FUTEK JK-485YG is an isolation repeater that can realize RS-485/RS-422 signal high-speed isolation relay. By isolating and amplifying the signal, it can extend the RS-485/422 communication distance and anti-interference. Full duplex, half duplex, external +5V power supply. The relay distance is greater than 1.2Km, the rate is: 0~150Kbps self-adaptive.
The JK‑485YG is a compact RS‑485/RS‑422 transceiver module that supports both half‑duplex and full‑duplex communication. It can transmit over distances up to 1.2 km with baud rates ranging from 0 to 150 kbps, and operates from a 5 V DC supply.
This manual describes the module’s pin assignments, wiring connections, and usage notes. It includes details on configuring half‑duplex and full‑duplex modes, required termination resistors for long lines, and power/ground pin locations. This manual is written in Chinese.
