The ATC-277MM is a fiber-optic modem, which enables the connection of RS232/422/485 devices through a cable in multimode fiber.
The device allows the connection up to 2 km of fiber cables and supports point-to-point mode or Ring (dot-multipoint).
It supports data rates of up to 250kbps and allows devices with different interfaces to be coupled. This means the ATC-277MM can replace interface converters and isolators when connecting remote devices, preserving the EMI/RFI characteristics and transient immunity of fiber optics.
The device supports both transmit and receive lines, and offers full hardware control of the RS-422/485 driver with automatic circuitry for checking the shipped data.
All serial connections are available on the DB9-M female connector or 6-pin removable terminal, while the optical fiber is connected via ST or SC connectors depending on the version chosen.
The unit is powered from 9 to 24Vdc 250mA max.
The product is supplied complete with the following accessories:
- DB9F-DB9F cross cable
- Power adapter
An adapter is optionally available to enable DIN rail mounting(See link).
