The CommFront FBR-Serial-2 carries asynchronous serial communications (RS-232, RS-485, RS-422) over fibre optic cable. The converters work in pairs (point to point), and the fibre link is immune to radio and electrical interference, surges and ground loops; the multimode version extends the link up to 5 km. Standards can be mixed – RS-232 at one end and RS-485/422 at the other –, data format and rate (up to 115.2 kbps) are detected automatically, and with RS-485 no flow control is needed. The rugged ABS housing mounts directly on a DIN rail or wall, with built-in 600 W surge and 15 kV ESD protection. Power 9–30 V DC; the supplied power adapter has a US plug (type A).
