Verify Ram From Serial Port - Data I/O 298 Manual

3.6.7 VERIFY RAM FROM SERIAL PORT
Use the following front panel keyboard procedure to verify
that the RAM data is the same as the incoming serial port
data:
1. Set-up the seriai port. Refer to section 2.

The prompt
(A.)
preceding "ADDR" in the display
means that you can change the begin RAM address to
any address within the range of RAM word limit by
entering the address hex value with the keyboard. If an
entry is not made, the value defaults to the first
incoming address. If a hex value appears in place of
"ADDR," it is from a previously entered begin address.
a. If the hex value that appears in place of "ADDR" is
correct, go to step 5.
b. If it is incorrect, enter the correct hex value.
c. If you do not wish to change the begin device
address or block size {step 5), go to step 6.

change the block size by entering the hex value with the
keyboard. if an entry is not made, the value defaults to
RAM size minus the begin RAM address. If a hex value
appears in place of "SIZE," it is from a previously
entered block size.

NOTE
The amount of time the programmer will
require to perform this operation will vary
depending on the data format, block size,
and baud rate. The action symbol
character rotates while the operation is
taking place.
8. When the operation is complete, the following display
signals the programmer's readiness. If an error code is
displayed, see appendix E.
NOTE
HHHH is the hex sumcheck of all the
device data. If block limits are set the
sumcheck (HHHHJ will be calculated oniy
for the block size.
9. To repeat the verify operation, return to step 7.
