ADAM-4515
Isolated CAN Repeater
Introduction
Most industrial computer systems come with
standard RS-232 serial ports. Though widely
used and accepted, RS-232 connections have
limited transmission speed and networking
capabilities. CAN (Controller Area Network) is a
serial bus system with multimaster and real-time
capability. It is a cost-effective Fieldbus for
device networking in manufacturing plants. The
ADAM-4515 repeater is a family of products that
extend a communication cable’s length in CAN
V2.0 systems. By allowing the user to extend the
bus length at any given speed, ADAM-4515
repeaters assist the user to cost-effectively
implement I/O or other nodes on these buses at
remote locations. Implementing I/O or other
nodes without an ADAM-4515 would be more
difficult and expensive. The ADAM-4515
repeater simply amplifies or boosts existing CAN
signals to enable them to cover long distances
from 40 m to 1000 m according to the data
transfer rate. ADAM-4515 repeaters also allow
users to increase the maximum number of
connected nodes up to 64.
