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 CEcompliant industrial enclosure products.
Overview
Most industrial computer systems come with RS232 serial ports. Though widely accepted, RS-232
has limited transmission speed, range and networking capabilities. RS-422 and RS-485 standards overcome these limitations by using differential voltage
lines for data and control signals.
ADAM-4520I is isolated converter for systems originally equipped with RS-232. It transparently converts RS-232 signals into isolated RS-422 or RS485 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 communication 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 communication. 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 circuit in ADAM-4510I and ADAM-4520I
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 can work without modification.
Isolation
ADAM-4510I and ADAM-4520I's opto-isolators
provide 3000 VDC isolation to protect the host computer from ground loops and destructive voltage
spikes on the RS-485 data lines.
Surge Protection
ADAM-4510I and 4520I 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-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 piggybacked stack. You make signal connections through
plug-in screw terminal blocks, guaranteeing easy
installation, maintenance and modification.

Switch Settings
Switch Description
DIP switches in the ADAM converter and repeater
modules set the data format (number of bits) and baud
rate for the ADAM network. You can configure the
other modules in the network via software commands.
Your program and the PC's serial port should match the
settings of the converter and repeater modules.
SW1
Switch 1 controls the data format. Data can be 9, 10, 11
or 12 bits. The factory default is 10 bits: one start bit,
eight data bits, no parity bit and one stop bit.
When using the converter in combination with other
ADAM modules, do not change the default setting as
ADAM modules have a fixed data format of ten data
bits. The option of changing to 9, 11 or 12 bits is for use
with other modules (other than ADAM modules) that
have different data formats. When you change the data
format, you will have to change the data format settings
on all the other modules in the network.
SW2
Switch 2 sets the baud rate. The options range from
1200 bps to 115.2 kbps. The factory default is 9600 bps.
Be aware that when you change the baud rate, you have
to change the baud rate for all the connected modules
accordingly. If the RS-422 mode is ON, the baud rate
doesn't need to be set.
SW3
Switch 3 sets the mode. When the mode is set “Nor-
mal”, the baud rate and data format will use SW1 and
SW2 setting. When the mode is set “Auto Baud Rate
with Noise Reduction”, the baud rate and data format
will be set automatically. This mode also help reduce
the noise.
Note: There is only one ADAM-4510I or ADAM4520I module can be set in “Auto Baud Rate with
Noise Reduction” mode in singe RS-485 network.
