Firmware Upgrade
Ensure that any customised parameters are saved before any firmware upgrade is
undertaken. Firmware upgrades are performed in ‘Bootloader’ mode. Note that
all flow measurement and output operation will be halted when the sensor is in the
‘Bootloader’. Please follow these steps:
1. Please ensure that the sensor is connected to a PC via the RS485 port. Prior
to reprogramming, you will need the firmware file, and the COM port
number of the RS485 connector.
2. Establish a connection to the sensor, and it is advisable to save any
customised parameters before beginning an upgrade.
3. You will require Service access to switch the device into Bootloader mode,
and to activate Bootloader control.
4. First place the device into bootloader mode by selecting System > Switch
Device into Bootloader.
5. Select System > Bootloader control, which will launch the Bootloader
interface. As seen in Fig.9.
6.
Once connected click ‘Load Hex file’, and choose the firmware file you are
using to upgrade the sensor.
7.
Click ‘Erase-Program-Verify’ and await for the process to finish.
8. When the ‘Verification Successful’ message is displayed, click ‘Run
firmware’ and the Bootloader Interface will close down.
9. Select the ‘connect’ button on the software, and the sensor will reconnect to
MicroFlow PC with the new firmware installed.
