USB Update Procedure
1. First, un-plug any communication cables from the holding bin. These devices will interfere with the timer bar boot loading process.
2. Place the update files on the USB flash drive in the main directory (Do not put them in a folder on the flash drive). There are five files that you will need to put
on the drive. Two for the controller board, mainbin.hex and DHBFWBIN.TXT. Three for the timer bars, mainbar.hex, auxbar.hex and DHBFWBAR.TXT.
3. Once all files are on USB drive, turn power off to bin and place the USB drive with the files into USB port on the front of the bin.
4. While holding down crown button on front right side of the bin, above the power switch, turn the power to the bin on.
5. Keeping the crown button pressed, wait for the “BL” (boot load) message to appear on the screen. Release the button approx. 5 seconds after the “BL” message
appears or once the USB stick light begins to flash.
6. Wait for the display to show:
a. (blank while upgrading main bin firmware) e. BL02 (2 timer bars left to upgrade)
b. BL00 (searching for timer bars to upgrade) f. BL01 (1 timer bar left to upgrade)
c. BL04 (4 timer bars left to upgrade) g. BL00 (0 timer bars left to upgrade)
d. BL03 (3 timer bars left to upgrade) h. BN04 (4 timer bars detected and done with programming)
7. You can check the version number on the timer bars by pressing the Prince Castle logo button and the down button on timer bar.
*EHB34XX requires seven files. The two additional to those listed are mainbar2.hex and auxbar2.hex
