Tel: +86-755-26702668 Fax: +86-755-26703485 www.3onedata.com 【Summarize】 The product is RS-485 HUB is designed for RS-485 system in complicated electromagnetic environment. It supports a transmission rate up to 115.2KBPS, and adopts two-way transparent transmission, which allows one RS-485 bus or one RS-232 bus to be divided into 4 RS-485 buses, or any divided RS-485 signal to be transparently transmitted to host computer RS-485 or RS-232 hub. Each RS-485 port of slave computer is provided with reverse connection alarm and protection function, with which the reliability of existing RS-485 network is greatly improved, effectively reducing the network maintenance time. To ensure the security and reliability of data communication, the RS-485 ports are provided with 2KVAC isolation protection, level-4 electrostatic protection and level-2 radiated susceptibility, effectively preventing surge current, common ground and radiated interference, making the hub safe and reliable and suitable for outdoor application. The product also comes with RS-485 bus star connection. Users can easily improve RS-485 bus structure and divide the network segment. Proper utilization of HUB device can help design a unique and reliable RS-485 system. The product adopts EMC protection and supports DIN-rail installation, allowing it to be used reliably in severe environment at a temperature of -40℃ ~75℃. 【Packing list】 The RS232/RS485 converter is shipped with the following items.

The HUB device has 4 slave computer RS-485 serial ports, and each port has reverse connect protection function, and can work in shutdown mode. Any RS-485 port reverse connection will only affect its RS-485 BUS system, will not affect the normal work of other interface connected with RS-485 system. Users can quickly determine fault port and other connected devices according to the fault alarm light. Note: The connection of slave computer RS-485 serial ports of the same HUB device is wrong connection. 【LED Indicator】 LED indictor light on the front panel of product, the function of each LED is described in the table as below. System Indication LED LED Statue Description PWR ON Power is being supplied/working well OFF Power is not being supplied/ not working well TXD Blinking Data is being transmitted OFF No data is being transmitted RXD Blinking Data is being received OFF No data is being received 1~4 ON Power is on the device, the corresponding interface of D1~D4 is on the state of data receive/transmit Blinking The corresponding interface of D1~D4 is transmitting/receiving data OFF Fault alarm: Power is not on the device or power is on the device but the corresponding interface of D1~D4 is reversed 【Installation】 - 3 - Before installation, confirm that the work environment meet the installation require, including the power needs and abundant space. Whether it is close to the connection equipment and other equipments are prepared or not. 1. Avoid in the sunshine, keep away from the heat fountainhead or the area where in intense EMI. 2.
