FUNCTION
RO
Receiver output: If A - B -50mV, RO is high; If A - B -200mV, RO is low; RO = High if A and B are unconnected (floating) or shorted.RE
Receiver output enable.RO is enabled when RE is low; RO is high impedance when RE is high.If the Rx enable function isn’t
required, connect RE directly to GND or through a 1k to 3k resistor to GND.DE
