Dumping the Reader’s 640K Conventional Memory
9-12
If you cannot resume the reader, you may need to cold boot the reader or load
flash memory to resolve the error condition. However, all data in conventional
memory will be lost when you perform either of these tasks.
You can save the contents of the reader’s 640K conventional memory by
dumping it to a host computer. The host computer must be running a
communications program that can receive and store the data from the reader’s
memory.
To dump the reader’s 640K conventional memory to a host computer
1. Connect the reader to a host computer using the optical link adapter or the
communications dock. The reader transmits and receives data at 4800 baud,
no parity, 8 data bits, and 1 stop bit.
2. Run a communications program, such as Crosstalk, that saves data on the
host computer. This program is not provided with the reader.
3. Display the Boot Loader menu:
a. Press to turn off the reader.
b. Press - -.
c. Press .
d. Press to turn on the reader.

enter the correct password after three attempts, the reader resumes
normal operation.
