UPGRADING FIRMWARE
Occasionally AMS releases new software which adds features or
functions that you might want to use to enhance your operation.
Additionally there may be times you want to convert a board from
chilled to non-chilled or to add Health & Safety operation. In
these cases you will have to install new firmware in your board.
The Epic operates with
P/N 3870
firmware for ambient
temperature machines.
To upgrade firmware, you must first obtain the new file from the
AMS website and store it in a micro SD card. Then follow the
steps below to transfer that new firmware into the Control Board’s
memory.
1. Open the Front Door and leave the machine turned
ON.
Please read the note on DEX data below.
2. Locate the socket for the micro SD Card (See
FIRMWARE UPDATES
to the left).
3. Insert the micro SD Card firmly into the socket (it
will only fit one way). Some models may latch it in
place.
4. Press the yellow Mode button. After a few seconds,
four software options will scroll on the display.
5. Press “
3
” for NEW FIRMWARE
,
then the “
*
” key to
scroll through the files.
6. When the desired software version is shown on the
display press the “
#
” key.
7. The selected software will be loaded and verified
(this will take about 30 seconds).
8. After the software has been loaded the vendor will
re-boot, and display will show the new software
number, version and name.
9. Remove the chip – some boards have push-push
sockets and others will require you to pull the micro
SD Card out with a fingernail.
10. All of the Board’s previous setting should be
retained, but it is always a good idea to be sure
everything remains set as you desire. Check
options and set prices as needed.
11. Store the micro SD card in a safe place.
Note:
DEX data will be cleared during this process. If necessary,
perform a DEX read before performing this upgrade to ensure
that you have a continuous record.
The small program that starts the sequence of loading the
program into the Control Board’s memory, is known as a
boot
loader
. This can be upgraded in the same manner as firmware,
but prices will NOT be saved. This firmware is changed only
rarely.
SAVING AND TRANFERRING MACHINE SETTINGS
(CONFIGURATIONS)
A time-saving feature of the Sensit 3 Control Board is the ability
to save and restore the machine settings that reside in the
memory system on each Control Board. These can be saved to a
file on the microSD card and transferred to another Board.
Important!
All Files on the microSD Card must
be saved in the top level (or ‘root’) Directory.
The Control Board will not look into other
folders for the files it needs.
