iNet series is the converter designed by PORIS for industrial development of control system , including ：
RS-232/422 to RS-485 ,RS-485 repeater, RS-232/422/RS-485 to Fiber, Ethernet to Fiber, Ethernet Switch....

The ET-SW/F2R3 consists of two fiber optic and three RJ-45 ports. With fiber optic, you can prevent noise interference from the system and transmission distance for up to 2 km (multi mode) or 20 km (single mode).
Moreover, the above products provide industrial grade design to assure flexibility, reliability and ability.
Thus, the ET-SW is especially suited for industrial environment with Ethernet networking needs.

The C232-485i converter lets you take advantage of RS-422 and RS-485 on systems originally equipped with RS-232.
It transparently converts RS-232 signals into isolated RS-422 or RS-485 signals.You do not need to change your PC's hardware or your software.
The C232-485i lets you easily build an industrial grade, long distance communication system with standard PC hardware.
The Repeat_ 485i repeater simply amplifies, or boosts, existing RS-422/485 signals to enable them to cover longer distances.
It extends the communication distance by 4000 ft. (1200 m)
The S-Fiber can be used as an RS-232 point-to-point or RS-485 point-tomultipoints for transmitting and converting full/halfduplex signals and their equivalents within a fiber optic environment.
