Connecting RS485 Communications Cables
By the RS485 communication line, connecting EVVO 20000TLG23P~EVVO 33000TLG23P to
communication equipment (such as data acquisition, PC terminal).
You are recommended to use 24 AWG outdoor shielded network cables with the internal
resistance less than or equal to 1.5 ohms/10 m and external diameter of 4.5 mm to 7.5 mm
as RS485 communications cables.
A waterproof RJ45 connector has six parts: plug, screw nut, seals, housing, sealing plug and
cable screw nut , as shown as follow.
