I-752N series addressable RS-485 to RS-232 converter

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. I-752N has one RS-485 port and several RS-232/422 ports. It can assign a RS-485 address number to each RS-232/422 port. By the functionality, the host PC can send data to specific RS-232/422 device link to the I-752N via the RS-485. And the data won't case network conflict.
