UPDATING SOFTWARE
Replacing the programmed PROM (Chip Change)
This is not necessary for all applications, but only those that occur in jurisdictions requiring
PROM to be installed.
Note: As soon as even one PROM has been installed into an acceptor module, the acceptor
module will not be able to be re-programmed with a CPM. To re-program an acceptor module
that has had a PROM installed, you MUST change or insert a new PROM (perform a chip
change). When power is re-applied, the Acceptor module will be re-programmed from the
PROM.
1. Remove the acceptor module from the chassis. (Instructions on how to remove it are on page
10).
2. Open the acceptor module by placing the palm of your hand on the front of the module and
placing your fingers around the top of the yellow cover as shown in the diagram below. Pull the
cover toward your hand and then lift up, opening the module head fully.
3. Remove the yellow cover from the acceptor module by turning the acceptor module so that the
top of the cover is facing you. Wedge the tips of your fingers underneath the left and right front
top corners of the yellow cover. Lift the cover’s corners out and then back toward you to release
the cover. The cover will be released once the cover has cleared the black ramps as shown in the
diagram below.
4. Once the yellow cover is released in the front, slide it back and remove it.
