    Can't see your image. Too big perhaps? Post link.

    Do you mean the type of wire or the discrete devices circled?

    Sir REZA MALHAVI . . . . .

    What is the type of 2 wireconnection?

    Looking a the wording of core on the left and the word shield on the right, is being the use of a shielded cable between the diode sets and the RS232 connector.

    The illustration serves both as a pic of the cable type AND the manner of a very neat extraction method of the inner core wire from the shielding as well asalso then leaving a neat shield pigtail . . . . WITHOUT destroying many of the shield strands.
    Also, you want to go right up to the diode pair and leave minimum diode wiring exposed . . . or you would have defeated the purpose of the use of shielded interconnect wiring.


    Shielded wire with its outer braided shield and inner core wire . . . .

    What it cannot "tell" you is that you initially push the braiding down such that it greatly expands apart, and leaves big X cross gaps and you then spread an X crossing even further apart such thatt you can then get a . . . .needle / wire hook . . . down inside to flick a folded loop of the wire out, then you pull that wire end out totally, The pic is showing the mid state of that operation.

    The RX connection has a two diodes connected back to back so will never pass any current.

    the sensor use mod-bus protocol , I want to read sensor data by an Arduino. I don't know that the 2 wire connection is RS485 or other connections.
    you can see the sensor that connected by infrared then 2 wire output and rs232 interface .
    please help me about this type of connection.

    Thank you.
    I don't have any problem by shield connection, I wanna connect this sensor to Arduino or Esp8266 and use mod-bus library to read and log this.
    then please help me about the type of connection .
