4.3 Firmware update
A firmware update can only be performed view a USB connection. Therefore the USB connection
setup (see 4.1) is required.
If the device is used in USB setup, the device can be connected to a PC via USB and the firmware
can be updated using the "pqUpgrade" tool.
If the device is used in RS232 setup, the device needs to be configured for USB setup first.
There are two ways to switch to USB connection setup:
1.
Using a command string (see 6.4) After the communication is set to a USB connection
setup, the device resets and starts in the selected communication setup.
2.
Press the measurement button of an unplugged device. Plug in the USB cable (USB set-up)
connected to the PC and wait 10s before release the measurement button. Then the update
tool "PqUpgrade" will find the device. "PqUpgrade" will start the device in USB virtual com
port setup. In order to return to the same communication setup as before the update a reset
is required.
