Loading the Update Programs/Data to the
Flash ROM
If you want to update the current programs/data stored in the flash ROM on the main PCB or after
you replace the main PCB, load the update programs/data to the flash ROM.
Writing requires a PC/AT-compatible computer running Windows 98/98SE, Windows Me,
Windows 2000 Professional, or Windows XP Home/Professional.
CAUTION:
During loading, do not turn the power off, interrupt loading operation, or load invalid
data. If you do so, loading will fail, causing the PCB to be unusable. You will need to replace the
main PCB and load update programs/data to a new PCB.
Preparation
You need to have the BHL2-Maintenance Printer driver and FILEDG32.exe (provided by Brother
Industries) on hand. Save them in an arbitrary folder in your PC.
Installing the BHL2-Maintenance Printer driver
To identify terminals connected via USB interface, a PC requires the corresponding virtual USB
devices to be implemented by driver/software. If you connect any number of machines to your PC,
therefore, the same number of virtual USB devices will be automatically configured on your PC. To
prevent virtual USB devices from being configured limitlessly, use the unique driver installation
procedure described below that enables your PC to identify terminals via a single virtual USB device.
NOTE:
Once this installation procedure is carried out for a PC, no more driver/software installation
will be required for that PC to identify machines. If the BHL2-Maintenance Printer driver has been
already installed to your PC according to this procedure, skip this section.
NOTE:
Before proceeding to the procedure given below, make sure that the BHL2-Maintenance
Printer driver (listed in
) is stored in your PC.
(1) Make sure that the power cord of the machine is unplugged from the electrical outlet.
If the machine is connected to a PC, unplug the USB cable.
(2) Switch on your PC.
(3) Plug the power cord of the machine into an electrical outlet.
(4) Enter the maintenance mode. (Refer to
)
(5) Connect the machine to your PC using a USB cable.
