STATE
lines of a NetPing mini-UPS device.
Terminal 1 –. GND
Terminal 2 – IO Line 2
Terminal 3 – IO Line 1
Logic level 0 – no more than 0.3 V. Logic level 1 – no more than 0.7 V. A maximum allowable voltage is 5 V.
Electric parameters of IO lines
In the «output» mode:
the voltage of logic «1»: mai3,3V 2mA (is not used as the output);
the voltage of logic «0»: maintains 0 V, 2 mA (is not used as the output).
In the «input» mode:
voltage of logic «1»: > 2,31 V;
voltage of logic «0»: < 0,99 V.
The functionality of this terminal block is not implemented in the firmware of the device, so in practice it
cannot yet be used.
