Features
There are many RS-232 devices in industry applications. Nowadays it becomes important to link all those RS-232 devices together for automation & information. Usually those RS-232 devices are far away from the host-PC & widely distributed in the factory. So it is not a good idea to use multi-serial cards to connect all these RS-232 devices together. Our I-752N series products can be used to link multiple RS-232 devices by single RS-485 network. The RS-485 is famous for it's easy maintenance, simple cabling, stable, reliable and low cost. When the user want to connect RS-232 devices to 10BASE T, our I-7188EN can meet this demand. Refer to I-7188EN literatures for further information.
