【Summarize】
The product is RS-485 HUB is designed for RS-485 system in
complicated
electromagnetic
environment.
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℃.
