OVERVIEW
In FW versions 1.3.x and above it is possible to upgrade the active firmware running on the module via the serial
interface. The Windows OEM Configuration Utility v5.07 and above can perform this operation for modules with
access to a PC, but for embedded applications it may be necessary for the OEM to program the FW upgrade through
a microcontroller. Upgrade of the FW over the air is not supported on the LT2510. The firmware upgrade procedure
will not affect the radio EEPROM settings except to update the version number.
UPGRADING VIA WINDOWS OEM CONFIGURATION UTILITY
Upgrading through the OEM Configuration Utility is a straight-forward process. The PC Settings tab has an option
when the LT2510 is the selected product to perform a Radio Firmware Update. This section of the OEM software can
be used to upgrade the FW of the radio connected to Port 1 of the software.
To perform a firmware upgrade:
1. Connect the Development Kit or other interface board with the LT2510 to the PC.
2. Select the Find Ports button, then select the appropriate Windows Comm Port from the drop down
3. Set the correct settings for the radio in Port 1. By default this is 115,200-8-N-1 with Hardware
4. Verify that the Port Status in Port 1 is “Open”
5. In the Radio Firmware Upgrade box, select Write File to Flash
6. In the Open File Window that appears select the appropriate LT2510 FW binary.
7. When the download is successful, a Success window will appear.
8. To have the radio begin using the new FW, select the Enable New Image button, this will reset the
