industrial Serial to Fiber optic Converters
FOSTCDRI, FOSTCDRI-INV
Model FOSTCDRI is B&B Electronics’ premium industrial serial to
multi-mode fiber optic converter. Its rugged design is UL approved and
certified for Class 1/Division 2 industrial environments. It extends data
communications up to 4km (2.5 miles) . It provides three-way optical
isolation on the input, output and power lines.
In addition to direct point-to-point connectivity, 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. Since it supports mixed standards,
you can replace other converters and isolators and add the EMI / RFI
protection inherent to fiber optic communications.
In RS-232 mode, the converter 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 external software.
Easy to install and configure, it has a 12-position DIP switch on the bottom
to configure RS-422/485 parameters. Serial data and power cables
connect to removable terminal blocks. ST connectors are used for the
fiber.
Model FOSTCDRI-INV features an “inverted fiber state” and is suitable
for applications requiring the fiber optic transmit light to be Off in the idle
state.

what is the difference between Model FostCdri
and Model FostCdri-inv?
The FOSTCDRI keeps the light in the fiber turned On when no data is
transmitted and the input signal is in the MARK state (idle). If light is lost or
too low, the electrical signals go to the SPACE state. The input signal turns the
light Off/On in step with the data. This model has an indicator for Transmit and
Receive, if no light is received, the RD LED will come on, the RD output will be
positive relative to GND (normally negative), and in RS-422 or RS-485 mode,
no light will set the TD(A)- line high relative to TD(B)+. The usual voltage with
light in the fiber and no signal sets the B line high relative to A (about 4.4 Volts
DC no termination).
The FOSTCDRI-INV is the opposite. The fiber is Off in the idle state.
