your distributor or sales representative immediately.
CE/FCC Certification
ADAM-4510I and ADAM-4520I developed by
Advantech Co., Ltd. has passed the CE and FCC test
for environmental specifications. The test conditions
for passing including the equipment being operated
within an industrial enclosure. Therefore, in order to
protect the ADAM module from being damaged by
ESD, we strongly recommend that the use of CE-
compliant industrial enclosure products.
Overview
Most industrial computer systems come with RS-
232 serial ports. Though widely accepted, RS-232
has limited transmission speed, range and network-
ing capabilities. RS-422 and RS-485 standards over-
come these limitations by using differential voltage
lines for data and control signals.
ADAM-4520I is isolated converter for systems orig-
inally equipped with RS-232. It transparently con-
verts RS-232 signals into isolated RS-422 or RS-
485 signals. You don't need to change your PC's
hardware or your software. The ADAM-4520I lets
you easily build an industrial grade, long distance
communication system with standard PC hardware.
The ADAM-4510I repeaters simply amplify, or
boost, existing RS-485 signals to enable them to
cover longer distances. They extend the communi-
cation distance by 4000 ft (1200 m) or extend the
number of connected nodes by 32.

Industrial Design
Intelligent RS-485 Control
The RS-485 standard supports half-duplex commu-
nication. This means that just two wires are needed
to both transmit and receive data. Handshaking sig-
nals (such as RTS, Request to Send) are normally
used to control the direction of the data flow. A spe-
cial I/O circuit in ADAM-4510I and ADAM-4520I
automatically senses the direction of the data flow
and switches the transmission direction. No hand-
shaking signals are necessary. So you can build an
RS-485 network with just two wires. This RS-485
control is completely transparent to the user. Soft-
ware written for half-duplex RS-232 can work with-
out modification.
Isolation
ADAM-4510I and ADAM-4520I's opto-isolators
provide 3000 VDC isolation to protect the host com-
puter from ground loops and destructive voltage
spikes on the RS-485 data lines.
Surge Protection
ADAM-4510I and 4520I offer internal surge protec-
tion on their data lines. Internal high speed transient
suppressors on each data line protect the modules
from dangerous voltages levels or spikes.
Tough Industrial Design
You can power ADAM-4510I and ADAM-4520
with any unregulated power source between +10
and +48 VDC. Their industrial-grade plastic shells
can be mounted on a DIN-rail, panel or in a piggy-
backed stack. You make signal connections through
plug-in screw terminal blocks, guaranteeing easy
installation, maintenance and modification.
