Figures 1 through 3 on the following pages show and
describe the external parts of the PTC-960L. The part
listed below is internal and, therefore, is not shown in
any of the figures.
Flash EPROM
A flash EPROM is an electronic component installed
inside the PTC. It contains the PTC’s data collection
program and determines the PTC’s key functions, the
display prompts and messages, and how and when
the PTC prints or transmits data.
For details on erasing and repro-
gramming flash EPROMS, refer to
the
Guide to the Flash Utilities (TCAL or
MS-DOS Version
).
The flash EPROM can be erased and reprogrammed
while it is inside the PTC. First, the PTC must be
connected to a host computer, via a cable or by being
placed in a communication cradle. Then, using
software in the PTC’s operating system, you can erase
the flash EPROM and reprogram it with a new
program from the host computer.
