Name and Function/Connection
Remote
Remote1+
18
Remote Thermal
Diode Positive
Input
Positive input (current source) from the first remote thermal diode.
Serves as the positive input into the A/D. Connected to
THERMDA pin of Pentium processor or the base of a diode
connected MMBT3904 NPN transistor.
Remote1
17
Remote Thermal
Diode Negative
Input
Negative input (current sink) from the first remote thermal diode.
Serves as the negative input into the A/D. Connected to
THERMDC pin of Pentium processor or the emmiter of a diode
connected MMBT3904 NPN transistor.
Remote2+
16
Remote Thermal
Diode Positive
Output
Positive input (current source) from the first remote thermal diode.
Serves as the positive input into the A/D. Connected to
THERMDA pin of Pentium processor or the base of a diode
connected MMBT3904 NPN transistor.
Remote2

Remote Thermal
Diode Negative
Input
Negative input (current sink) from the first remote thermal diode.
Serves as the negative input into the A/D. Connected to
THERMDC pin of Pentium processor or the emmiter of a diode
connected MMBT3904 NPN transistor.
Fan
Tachometer
Inputs
TACH1
11
Digital Input
Input for monitoring tachometer output of fan 1.
TACH2
12
