• An IBM PC-compatible computer running Windows
• A parallel printer port (this is a 25-pin socket on the
• A standard 25-pin, straight-through, male-to-female
• A DC power supply capable of supplying any volt-

The user interface is easy to operate. Use the mouse,
or press the Tab key to navigate with the arrow keys.
Each of the buttons corresponds to bits in the com-
mand and configuration bytes. By clicking on them, the
correct SMBus write operation is generated to update
the internal registers.
Note: Words in bold are user-selectable features in the
software.
The program continually polls the device for new tem-
perature data and status, and monitors for alert condi-
tions. To disable the continuous polling of data,
uncheck the Automatic Read checkbox. To change
the T
select the appropriate data field and type in the new
value. Pressing Enter, after typing in the new values,
updates the internal registers.
If an interrupt condition is generated by the tempera-
ture crossing one of the alarm threshold levels, the
message ALERT will appear. To clear the interrupt, first
eliminate the condition that caused it and then click on
Read Alert. This action reads the Alert Response
address, returns the value of the current MAX6654
slave address, and clears the interrupt. Note: The least
significant bit (LSB) of the address is the read/write sta-
tus bit; therefore, the address returned will be 1 higher.
To make single-shot conversions, check the STOP
checkbox under Configuration Byte, and then click on
the One-Shot button. Single-shot conversions can also
be performed while the device is autoconverting. The
