Inline RS-232 to RS-422/485 Serial Converters

Whether converting RS-232, RS-422, RS-485, or transistor-transistor logic (TTL) serial communications, Advantech offers a variety of inline serial converters to make it as easy as possible to convert communication mediums.

The BB-4WSD9OTB or BB-4WSD25OTB converters fill the needs for RS-232 to RS-422 or RS-485 (2- or 4-wire) serial conversion with 2,000 V two-way optical isolation and 115.2 kbps data rate.

The BB-485OI9TB isolated converter converts unbalanced, full-duplex RS-232 signals to balanced full-duplex (4-wire) RS-422/485 or half-duplex (2-wire) RS-485 signals with up to a 9600 bps data rate.

The BB-232LPTTL and BB-232LPTTL33 converters will fit users’ needs when looking for 5 TTL and 3.3 TTL to RS-232 conversion with no power supply required.

The model BB-9PFLST allows any two RS-232 asynchronous serial devices to communicate full-duplex over two multi-mode fibers. Typical distances of up to 4 km (2.5 miles) are possible with no external power required.
