9.2 Firmware-Update for IDS Sensors
General information Available firmware updates for IDS sensors are provided on the Inter-
net. With the "Firmware Update" program and a PC you can update the
firmware of an IDS sensor to the newest version.
For updating, connect the IDS sensor to the Multi 3430, and the
Multi 3430 to a PC.
For the update via the USB-B interface, the following is required:
z a free USB interface (virtual COM port) on the PC
z the driver for the USB interface (on the enclosed CD-ROM)
z the USB cable (included in the scope of delivery of the Multi 3430).
Program installation
Program start
Firmware update
After switching the meter off and on you can check whether the sensor
has taken over the new software version (see page 103).
1 Install the downloaded firmware update on a PC.
An update folder is created in the Windows start menu.
If an update folder already exists for the sensor (or sensor
type), the new data are displayed there.
2 In the windows start menu, open the update folder and start the
firmware update program for the IDS sensor
3 Connect the IDS sensor to the meter.
Only the sensor connection in the lower section of the socket
field (channel 1) is suitable for firmware update.
4 Using the USB interface cable, connect the Multi 3430 to a
USB interface (virtual COM port) of the PC.
5 Switch on the Multi 3430.
6 In the firmware update program, start the update process with
OK.
7 Follow the instructions of the firmware update program.
During the programming process, a corresponding message
and a progress bar (in %) are displayed.
The programming process takes up to 5 minutes. A terminatory
message is displayed after a successful programming process.
The firmware update is completed.
8 Disconnect the Multi 3430 from the PC.
Meter and sensor are ready for operation again.
