Description

The BB-FOSTCDR is our Industrial Serial to Multimode Fibre Optic Converter. Designed for industry, it extends serial data range up to 2.5 miles and provides the most versatile connection possible between any asynchronous full or half-duplex serial equipment. In addition to direct point-to-point connectivity, it is capable operating in a multi-drop mode. This allows one serial device to communicate with up to 31 others around a fibre optic ring. Since it supports mixed serial standards, you can replace other converters and isolators and add the EMI/RFI immunity inherent to fibre optic communications.

In RS-232 mode, the BB-FOSTCDR supports transmit and receive data. Handshaking signals are not passed through.

An Automatic Send Data Control circuit controls the RS-422/485 driver chip, eliminating the requirement for special software.

Easy to install and configure, it has an 8 position DIP Switch to set up the RS-422/485 parameters and terminal blocks to connect serial signals and power.
