Field Removal / Replacement of
ControlWave-series BOOT FLASH ICs
Damage to the BOOT FLASH IC or CPU Board because of failure to follow the
instructions provided herein will result in termination of warranty.
• Wear a properly connected ESD Wrist Strap.
• Make sure the ESD Work Mat is properly connected.
• Place the Printed Circuit Board on an ESD Work Mat.
• Make sure that the proper BOOT FLASH IC has been provided for the CPU
Removal of the BOOT FLASH IC results in a loss of flash configuration data and
archive files. Flash configuration must be saved to an FCP file on a PC, and archive
data must be collected /exported to disk files prior to chip removal. A summary of
these procedures is included below; see the Open BSI manuals for more detail.
DO NOT Remove/Replace PROM without practicing ESD Protection!

Part 1 – Preserving Your Data – Save Configuration Parameters to FCP File
1. Connect a PC, equipped with Open BSI, to serial COM port 2 of the ControlWave unit.
2. Click on Start Æ Programs Æ OpenBSI Tools Æ LocalView.
3 If you have a pre-defined Configure Mode view mode (*.LVG) file, use it to connect, and
skip to Item 6, otherwise choose ‘Configure’ for the “Mode”, enter ‘myfile’ in the “Name”
field, and click on the [Create] button.
4. From the Communication Setup page, choose the PC COM port you are using, and the baud
rate, and click on [Next].
5. From the IP RTU Setup page, choose the local address of the ControlWave, and specify the
type of ControlWave unit you are connecting to, then click on [Finish].
6. The Flash Configuration Utility will appear. Click on the [Load From RTU] button. The
unit’s configuration parameters will be read into the Flash Configuration Utility.
7. Click on [Write Profile To File], choose the folder where you want to save your
configuration data, specify ‘myconfig’ in the “File name” field, then click on [Save]. The
configuration data will be saved in an FCP file on the PC. Leave the Flash Configuration
Utility and LocalView running.

Part 2 – Saving Array Files to Disk (Only required if you need to save this data)
1. With LocalView running, click on Start Æ Programs Æ OpenBSI Tools Æ Common
Tools Æ Data Array Utility.
2. If you have a pre-defined array script, use it, otherwise specify the number of the first array
you want to save in the “Array” field, choose the appropriate “Array Type”, and specify a
path and filename to hold the array data in the “File” field, then click on [Save to Disk].
Repeat this step for each additional array you want to save. Leave the Data Array Utility
running.
Part 3 – Collect Archive Files
Archive Files are automatically deleted once the chip is removed, therefore, if you want to save
this data, you should collect those files using the Open BSI Harvester. See the Open BSI
Harvester Manual for details. NOTE: Archive files cannot be re-imported, just exported.
Part 4 – Removing the Chip
(Refer to Figure 1)
1. Wear an Electro-static Discharge
(ESD) Wrist Strap that is properly
connected to an ESD Work Mat,
which in turn, is properly grounded.
2. Turn OFF power to the
ControlWave.
3. Place the CPU Board assembly onto
an ESD Work Mat.
4. Grasp the Chip Carrier Extraction
Tool as shown in Figure 1.
5. Removing the BOOT FLASH IC
requires care. To remove the BOOT
FLASH IC properly, the Chip
Carrier Extraction Tool must be
alternately switched between the IC
Socket’s FLASH Device Extraction
Slots until the BOOT FLASH IC can
be gently removed. To begin
removing the BOOT FLASH IC,
insert the Chip Carrier Extraction
Tool’s Extraction Tip into one of the
IC Socket Extraction Slots in the
BOOT FLASH IC’s Socket. You
should not attempt to pry out the
BOOT FLASH IC forcibly or in
one step.
Pry downward on the IC Socket just enough to feel the BOOT FLASH IC nudge. Now insert
the tool’s Extraction Tip into the other IC Extraction Slot, and again in an effort to gently
remove the BOOT FLASH IC, pry downward on the IC Socket just enough to feel the BOOT
FLASH IC nudge. Go back and forth in this manner (about four times) until the BOOT
FLASH IC can be removed by hand.
