CHANGING THE RAM DATA
The Model MSOP system allows the operator to change the RAM of each handler CPU.
To access the Change RAM Mode:
Press the
[SET UP]
key. The message
CHANGE RAM? NO
will appear.
Press the
[SET UP]
key again. The message
CHANGE RAM? YES
will appear.
Press
[Enter]
. The message
LOAD DEFAULT NO
will appear. If you choose
LOAD DEFAULT NO
, the
handler will leave all RAM addresses as they were. From here, you may proceed in either of two
directions:
a. If you wish to make specific changes to the RAM, press
[Enter]
again. You
have chosen not to load the default (ROM) values. The display will read,
“
0090DATA 01
”
b. If you do wish to set the RAM with ROM values, press the
[SET UP]
key. The
message
LOAD DEFAULT YES
will appear. Press
[Enter]
.
When you choose
LOAD DEFAULT YES
, the handler loads all default addresses from the EPROM to the
RAM. This is called
“Blasting the RAM”
After you have loaded the EPROM into the RAM, you may still make
specific RAM changes if you wish, as described below.
1. Press the
[SET UP]
key or the
[TOTALS]
key to scroll through the firmware addresses:
The
[SET UP]
key will scroll the address up.
The
[TOTALS]
key will scroll the address down.
2. When you reach the firmware address desired, press the
[Space]
key to increment the
upper data nibble in any individual address, as desired. Press the
[Delete]
key to
increment the lower data nibble in any individual address, as desired.
The minus key,
[–]
, sets a specific address to FF. The zero key
[0]
, sets a specific address
to 00.
NOTE: Pressing the [Clear] key loads the default value from the EPROM into the RAM for a specific
address only.
3. To exit the Change RAM mode, press the
[Enter]
key.
The message
MOD SET UP? NO
will appear.
4. If you wish to modify any of the set-up information you just entered, press the
[SET UP]
key to display “
MOD SET UP? YES
” and make your corrections now.
5. If not, press
[Enter]
again to return to the previous mode.
NOTE:
Make certain to write down and retain any changes you make to the RAM. If you do not, you will
regret this later. Permanent selections should be programmed into the EPROM. Please contact Exatron for
assistance in doing so. Our toll-free telephone number is 1-800-EXA-TRON.
