4.7 Upgrading The Flash ROM Firmware
The Meteor program is a functional component of Extronics new line of Flash-
based scanners. This program allows the user of Extronics scanner to quickly
upgrade to a new or custom version of software. It requires the use of a personal
computer running under Windows 95 or greater and the use of a communication
port. The user merely connects the scanner to a communications port of the PC,
launches the Meteor program, and blasts off to new software upgrades.
Each MS9500, regardless of the version number or communication protocol, can
be upgraded. In other words, all RS232 (-41), keyboard wedge (-47), light pen (-
41), laser emulation (-00), OCIA (-9) and IBM 468X/469X (-11) units can be
upgraded. To upgrade all units, a power supply and PowerLink cable
(MLPN
54-
54012) are required.
The upgrades and custom software versions will be supplied by Extronics in files
called Motorola S-record files. These files contain all the information needed to
upgrade the scanner. Simply add this file to the working directory or retrieve from
its current location.
The program guides the user with its simplistic one click approach. The user must
first select the file; once selected and verified, the file is ready to be used in the
upgrade. Press the button to upgrade the scanner, the unit will go into a "flash
mode" — both the green and red LEDs will be on. The user can follow the progress
of the upgrade by watching the screen for details. When the upgrade is complete,
the scanner will respond with its normal one beep on power up. If two beeps occur,
the scanner did not upgrade properly. (Contact an Extronics for additional details).
