5.4 Software Upgrade Procedure
The following section outlines the steps necessary to update the DAX transmitter with a
different version of software than currently installed. As with the VT100 programming,
a PC and serial cable with DB-9 connector is required. The PC should have the Harris
Broadcast software update install CD inserted.
IMPORTANT NOTE:
The software update will automatically reset the transmitter during the procedure.
This will momentarily take the transmitter off the air. Therefore it is
recommended to perform this update with the transmitter OFF.
It is recommended to compare the current software revision with that about to be
installed to verify the version you are installing is not already loaded.
STEP 1 Verify software revision via the GUI:
•Pressing the INFO button takes you to submenu screen
•Select STATUS SUBMENU using the UP or DOWN buttons
•Press ENTER to bring up below screen
