Typical distances up to 4 km (2.5 mi) are possible with no external power required. The BB-9PFLST supports both data signals at up to 115.2 kbps as well as the RTS/CTS handshake lines. This means model BB-9PFLST can replace short haul modems and isolators when connecting remote devices, while providing the EMI/RFI and transient immunity of optical fiber. RS-232 connections are provided on the same DB9 female connector, while the multi-mode fiber is connected via two ST connectors. The unit is port-powered by the RS-232 Transmit Data and handshake lines. When handshake lines are not available, or when using a low power RS-232 port, the BB-9PFLST can be powered by an external 12VDC supply, drawing 50 mA maximum (power supply not included, sold separately).<br>
