MKIII SERVICE MANUAL 29
8 MAIN ELECTRONICS FIRMWARE / CONFIGURATION LOADING
PROCEDURES
This procedure is used to upload new firmware for the BREWER Electronics or to update the
configuration files stored in flash memory. The only time this procedure is required is if the firmware
has been corrupted due to electrical surges or the memory had been replaced or if the
configuration has changed due to some physical changes to the sensor settings or position stops.
8.1 INSTALLATION OF BREWCMD SOFTWARE
Before using any of the procedures in this section the Brewcmd.exe software must be installed and
properly configured.
Exit out of the BREWER operating program to DOS.
Take the supplied configuration disk and put it into the computer used to reconfigure the BREWER.
Copy the files from the floppy disk a:\bdata\nnn to the c:\bdata\nnn subdirectory using the
command
copy a:\bdata\nnn\*.* c:\bdata\nnn

Edit the file c:\bdata\nnn\brewcmd.ini. Ensure that the com port setting indicated matches the
comport setting for your Brewer.
8.2 RESTORE BACK TO COSMAC MODE
In certain circumstances where the signal line is placed in a permanent Break signal condition, the
BREWER will continually try to reset but eventually it has determined that there is a problem and it
will halt trying to reset and go into Loadmode. This fault can happen when the RS422 cable has
been incorrectly wired or has shorted together to simulate a break condition. To confirm that the
processor is actually in loadmode, remove the weather proof cover of the BREWER and look down
into the Main electronics board between the cover plate and the microprocessor board. You should
see a flashing LED light and if it is in loadmode, it will be flashing quickly in 1/4 second intervals.
The procedure to restore the system back to the Cosmac mode of operation is as follows:
Change to the directory c:\bdata\nnn by typing the command cd\bdata\nnn

Run the program Brewcmd.exe by typing brewcmd

This program is a utility to allow the user to
communicate to the BREWER Microprocessor and change operating modes or upload files.
If all the connections are correct, the display will reply that BREWER responded and at what baud
rate it is communicating. [Using load mode at 9600 baud, on com 1; tracing is
off]
It is expected that it will be in Loadmode but it could be in Opmode as well.
To return it to its normal operating mode, type cosmacmode

The instrument will reset itself by resetting all of its motors and the display will display the following
with other status information.
Motors Initializing.
When the instrument has completed resetting all of the motors, the display will now respond to low
level commands.
