1.1 Product OverviewAQTH-0104NI is an isolated RS485 hub that supports one RS485 master and four RS485 slaves. It adopts asynchronous half-duplex communication and each RS485 interface adopts independent driving mode. Each RS485 interface and power supply isolated from each other, all the RS485 ports are also isolated from each other. Each port has its own independent driving capability. Each 485 port corresponds to one indicator light respectively. During communication, the corresponding green light flashes.1.2 functionAQTH-0104NI is mainly used to solve the problem of compatibility of 485 power supply between devices and common mode voltage interference. The hazards of power sharing between equipment are given in Section 5.1.1.3 Product Features1. Support power supply voltage 9V ~ 60V2. Support all the way 485 master and four 485 slave3. The highest baud rate 115200bps, baud rate adaptive4. 485 between each, and all isolation between 485 and power5.

Matters needing attention1) Hub power supply voltage should be between 9 ~ 60V. If the voltage is over-voltage, the power may burn the hub. the voltage is too low, may lead to the hub does not work.2) Note that the hub is not damp, do not manually change the hub circuit or the components on the hub board short circuit.3) In the event of a hub failure, the user should contact the company promptly, shall not be unauthorized repair and replacement parts.4) Please carefully read the user's attention and warranty instru
