CE/FCC Notification
ADAM-4510, ADAM-4510S and ADAM-4520 devel-
oped 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 dam-
aged by ESD, we strongly recommend that the use of
CE-compliant industrial enclosure products
Most industrial computer systems come with RS-232
serial ports. Though widely accepted, RS-232 has lim-
ited transmission speed, range and networking capa-
bilities. The RS-422 and RS-485 standards overcome
these limitations by using differential voltage lines for
data and control signals.
ADAM-4520 is a isolated converter for systems origi-
nally equipped with RS-232. It transparently converts
RS-232 signals into isolated RS-422 or RS-485 sig-
nals. You don't need to change your PC's hardware or
your software. The ADAM-4520 lets you easily build
an industrial grade, long distance communication sys-
tem with standard PC hardware.
The ADAM-4510 and ADAM-4510S repeaters simply
amplify, or boost, existing RS-485 signals to enable
them to cover longer distances. They extend the com-
munication distance by 4000 ft (1200 m) or extends
the number of connected nodes by 32.
Intelligent RS-485 Control
The RS-485 standard supports half-duplex communi-
cation. This means that just two wires are needed to
both transmit and receive data. Handshaking signals
(such as RTS, Request To Send) are normally used to
control the direction of the data flow. A special I/O cir-
cuit in ADAM-4510, ADAM-4510S, and ADAM-4520
automatically senses the direction of the data flow and
switches the transmission direction. No handshaking
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. Software written
for half-duplex RS-232 works without modification.
Isolation (ADAM-4510S/4520 only)

isolation to protect the host computer
from ground loops and destructive voltage spikes on
the RS-485 data lines.
Surge Protection (RS-485 only)
ADAM-4510/4510S and ADAM-4520 offer internal
surge-protection 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-4510, ADAM-4510S and
ADAM-4520 with any unregulated power source

. Their industrial-grade
plastic shells can be mounted on a DIN-rail, panel or in
a piggybacked stack. You make signal connections
through plug-in screw terminal blocks, guaranteeing
easy installation, maintenance and modification
