Interface Circuit
Note 1: CMOS output circuit, the maximum output current is 4mA when working with 5V voltage, and the maximum output current is 2mA when working with 3V voltage.
Note 2: For long-distance transmission, a resistor of about 51K can be connected in parallel to the input end of the secondary instrument to improve the anti-interference performance.
Note 3: In PD pulse with direction signal output mode, there is no Z signal.
