sions are different.
NOTE: Verification takes place automatically
during the installation process launched by
clicking the Write button.
The firmware version in the D4 unit is displayed briefly
on the LCD during the turn-on cycle. The version of the
downloaded firmware file is indicated by its filename.
1) Click on the Browse button and select the folder
where the downloaded firmware files are stored.
Select the correct file for either the receiver or
transmitter, whichever is connected.
2) Click the Write button to copy the new firmware
into the D4 unit. The progress bar will indicate as
the firmware is being updated.
3) After about 30 seconds an OK message will ap-
pear if the installation was successful.
4) Click the Exit button to close the software panel.
If the wrong firmware is installed into a D4 unit (such
as the D4R receiver firmware being loaded into the
D4T transmitter) the installation process will appear
to work but the LCD on the D4 unit will likely be blank
and the unit will not operate. Installing the correct firm-
ware will restore the unit to normal operation.
Compatibility with Quadra
Firmware v3.0 and higher enables compatibility with
the Quadra wireless IEM system, with lower latency
than earlier firmware versions. The D4T and D4R
must both be updated to v3.0 for compatibility with the
Quadra system.
M4T and M4R firmware v.3.0 is not compatible with
earlier firmware versions.
