Memory Reset
To reset memory enter the AUTO “Auto Test” menu and scroll to the option to reset the memory. Press select
button 1 to select this option and follow the displayed prompts. Once the machine has cleared its memory it will
be ready to program.
EPROM REPLACEMENT
Software changes / upgrades are accomplished by changing the EPROM on the Control Board.
SBC (Single Board Controller) Software Update Procedure
This document describes how to update software on the Single Board Controller (SBC). Note: All existing
software revisions, except software version 804,920,870.01, will automatically update the software revision 804,
920,870.01 or higher upon installation. For SBC boards using 804, 920,870.01 software menu programming is
required to manually update the software.
Important: EPROM’s containing software is sensitive to Electrostatic Discharge (ESD). Failure to handle the
EPROM carefully could cause damage, which may result in a failed Single Board Controller (SBC).
ALWAYS KEEP THE EPROM IN THE ESD TUBE. GROUND YOURSELF ON THE VENDER CABINET
BEFORE REMOVING THE EPROM FROM THE ESD TUBE OR CONTROL BOARD. AN EPROM CAN BE
USED TO PROGRAM MANY VENDERS, AS LONG AS CARE IS TAKEN NOT TO DAMMAGE THE EPROMS
LEGS.
ALWAYS TURN POWER OFF BEFORE REMOVING OR INSTALLING EPROMS IN THE CONTROL BOARD.
Note : Use the SBC programming manual to program a vender that has a Single Board Controller (SBC) installed.
I. EPROM removal
•
Power down the Vender. Ground yourself on the vender cabinet before removing the
EPROM from the ESD tube or control board.
•
If the EPROM is present in the SBC, remove the existing EPROM from the SBC.
•
Note: An EPROM does not need to be in the board after the SBC has been programmed.
The EPROM can be used to reprogram other boards.
•
Verify the pins of the new EPROM are not bent before installing in the EPROM socket.
•
Install the new EPROM in the EPROM socket. Ensure the EPROM is oriented correctly with its
reference marker (locator) in the same direction as the reference marker (locator) of the EPROM
socket. Do not rely on the EPROM label for orientating the EPROM. See Figure 1.
II. Automatic Reprogramming (all 804, 920,870.01 software revisions)
•
Turn power on to Vender. When auto-updating, the display will remain blank while the red LED
on the board blinks rapidly for 3-4 seconds. Verify the new software version is shown on the
display. If the new software version (the software version of the newly installed EPROM)
displays, the SBC software has been successfully updated. If not, verify the EPROM is seated
properly, with the reference marker oriented correctly and follow instructions for manual update if
updating from 804, 920,870.01. If problems still exist, contact the Dixie-Narco Technical Service
Department.
Note:
To remove the EPROM after programming is complete turn power off, ground yourself
on the vender cabinet before removing the EPROM , remove the EPROM, turn power on, test
vender for proper operation.
III. Manual Reprogramming (all 804, 920,870.01 or if an EPROM does not automatically reprogram the SBC)
•
At power up, the current software version will be displayed. To manually program the control
board with the new software, press the blue service switch on the SBC to enter the service menu.
Advance to the “Auto Test” menu by holding buttons 1& 2 simultaneously. Enter Auto Test by
pressing button 1, and advance to the “Reprogramming Microprocessor” submenu by holding
buttons 1& 2 simultaneously.
