Features:

    This module fully considers the 485 bus lightning protection design and anti-interference design.
    It has extremely high EMC (electromagnetic compatibility) and EMI (electromagnetic anti-interference) performance.
    When long-distance transmission in the field, the module is connected to the earth Access to the earth can play a good role in anti-interference and lightning protection, making the 485 bus more secure; the indoor short-distance transmission can not be connected to the earth.
    With standard 2.54 pitch pin headers for your secondary development
    With 120 ohm matching resistance, short-circuit R0 to enable matching resistance, short-circuit is recommended for long-distance transmission.
    Support multi-machine communication, at least 40 nodes can be connected to the same network
    It can be hot-swapped and there will be no signal thrombosis
    Anti-interference wiring and copper laying method to prevent signal interference
