Instructions

1. Download and install the flash utility Flip from the Atmel Web site.
2. Unzip the file received from Virtual Cash Corp.
3. Connect the serial cable between the DB9, located on top of the main circuit board of the VCA, and your computer.
4. Set the switch located next to the DB9 so that rocker is pointing towards the right (away from the VCA).
5. Plug in the VCA. It should not boot, but the display back lighting should be visible.
6. Launch the flash utility.
   • Go to Device > Select or press F2 and choose T89C51RC2.
   • Go to File > Load Hex and retrieve the hex file you unzipped.
   • Go to Settings> Communications > RS232 or press F3 and press the connect button.
   If the program is able to communicate with the microprocessor, all the controls on the program will enable. If it can’t, a timeout message will be displayed. If you get a timeout, use the checklist to figure out why the connection failed. We recommend a baud rate of 57.6K.
7. Before starting the download, use the Operations Flow box on the left side of the screen to select which operations to perform (Erase, Blank Check, Program and Verify).
8. Press Run in the lower left of the screen to start the flash download. The checkboxes should turn green after successful completion of each stage. If any of them turn red, a problem has occurred and you will have to start over.
9. If you have more than one machine to flash, press F3 after the download completes. This will break the serial connection.
10. Flip the toggle next to the DB9 to the run position (rocker towards the DB9). The VCA should boot up.
