The MS9590 and the MS9591 are part of Honeywell's line of scanners with flash
upgradeable firmware. The upgrade process requires a new firmware file
supplied to the customer by a customer service representative and MetroSet2
. A personal computer running Windows 95 or greater with an
available RS232 serial or USB port is also required to complete the upgrade.
PowerLink Cable #54-54014 is required when using RS232 for the
upgrade process. This cable can be ordered from Honeywell. Do not
use the standard cable supplied with keyboard wedge or RS485
scanner interface kits. If using USB for the upgrade process, the
standard USB Type A cable provided with the scanner can be used.
Do not disconnect the cable or turn off power to the scanner during the
flash upgrade process. Failure to comply with this warning will cause
a critical scanner failure.
