Jumper Settings
LEDs indicate the status of the following signals
This EVB has many jumper configurations to evaluate all of the features of the EMC2101.
Device Power
To enable one of the 2 devices on the EVB, use jumpers J2 and J3. When a device is selected, the
appropriate LED will light as shown in
one device may be active at a time as both devices have the same SMBus address.
Fan Control
To adjust the fan control circuit one 3-way jumper is used. The two settings are DAC mode and PWM
mode. The default setting is PWM which requires the fan to be connected to FAN CONN. 1 and the
JP8 shorted from pin 1-2.
If the linear DAC mode is desired, several things need configured. First, JP8 must be shorted from pin
2-3 and the fan must be connected to FAN CONN. 2. Then, the device must be configured for linear
operation via the ChipMan software. Consult the datasheet for these
