3.2 Downloading and Transferring
This section explains how to download application programs from a PC into the ADAM-4500 flash ROM
and how to transfer files from a PC into ADAM-4500's SRAM.
Install Utility Software on Host PC
A utility disk containing the following files and directories is included with each ADAM-4500.
. ALLFILE
<DIR>
. LIBRARY
<DIR>
. EXAMPLE
<DIR>
. ADAMMINI.HEX
. ADAM_DEM.HEX
. ROM-DOS.HEX
. DEMO-DIS.HEX
. ADAMMINI.BAT
. ADAM4500.EXE
. HEXCAT.EXE
. ROMDISK.EXE
Copy all the files and directories on the utility disk to the host computer hard drive.
