Instructions

1. Download and install the flash utility Flip from the Atmel Web site.
2. Unzip the file received from Virtual Cash Corp.
3. Make sure the VCA is unplugged and connect the serial cable between the DB9, located on top of the main circuit board, and your computer. If you received a serial cable from Virtual Cash Corp, plug that onto J11, the 3-pin header to the left of the battery, and plug the other end into your computer. If you're using a cable from Virtual Cash, you must still disconnect any harnessing plugged into the DB9.
4. Move jumpers JP1 (just to the left of the microprocessor) and J9 (just to the left of the battery) to positions 1 & 2.
5. Plug in the VCA.
6. Launch the flash utility.
   A) Go to Device > Select or press F2 and choose T89C51RC2.
   B) Go to File > Load Hex and retrieve the hex file you unzipped.
   C) 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 cannot, 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, you must select which operations to perform under the Operations Flow box found on the left side of the screen. Select 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 need 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. Remove power from the VCA and move jumpers JP1 and J9 to positions 2 & 3. Reconnect the harnessing to the DB9.
11. Test
