DS2775–DS2778 Evaluation Kits
If the MAC is “Not Verified,” make sure that the chal-
lenge was written prior to computing the MAC. If the
“Not Verified” error continues, perhaps the secret in the
device does not match what is in the Secret text boxes
and the user needs to clear the secret of the DS2776/
DS2778.
The Parameters tab gives the user access to the entire
parameter EEPROM memory block (block 1, addresses
60h–7Fh) in terms of application units and device units.
The Application Units subtab displays the parameters
in units like mA, mAhrs, and V (Figure 24). The Device
Units (Read Only) subtab performs the calculations
needed to get the application units into the units that
are stored in the device like µV, µVhrs, and ppm as well

as show the hexadecimal values that are written to the
device.
The Application Units subtab allows the user to read
and write the parameter EEPROM memory block. To
change any of this information, simply click on the
desired text field and enter the new value.
Clicking on the Load Default Set Up button enters
example data into the information fields of the
Application Units subtab. Once all data is in the
desired format, click on the Write & Copy button to
copy it to the DS2775–DS2778’s EEPROM.
This information can also be stored to a file and
recalled later using the Load Set up or Save Set Up
buttons or the Load Parameter Set up or Save
Parameter Set up option from the File menu (Figure 4).
