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, Vista and Windows 7 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 Quadra 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 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. There are separate files
for the receiver and the transmitter.
4) Install batteries or connect power to the unit.
5) Plug the USB cable into the unit. If this is the first
time this unit has been connected to this computer,
Windows will ask for a driver location. The default
directory used by the LecNet2 installer is:
c:\Program Files\Lectrosonics\LecNet2\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 the Firmware
Make certain that the USB port is configured to com
municate with the unit. If not, follow the procedure
outlined above to install the USB driver.
Launch the utility:
Start>All Programs>LecNet2>Tools>D4/M4 Update
Utility
Rio Rancho, NM
The Browse button is used to select the file to be
loaded into the unit.
The Write button initiates the installation process.
The Verify button on the Utility program control panel
is used to compare the version of the selected file with
that of the firmware installed in the 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 versions are
different.
NOTE: Verification takes place automatically
during the installation process launched by
clicking the Write button.
The firmware version in the 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 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 unit (such as
the M4R receiver firmware being loaded into the M4T
transmitter) the installation process will appear to work
but the LCD on the unit will likely be blank and the
unit will not operate. Installing the correct firmware will
restore the unit to normal operation.
The USB port is on the side panel of the receiver and
on the rear panel of the transmitter.
