Full-Featured Evaluation Kit for the DS1702K includes
testing software for the DS1621, DS1721, DS1624,
DS1629, DS75, and DS1775 devices. The DS1702K
is comprised of five separate and unique software kits:
the DS1721K.exe (works for both the DS1621 and
DS1721), DS1624K.exe, DS1629K.exe, and the
DS75K.exe. Each software package works through the
same 2-wire DS1702K board (included in the
DS1702K kit) with jumper selections. The DS75K is
completely software compatible with the DS1775
device requirements. However, the SOT23-5 (5-pin
socket) is not provided.
The 2-wire board as shown in Figure 1.0 allows the user to
test the functional capabilities of each device. The circuitry
allows the user to read the temperature, and to read and
write the appropriate registers of the socketed device.
