Upgrading the Firmware
42
8.5" Black and White Touch Panels
.
8.
Using the new EPROMs, match up the socket holes to their respective prong and the notches to
the correct direction for both the new Odd and Even chips.
9.
Insert all the prongs simultaneously until each is firmly resting in its socket hole and the entire
chip is securely connected to its base.
10.
Rotate the circuit card back to the original position and place it in the touch panel housing.
11.
Plug the 2-pin power or AXlink connector back into the touch panel for approximately
1 minute. Once you can confirm the panel is receiving power, remove the connector, align the
screw hole and insert the Phillips-head screw and tighten.
12.
Replace the bottom panel and align the screw holes. Insert the seven Phillips-head screws and
tighten.
13.
Plug all connectors back into the touch panel.
AXM-LC (/PB) and AXD-LC (/PB) EPROM Replacement
If the unit is already mounted to a surface, remove it at this time. Refer to the
Installation
section on
page 3 for more information.
1.
Discharge the static electricity from your body by touching a grounded object.
2.
Remove the 2-pin power connector from the rear side of the panel. If you are using power via
AXlink, remove the AXlink connector.
3.
Flip the touch panel face down onto a soft cloth, and remove the seven Phillips-head screws
from the bottom panel. Then, gently remove the housing.
4.
Remove the Phillips-head screw located in the center of the circuit card.
5.
Gently tilt the circuit card down towards the connector side and pull backwards until you clear
the connector housing. Then, slowly rotate the circuit card backwards until you can lay it down
flat with the EPROMs exposed as seen in FIG. 17. EPROMS have stickers that indicating the
firmware version.
6.
Carefully remove each EPROM by inserting a Phillips screwdriver with a non-conducting flat-
blade between the EPROM and the connection site (at the notch side).
7.
Gently pry the EPROMs from their connection base until they begin to loosen. Carefully pull
them out by either using an EPROM removal device or by gently pulling them from their base
(making sure to evenly pull the prongs from their socket holes).
Insert the EPROMs with the notches facing the correct direction. Match the Even and
Odd EPROM placement with the location shown above.
During the replacement process, cables may be pulled from their connections and
should be re-checked to confirm they are securely connected.
