LAB599 FIRMWARE UPDATE UTILITY


FIRMWARE UPDATING:

1. Connect the TX-500 to a computer and run TX-500 Firmware Update Utility, which will 
load new firmware. Use the 4-pin Cat-serial connection cable that came with your radio.

2. While holding the third top function key, turn on the TX-500 by pressing
the POWER button. The screen will display “The loader is waiting…”.

3. Start the update application. Select the COM Port (read note below) and the downloaded
firmware file. Сlick “Update” on the utility. The update will begin and progress will display
in the update program and the TX-500 screen. Do not turn off the computer or transceiver
until the download is complete. After the software download is complete, turn off the
transceiver and turn it on again.

4. Check firmware version.


USB DRIVERS NOTES: 

The transceivers were supplied with different versions of USB adapters: 
1) on Prolific PL2303 chips (black case); 2) on FTDI FT232 chips (blue
case). If your OS does not automatically install the drivers, please download 
the latest drivers (lab599.com/downloads/) and install the drivers manually.

COM PORT SELECTION: 

Open Windows Device Manager and expand the "Ports (COM & LPT)" item. 
If you are using a serial port built into the computer, it will be listed 
as a "Communications Port". The USB to Serial Adapter will be listed as a 
"USB Serial Port”. The COM port number will be seen alongside each device.
