SER-485-FXC Industrial Isolated Converter
SER-485-FXC ^{N-Tron Networking Series}
THE IND^InUS^dT^uRI^sA^tL^rN^iaET^l W^IsO^oRK^laC^tO^eM^dPA^CNY^onverter
The SER-485-FXC is our premium Industrial Serial to
Multi-mode Fiber Optic Converter. Designed for
rugged industrial environments, it is UL approved and
certified for use in Class 1 Division 2 environments. In
addition to direct point-to-point connectivity, it is capable of
operating in a multi-drop mode. This allows one se-
rial 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.
PRODUCT FEATURES
• Data Rates up to 115.2 kbps
• 10 – 48 VDC Input Power Range
• Wide Operating Temperature
• 3-Way 2000V Optical Isolation
• MODBUS ASCII/RTU Compatible
• EMI / RFI Protection
• UL Class 1 DIV 2
• Built-in, Switchable Termination & Bias
PRODUCT OVERVIEW
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. The serial data and power cables connect to
removable terminal blocks. ST connectors are used for the fiber.
