What is the default state of SP in CD1020?

Before SP ports and input ports are configured.

Hi,

Before SP ports and input ports are configured, the SP pin is tri-state, and the value of state of  SP depends on the voltage on the SP pin.

The default configure of the SP pin is Switch to Battery (SB). 

If the Voltage is <4V , the state should be  0-open switch.

If the voltage is >4V, the state should be 1-closed switch.

I hope this answers your question.

Best regards,

Tomas

Hi,

For SG pins, if the voltage is > 4V, the state is open (0). If the voltage is < 4V, the state is closed (1).

Best regards,
