3.To push the stick of textool down to the PCB side. Now the EPROM will be tightly held in the textool socket.
Now you may key in a number from 1 to 6 to choice any function we mentioned before. Details are as follows:
1)WRITE: When you type”1”that means you will programing any a block of memory content into EPROMs. The next line come to the screen is:
START ADDRESS ?
just key in a start address of memory in hex code and hit RETURN.
BLANK ? (Y/N)
A.If you went to “burn” a blank EPROM, now insert
the EPROM and type “Yes”, will test EPROM blank automatically. ROM CHECK OK! (Means your eprom is ready to write)
SW ON
In case the EPROM has been programmed, Then ROM CHECK ERR!! (Means your eprom can't write) BLANK ? (Y/N)
Please change another one and do it again.
B.Sometimes you only want to correct data that already programmed in EPROM, So please type “No”.
The blank check procedure will be omitted and directly display:
SW ON
Now you just turn on the switch which is on the front
edge of
right down corner of the screen.
For 2716 it will take 95 seconds to fully programming, When the “burning” is completed, the screen display:
COMPARE OK !! SW OFF
Please turn the switch off and take the EPROM away from the TEXTOOL, a new fully programming EPROM has been produced. Or the screen displayed as:
COMPARE ERR !! SW OFF
