Spectrum24 RF Terminal Setup
Updating System Software on Flash Disk
Updating the LWP hex image means loading the new system files on the flash disk using the
SENDHEX utility on a PC. It is possible to perform this update on multiple terminals in a
cradle at one time, with each terminal running Program Loader from Command Mode.
Note: The 6840 is shipped with the LWP hex file installed. Use this
procedure ONLY:
• to load a new version of LWP greater than 3.03
• if you experience serious difficulties
• if you are so directed by Symbol’s Technical Support staff.
Option: Using _L.BAT to Update System Software
If the 6840 terminal contains a LWP hex file of version 3.03, you can follow the instructions
for installing application software on the flash disk using _L.BAT through step 6, when the
terminal is reinitialized. Proceed to step 6 of this procedure at that point.
Note: Be sure, when entering the SENDHEX command on the PC, to issue
the command from the directory where the hex file (LWP.HEX) is
stored.
Initiate Host Communications on the PC
To update the system software:
1. Power on the host computer.
2. On the PC, change to the directory where the system hex file (LWP.HEX) is stored
and type the following command at a DOS prompt:
SENDHEX LWP 384 [1|2] <ENTER>
