                    +++++++++++++++++++++++++++++


This document contains information about how to update your modems with
boot code and modem code preparing them for future updating via the manager 
software.


Step One -- Unzipping file

After copying MRUPDATE.EXE to your hard disk into a subdirectory type
"MRUPDATE".  The self extracting file should expand and create 11 files
besides the original file.


Step Two -- Boot Code Version

Determine the version of the boot code for each modem to be updated.  This
can be done by sending the command AT*FI to each modem through the online
window in the management software or on the rs-232.  If your boot code version
is NOT up to the latest version, you need to first update the boot code and
modem code via the rs-232. After updating to the latest boot code and modem
code, future updates can be done with the Management Software.  Here is a list
of MR modems and there latest boot code.

MT2834MR 		20.00
MT1432MR-rev.F or G	21.00
MT2834MR-ROM	30.02	All MR-ROM modems were shipped with 30.02
MT2834MR6		27.27 	All mr6 modems were shipped with 27.27

Note: If your modem has the current boot code, go to Future Updates.


Step Three -- Boot code Update

The boot code can be updated using FLASHPRO and the file 28MRBOOT.HEX for
28.8k (MT2834MR) modems or 14MRBOOT.HEX for 14.4k modems(for 14.4k modems run
FLASHPRO -m) also found in the installation directory. For information on how to use
FLASHPRO please refer to Flashpro.txt at the end of this document.  After 
updating the boot code the modem's CD, 24K (14.4K) and 19.2K (96K) lights
will blink and the TEST light will be on solid. If this does not happen please
contact technical support. At this point you MUST update the modem firmware
to 1.10c or greater for 28.8k modems or 2.11 or greater for 14.4k modems.

Step Four -- Modem Firmware Version

Determine the version of the modem firmware by sending the command ATI1
through the online window or highlight a modem and select from the menu bar
FIRMWARE - VERSION - MODEM. If you have just updated boot code this will have
to be done anyway.  If the firmware is NOT 1.10c or greater for 28.8k modems
or 2.11 or greater for 14.4k modems , you will need to update the modems.
This may be done using FLASHPRO (this will be the last time you will need
to use FLASHPRO to update modems) and a .hex file.  For information on how
to use FLASHPRO please refer to Flashpro.txt at the end of this document.
Each modem takes approximately 3 to 4 minutes to update boot code and modem
FIRMWARE. The modems may remain in the rack busied out before beginning
FLASHPRO. This is the list of the modems current firmware.  

MT2834MR                28MR114.HEX
MT1432MR-rev.F or G	14MR211B.HEX
MT2834MR-ROM            28MR314E.HEX
MT2834MR6               28MR604C.HEX

DO NOT flash the incorrect firmware into your modem, because it will corrupt 
the boot code chip and need to be sent in for repair.

Future Updates

The next time you need to update modem firmware, you will be able to use
the MMM software instead of other methods such as FLASHPRO. Updating with
the MMM software will allow for multiple controllers or modems to be updated
at one time.  Once the software is running, highlight the modems or racks you wish to 
update, then tag firmware - update - modem / controller and update devices.  
Note: 


                             FLASHPRO.TXT
                             ++++++++++++
This document will explain how to use FLASHPRO to flash any of our flash
upgradeable modems.

FLASHPRO.EXE is the utility for upgrading the firmware in your modem.
SETCOLOR.EXE can be used to change the screen colors for flashpro.  
  
Go into a communication program or an online window and give your modem  
this command AT&W1Z, exit the program. This is VERY IMPORTANT your modem
may lock if you do not do this and you will have to send it in to upgrade it.  
  
At the prompt type flashpro, this will bring up the flashpro program.

****RUN FLASHPRO -m (lower case m) to program ONLY 14MRBOOT.HEX, otherwise 
run FLASHPRO to program the modem**** 

You should now see a menu with 3 options, Configure, Select File to Program,
and Program Firmware. 

Select the Configure option.  A dialog box will appear for you to select
the communication port type, baud rate, device type, and other settings.  
After selecting the settings you need, hit <ESC>. This will return you to
the beginning menu.

Next select the Select File to Program option.  A dialog box will appear
for you to select an available .hex file to program into your modem.  
Four files should appear; two for 28.8k modems -- 28mrboot.hex (boot code)
and 28MR111.hex (modem firmware) and two for 14.4k modems -- 14mrboot.hex 
(boot code) and 14MR211B.hex.  All of these files except the modem firmware
were included with MMM 4.2.  After selecting the correct .hex file continue
to the next step.

The final step is to select the Program Firmware option.  This option will
program the selected .hex file into your Multi-Tech Systems modem.  The  
software will now begin to flash the modem.  Now the software will take
care of the rest.
  
After it has been executed you should go back into the communication
package and give the modem the same command, AT&W1Z. Also, ID the modem
with the command ATI1I2 this should list out the revision of firmware
and the modems model number.
