Transferring files to SRAM (ADAM-4500's D-drive)
The ADAM-4500 provides 234 KB of free SRAM for use in program operation, and as working
memory space in the event you want to test your system control logic or simulate system
performance before downloading the execution code to the flash ROM. You can transfer files
from a host-PC to the ADAM-4500's SRAM (D drive). Execute the utility software, select terminal
mode, and press Alt-T. File transfer will begin and the screen shown in figure 3-4 will appear.
Figure 3-4: File Transferring
Key in the specific directory and file names you want to transfer. Press <enter> to complete the
file transfer. You can check the files in D drive.
We recommend that users test new applications on their host PC before installing them in the
ADAM-4500. However, the performance of the host PC may differ greatly from that of the ADAM-
4500. Therefore, users may find it desirable to install an application that has been tested on the
host PC into ADAM-4500's D drive for testing prior to burning it into the flash ROM. It takes less
time to alter and reinstall a program into the SRAM than into the flash ROM, so using the SRAM
during debugging on the ADAM-4500 may be more efficient.
3.3 Steps to Building a Successful Application
Step 1: Write and simulate control logic on a PC
Connect a host-PC to the I/O device network you want to control. Write the control logic for your
application on the host-PC and execute the application on the PC to verify that it works properly.
Step 2: Connect the cables
Replace the host-PC in the control network with the ADAM-4500 and reconnect the proper power
and communications cable in the network to the ADAM-4500. Connect the download cable
between the host-PC and the ADAM-4500.
