manufacturer (Diamond Traffic Products). The Phoenix II has flash upgradeable firmware and can be uploaded through

the serial or USB ports via a PC computer either through direct connection or remotely via telemetry).

Some firmware is made custom to certain customers that request different unit operation of defaults. These are denoted

at the letter at the end of the firmware version (ex: 3.01w “w” = special settings for Washington DOT). If upgrading or

replacing EEPROMS, be sure to order and request these special letter EEPROMS if you use any other than the default

“a” firmware.

NOTE: Firmware updating of the main and sensor boards done through the serial or USB port needs to be

performed with a reliable connection and cannot be interrupted or stopped. It is highly recommend that a

direct serial connection be made for firmware updates as failure to complete the procedure will require the

unit to be sent back to the factory for programming. Upgrading should only be performed if absolutely

necessary and doing so by telemetry is done at the user’s risk. Please Contact Diamond Traffic Products for

specific requirements and any additional steps to complete a successful firmware upgrade.
