8.0 RADIO FIRMWARE UPGRADES

From time to time, Microwave Data Systems releases new firmware for its 
radio products. This file can be installed in existing radios to take advantage 
of engineering improvements or additional features.

8.1 Obtaining new firmware

The latest firmware for each radio type may be obtained free from our Web 
site at:

www.microwavedata.com/service/technical/support/downloads/

Firmware is also available on disks from MDS that are bundled with a 
installation utility (MDS Radio Software Upgrade (upgrade.exe)) for 
transferring the firmware file on the disk to the radio.

Saving a Web-site firmware file to your PC

MDS firmware upgrades are distributed as a plain-text (ASCII) file with a 
“.S28” extension. Browse to find the desired “.S28” file for your radio on the 
MDS Web site. After finding your selection, use the right mouse button to 
select a path on your computer on which to save the file. (If this isn’t done, 
your browser may display the firmware file contents as text on the screen 
instead of downloading it to your local hard drive.) 

After the “.S28” file has been saved to your computer, you may use either 
MDS TransNET Configuration Software or MDS Radio Software Upgrade 
programs to install this firmware in your radios.

8.2 Installing firmware in your radio

1. Connect the PC to the radio’s 

DIAG

 port using an RJ-11 to DB-9 Adapter 

Cable (MDS Part No. 03-3246A01). If desired, a cable can be fabricated 
from the information shown in 

Figure 20 on Page 54

. 

2. Start the MDS TransNET Configuration Software. Open diagnostics port 

to the radio. The program will automatically read the radio’s profile.

3. From the 

File

 menu select 

Radio Firmware Upgrade

 and follow the prompts 

to install the new firmware into the radio. Do not press the 

Cancel

 button 

once the installation has started or it will leave the radio without any 
code. When the installation is complete, another radio may be connected 
to your PC and programmed.

NOTE: 

If a firmware installation fails, the radio is left unprogrammed and inoperative. 

This is indicated by the PWR LED flashing slowly (1 second on/1 second off). 
This condition is only likely to occur if there is a power failure to the computer 
or radio during the installation process. The installation should be attempted 
again.
