SN65HVD3082E: SN65HVD3082EDR signal issue

Ceano Huang

Part Number: SN65HVD3082E

Hi 

We use SN65HVD3082EDR to convert UART to RS485
But why the signal is abnormal

Please help clarify the problem

CH2 : RS-485 input (pin6 and pin7)

CH3 : Enable signal (pin2 and pin3)

CH4 : UART output signal (pin1)

Schematic as below
