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,

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

fiber.
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

light Off/On in step with the data. This model has an indicator for Transmit and
state.
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.
