Upgrading the Flash ROM Firmware
The MetroSet2 program is a functional component of Metrologic’s new line of
Flash- based scanners. This program allows the user of a Metrologic 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 MetroSet2 program, and blasts off to new software
upgrades.
Each MS5145, 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), IBM 468X/469X (-11), low speed
HID/POS USB (-38), and integrated full speed USB (-40) units can be upgraded.
To upgrade all units, a power supply and PowerLink cable (MLPN 54-54012) are
required. For RS232 units the 54-54000-3 cable will work.
The upgrades and custom software versions will be supplied by Metrologic 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 a Metrologic service
representative for additional assistance.
MetroSet2 incorporates all functions that were previously in Meteor.
* In some custom units the standard green LED has been replaced with a blue LED and
the red LED has been replaced with a white LED.
