Red Lion's N-Tron® series SER industrial serial devices provide signal conversion, isolation, or rebroadcast functions. The SER-485-FXC provides RS-232, RS-422, or RS-485 communications up to 3.5 km over a fiber optic network. The SER-485-IS provides RS-422 to RS-485 signal isolation and conversion, while the SER-485-IR is a serial signal repeater.

The SER product line is designed for rugged industrial environments, and is UL listed for use in Class 1 Div. 2 environments. The SER-485-FXC industrial serial to fiber converters support two operating modes including direct point-to-point connectivity, and it is capable of operating in a multi-drop mode. This allows one serial device to communicate with up to 31 other devices around a fiber ring. The SER-485-IC provides signal isolation on both data ports and converts RS-232, RS-422, and RS-485. The SER-485-IR offers powerful optical isolation ensuring ground loops don’t interfere with sensitive signaling equipment.
