DRB-25 Upgrader is an application designed to automate the process of upgrading 
software on DRB-25 Transceiver and Controller modules.  

Upgrader v3.09 includes non-IP Controller v3.10 and Transceiver v4.60

Non-IP Controller v3.10 adds a Carrier Operated Relay (COR) capability from the 
Multi-mode Interface Module with: 

    - GP3 OUT used for the radio in slot 1
    - GP4 OUT used for the radio in slot 2

Transceiver v4.60 adds:  

a.  the ability to program a transceiver with a default power up channel

b.  programmable squelch level for scan channels

Transceiver v4.60 must be used with programmer v2.5 where the default power up channel
is included under "Radio Wide Settings".


Installation

DRB-25 upgrader consists of the following two files:

1.	WWSPM02000_122.exe	 	Main executable file
2.	WWSPM02000_122.hlp		Application Help file

Ensure these files reside in the same directory on the PC.

Using the Upgrader

To use DRB-25 upgrader, follow the steps below.

1.   Connect the data cable between the front panel of the DMR 
     Transceiver module and the PC serial port.

2.   Run the application "WWSPM02000_120.exe" on the PC

3.   Select the Transceiver or Controller radio button in the DMR 
     upgrader dialog box according to the module you will be upgrading.

4.   Select the desired baud rate and com port.  The higher the 
     baud rate selected, the faster the upgrade will take place.  
     However higher speeds are more susceptible to transfer errors.  
     Try starting with the fastest speed and reducing if necessary.

5.   Click on the "GO!" button.  Upgrading will then commence.  All 
     DRB-25 upgrader dialogue controls are disabled during the upgrade 
     process.

6.   If a password is required a password dialogue box will pop up 
     and the user will be prompted to enter a password.  The default 
     password of "1234" is pre-entered into the dialogue box by default, 
     so if the default password is required simply click on "OK" or 
     press enter to continue.  If a different password is required 
     enter the password and press enter or click on OK.  If the 
     incorrect password in entered the user will endlessly be prompted 
     for one.

7.   A series of messages will flash on the screen below the upgrade 
     progress bar, and after a few seconds the progress bar will start 
     moving indicating that the application code is being transferred 
     to the module and that the upgrade is underway  Underneath the 
     progress bar the transfer progress in indicated numerically.

8.   After the progress bar indicates the transfer is complete, the 
     Upgrader will proceed to erase the module software and replace 
     it with the new software.  Do not attempt to remove any cabling, 
     reset the module or terminate the program at this point, as this 
     may lead to a critical failure in the upgrade process.

9.   After a few seconds the message "Rebooting Transceiver" will 
     appear under the progress bar.  A few seconds after this the module 
     should reboot, and a message will pop up onto the computer screen 
     indicating that the upload is complete.  At this point the serial 
     cable can be disconnected and moved onto the next module, or the 
     program can be exited.

Trouble Shooting

If an upgrade fails, a message will popup indicating that a failure occurred.  
Possible causes of a failure are:

1.   Incorrect com port setting, or another application on the PC is 
     using the com port – Verify that settings are correct and that no 
     other serial applications are running on the PC

2.   Cable plugged into the wrong module, or module not powered up – 
     Verify that module is powered up and that cable is plugged into 
     front panel data port.

3.   Problem with length of serial cable or excessive noise – Reduce 
     baud rate and try again.
