Appendix L
Firmware Upgrades
This section applies only to the WDP P11/12 and the WDP P01, the separate external
box decoder models. It does not apply to the Integrated WDP Models.
Occasionally it will be necessary to get firmware fixes for problems discovered with
the external WDP Reader, especially in the early stages of each advance in
development. This is accomplished replacing the EPROM, a chip which is to
replace the similar chip on the board of the WDP's decoder box. The EPROM
chip on the board is labeled with a white paper label to indicate the firmware
version and to communicate the "Copyright Notice".
To replace the EPROM, remove the cover to the WDP decoder box according to
instructions in Appendix A (see the diagram below).
If you have a Integrated models of the WDP, you will have to send the unit back
for a firmware change at the factory.
Remove the EPROM by gently prying with a small flat head screw driver --
alternate ends to keep from bending the metal legs.
