Appendix B: Installing New Firmware

From time to time, updates are made to WebRelay-Quad™ firmware. The firmware can be

updated in the field. The procedure for updating the firmware is outlined below. Please note that it

is important that this procedure is followed precisely.

Requirements

The firmware update software requires Windows XP/Vista/7 with the .Net framework installed.

The .Net framework is generally installed automatically through Windows update. To install it

manually, go to the following address:

http://www.microsoft.com/downloads/details.aspx?FamilyId=333325FD-AE52-4E35-B531-

Select the Download button. Once you've downloaded the installation file, double click on the

installation file to install the framework.

Setup

1. Download the firmware zip file from the ControlByWeb website. Only a WebRelay-Quad™ image

can be installed on a WebRelay-Quad™ so make sure the correct image is being downloaded.

2. bootloader.exe will connect to WebRelay-Quad™ using default IP address 192.168.1.2, not the

address currently assigned to WebRelay-Quad™. After the update, all settings will be lost and the

device will return to its default IP address of 192.168.1.2.

Configure the PC to the same subnet as the IP address 192.168.1.2, such as 192.168.1.10. For

instructions on doing this, see section 2.3 Establishing Communications for Setup.

Note: The IP address of the WebRelay-Quad™ will automatically be set to the default 192.168.1.2

during the update process.

Note: A crossover cable cannot be used during the update procedure; an ethernet switch will be

necessary to properly update the firmware.

3. Open the bootloader.exe utility on the computer by double clicking on the downloaded file (Figure

Appendix B.1).

4. Within the ControlByWeb™ Programmer utility programmer, select File, then Open. Specify the

firmware image downloaded from the ControlByWeb™ web site.
