SMCRead

As the program is being read from the card a ‘ . ’ is displayed for every 100
characters read from the card.
2.7 D — Store a .DLD Program File
This option is used to store a .DLD program file, as created by Edlog, into one
of the program areas of the card. SMCRead first displays the current status of
the program areas in the card to show you which areas are in use. Next
SMCRead asks you to enter the name of the .DLD file. SMCRead appends the
.DLD suffix if necessary.
You are now asked in which card program area you wish to store the program.
Enter a number between 1 and 8.
SMCRead now loads the program into the card, displaying a ‘ . ’ as each 100
characters is transferred.
2.8 E — Erase, Reset and Test the Card
The E option completely erases all data and programs in
the card. At the same time the card memory is fully
checked to ensure the module can store and recall data
correctly.
SMCRead asks you to verify that you want to erase the card before this option
runs. Press
Y
for yes or
N
for no as appropriate.
SMCRead runs the E option by issuing the ‘1248K’ command to the module
and displaying the status of the process. First a row of ‘+’ symbols is
displayed. One ‘+’ is displayed for each 16 kbyte page of memory written. At
the end of this row an equal number of ‘-’ symbols is shown as the data is read
out and checked successfully.
A further two rows of ‘-’ symbols are shown as further read/write tests are
performed on the memory.
If an error occurs at any stage an ‘x’ is displayed and tests on memory after
that page are aborted. After an error is detected the memory that can be used is
limited to the pages of good memory tested before the failure.
If an error does occur, use the E option several times to check if the position at
which the error occurs is repeatable. If the test fails at different points in the
card, the card may have a serious hardware fault. If the error always occurs in
the same memory page, it is possible to use the card with reduced capacity.
Please contact Campbell Scientific for further advice.
At the end of the test, SMCRead displays a message indicating how many
locations are usable.
