Flowire Software Upgrade Procedure

‎

Flowire

This article describes how to upgrade the software in Flowire devices.

There are different ways, depending on how old the current software is:

• If the current software is 4.x, the upgrade can be done from the web page of the Flowire unit, or by using the VS-IMT tool
• * If the current software is 1.x or 2.x, the upgrade must be done via the serial interface of the Flowire unit

How to determine the current software version

• Hardware version 0105 (Item: 1008080110.0105) and newer has version 4.x installed from factory, and can be upgraded via the web interface or via the VS-IMT tool.
• Hardware version 0104 (Item: 1008080110.0104) and older has version 1.x or 2.x installed from factory, and must be updated via the serial interface.

You can also check the Flowire unit from you PC: If you can ping the device, but not access it via the web browser, it is an old software version and it must be upgraded via the serial interface.

Upgrading from software version 4.x

Upgrade via the Flowire Web Interface

Flowire units with software version 4.x can be upgraded through the web interface of the Flowire.

The Flowire units are automatically assigned an IP address from the network if there is a DHCP server present. You can then access the Flowire units web interface one by one and perform the upgrade.

If there is no DHCP server on the network, the Flowire units will by default have a static IP address 169.254.1.10. In this case there will be multiple Flowire units with the same IP address on the network, and you need to isolate the Flowire unit which is going to be upgraded from the others in the network.

Isolating the Flowire units one by one

Although it is not necessary for the Flowire to perform its function, it is good practice to change the static IP to something unique at the same time, for easier maintenance in the future.

Prerequisites

• TFTP Server: This upgrade method require that an TFTP Server is available. A TFTP Server program can be downloaded from http://tftpd32.jounin.net.
• Software package: The latest software package must be downloaded from the download site. Unzip the files to a folder.

Upgrading

• Start the TFTP server and Browse to the folder where the software files are stored.

TFTP server setup

Use a standard web browser and enter the IP address of the Flowire (e.g. 169.254.1.10) in the address field.

Flowire upgrade - enter TFTP server address

Enter the TFTP server IP address and select Upgrade.

Upgrade: Upgrades the software and keeps all custom settings
Full Upgrade: Upgrades the software and performs a reset to factory settings

As a precaution you should set the NMK again after update

Upgrade using VS-IMT

1) Requirements

• Windows PC
• DHCP server. (If there is no DHCP server in the network, a temporarily DHCP server can be set up using for example Tftpd32 or Tftpd64 by Ph. Jounin (http://tftpd32.jounin.net)
• Simple switch
• Ethernet cables
• Flowire unit(s)
• Flowire power supply

If there is a DHCP server already in the network, please skip to point 4.

2) PC setup Set static IP address 169.254.1.2 on your PC

3) DHCP server setup

• Start the Tftpd
• Click the settings button:

• Choose the DHCP tab and set these settings:

• Choose the Global tab and make sure TFTP Server and TFTP Client are disabled:
