The
ATC-277SM is a Single Mode Optical Fiber Modem, that allow the connection
of RS232/422/485 devices over a single-mode fiber cable.
The device allows connection over up to 20Km of fiber cable and supports point
to point or ring (point to multipoint) networking.
The converter can also be
used as "Repeater" to create
a multi-drop master/slave configuration, allowing one serial device to talk
to multiple slave devices around a fiber ring.
It supports data rates up to
250K bps. Different standards can be mixed and matched to allow RS-232 devices
to connect to your RS-422 or RS-485 system. This means the ATC-277SM can
replace converters and isolators when connecting remote devices, while providing
the EMI/RFI and transient immunity of optical fiber.
The ATC-277SM supports
both the Transmit and Receive data lines, and provides full hardware control
of the RS-422/485 driver with automatic Send Data Control circuit.
All serial connections are provided
on the DB-9 female connector or 6-pin extractable TB, while the single-mode
fiber is connected via two SC connectors.
The unit is powered from 9 to 24Vdc at 250mA max.
