1INTRODUCTION
1.1 Outline
Should it happen that the boot loader becomes corrupted on a WR31 product, it is possible for an end
user to re-load the boot loader by following this guide.
The symptoms of a corrupted boot loader are usually as follows. When applying the power, the only
LED to illuminates is the power LED. It is also possible that other “unusual” LED patterns may occur
depending upon how “damaged”the boot loader is.
1.2 Assumptions
This guide has been written for use by technically competent personnel with a good understanding of
the communications technologies used in the product and of the requirements for their specific
application.
This quick note applies only to:

2PHYSICAL CONFIGURATION
2.1 Equipment Required
A PC running a Microsoft WindowsTM based operating system.
1. A PC connected to the Internet running a Microsoft WindowsTM operating system with a built
in serial comm. port. (USB to serial adaptors do not work well.)
2. A 9-way “straight through” serial cable to connect the PC directly to the WR31.
3. A “USB A to USB A” cable to connect the PC directly to the WR31. (No mistake, A to A)
4. An Ethernet switch/hub to connect the PC to the WR31 (usually your normal office Ethernet
switch/hub will be fine if there is a spare port)
5. CAT 5 cables to connect the WR31 and PC to the Ethernet switch.

2.1.1 Diagram
The following diagram represents how the equipment will be connected during the repair process:
The internet connection is not essential but may be useful during troubleshooting. It is essential that
the PC’s Ethernet communication interface is configured correctly (e.g. it has an IP address)
Also note that the Ethernet switch/hub used must have spanning tree protocol disabled.

3STEP BY STEP INSTRUCTIONS
3.1 Install FlashWriter
Install the latest version of FlashWriter from the following link:
http://ftp1.digi.com/support/firmware/FlashWriter.msi
3.2 Download the .ALL file:
Download the following zip file to your PC and extract all the contents to a single folder
http://ftp1.digi.com/support/firmware/transport/flashwriter/latest/wr31-flashwriter-x.x.x.x.zip
Click: http://ftp1.digi.com/support/firmware/transport/flashwriter/latest/
where X.X.X.X is the current firmware version.
Open the .ini file extracted and add the following text to the second line (be sure to include
the comma at the end).

3.3 Make the initial connections
1. Connect the “straight-through” serial cable between the PC and the “Serial 0” on the WR31.
2. Connect the WR31’s Ethernet (LAN 0) port to your “office network”.
3. Ensure the PC is also connected to the same “office network”
4. Connect one end of the “USB A to USB A”lead to your PC. Do NOT connect to the other end to
the WR31 yet.

3.4 Launch FlashWriter
Launch Flashwriter from the start menu. Select the communications port number (PC comm. port
number) to which the WR31 is connected. (On most PC’s with a built in serial port, this will be “1” OR
“2”. Leave the other settings at their default values (TFTP and Event driven mode ONLY ticked):
Click Load
If your PC has more than one network adapter, be sure to select the one that represents the
connection to “Office Network” illustrated in 0.
If your PC only has a single network adapter this screen will not appear:
