Standard Serial to
Fiber Optic Converters
Models FOSTCDR, FOSTCDR-INV
The FOSTCDRx line of fiber optic converters are suitable for standard industrial
installations. These converters extend data communications up to 4 km (2.5 mi)
and provide two-way optical isolation on the input and output lines.
Model FOSTCDR industrial serial to multimode fiber optic converter, 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 other devices around a fiber optic ring. Since the FOSTCDR
supports mixed serial standards, you can replace other converters and isolators
and add the EMI/RFI immunity inherent to fiber optic communications.
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. In RS-232 mode, it supports Transmit
and Receive data. Handshaking signals are not passed through.
Model FOSTCDR-INV features an “inverted fiber state” and is suitable for
applications requiring the fiber optic light to be Off in the idle state.
• Data rates up to 115.2 kbps
• 4 km (2.5 mi) range
• 10 to 30 VDC input voltage
• Wide operating temperature
• 2000V, 2-way isolation
• Modbus ASCII/RTU compatible
• EMI/RFI protection
• TD, RD and Power LED's

What is the difference between Model FOSTCDR
and Model FOSTCDR-INV?
The FOSTCDR 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 FOSTCDR-INV is the opposite. The fiber is Off in the idle state.
* Fiber is Off in the idle state.
