» Introduction There are many RS-232 devices in industry applications. Nowadays it becomes important to link all those RS-232 devices together for automation & information collection. 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 multiserial cards to connect all these RS-232 devices together. Our I-752N series products can be used to link multiple RS-232 devices using a single RS-485 network. The RS-485 is famous for it’s easy maintenance, simple cabling, reliablity and low cost. When the user wants to connect RS-232 devices to 10 BaseT, our I-7188EN series products can meet this demand. » Can be used as an Addressable RS-485 to RS-232 Converter Basically our I-752N products are Master-type converters. The I-752N uses our R.O.C. Patent 086674. Other competitor’s converters are Slave-type and can’t work independently without a host-PC. In real industrial application, the demand is different case by case and customers are not satisfied with Slave-type devices. The I-752N is very powerful and can analyse the local RS-232 device, D/I or D/O without a host-PC. » Can be used as an Embedded Controller Can be used as RS-485 to RS-232 Device Server The Device Server is an appliance that network enables any device with a serial communication port. Our Intelligent Communication Controllers allow those devices to become connected to the RS-485 network. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
