MSC CXC-BT

User Manual

36 / 84

TACHO

Input for the tacho signal from the fan (open collector); two pulses / rotation

PWM

PWM output signal for fan speed control.

Caution!

Using the power supply wide input range at more than +12V can damage the fan. The

correct function of the fan is not guaranteed below +12V.

WATCHDOG

The CXC-BT board has a watchdog function implemented by an embedded controller.

The watchdog can be enabled and configured in the BIOS Setup.

If the watchdog is enabled a counter is started which generates a reset if it is not retriggered within a
programmable time window.

Possible watchdog delays: 1s, 5s, 10s, 30s, 1min, 5min, 10min, 30min Possible watchdog timeout: 0.4s,
1s, 5s, 10s, 30s, 1min, 5min, 10min The time delay starts as soon as it is enabled in the BIOS.

MSC provides a software API which gives the application software access to the Watchdog functionality
if needed.
