Firmware Change
This procedure outlines the mechanical installation steps required to install a PROM in the UDACT-F.
Handling precautions for integrated circuits
Static electricity can destroy integrated circuits (ICs)! To prevent damage to the PROM, a wrist strap and a
static-free PLCC IC insertion/extraction tool is highly recommended. The manufacturer cannot be respon-
sible for damage to the PROM as a result of improper handling.
System Power Sources
Always remove power before working on the UDACT-F!
Integrated Circuit Pin Conversion
Observe proper orientation of any IC removed or installed! Note location of Pin 1 with respect to the flattened
corner and dot on the body of the IC and the relationship to the flattened corner on the IC socket. The
replacement PROM must be installed in the same manner as the PROM removed. Failure to observe this
orientation will result in destruction of the PROM.
