    Four input switch data acquisition module

default   by2pattern  Interval only0.2Automatically send once per second，compatible“55”instructions

instructions55，Output switch state，The normal isF0H,The higher four bits of the signal correspond to the displacement0，as70H、B0H、50Hwait，

    Baud rate9600bps

    When there is no input signal in four inputs

The red light is，Power indication；The yellow light is a communication indicator。

1、instructions：Single byte  55 （hexadecimal/HEX）

   TX:55

   RX:F0 (4It's all input Open circuit or high level)

   The modules are4Three modes

     1、Mode one：Need to send“55”instructions，It will not be sent automatically

     2、Mode 2：Interval only0.2Automatically send once per second，compatible“55”instructions

     3、Mode 3：Only state changes are automatically sent once，compatible“55”instructions

     4、Mode 4：It is automatically sent once when there is a state change，There is no state change and it is automatically sent once per second。compatible“55”instructions

2、Change to Mode one Use only“55”Instruction reading（It will not be sent automatically）

   TX:5A 50 

   RX:A0

3、Change to Mode 2   

   TX:5A 5C 

   RX:AC

4、Change to Mode 3   

   TX:5A 5D

   RX:AD

5、Change to Mode 4   

   TX:5A 5E 

   RX:AE

Switch input explain

 1、Passive air contact input（Mechanical switch、Key、Button、Relay contacts, etc）

    On off One point to common（G）-Black line。

           Another point S0-S1One of the lines。

 2、Active input（fingerNPNThree wire proximity switch、Photoelectric switch, etc）

   A、Active switch

    The negative wire of the switch is connected to the ground  Public terminal（G）-Connect to black line。

    Signal wire connection of switch  S0-S3One of the lines。

    B、Equipment output signal

    When the signal terminal is at high level  And the negative pole of the power supply Voltage greater than3V

    When the signal terminal is at low level  And the negative pole of the power supply Voltage less than0.5V

3、If usedPNPsensor or It is the signal of high level and suspended change。

    Please leave a message，（meetPNPsensor）
