1 ADAM-4510/4510S/4520 Startup Manual

March 2005.

Most industrial computer systems come with RS-232
serial ports. Though widely accepted, RS-232 has lim­ited transmission speed, range and networking capa­bilities. The RS-422 and RS-485 standards ov ercome
these limitations by using differential voltage lines for
data and control signals.

ADAM-4520 is a isolated converter for systems origi­nally equipped with RS-232. It transparently converts
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-4520 lets you easily build
an industrial grade, long distance communication sys­tem with standard PC hardware.

The ADAM-4510 and ADAM-4510S repeaters simply
amplify, or boost, existing RS-485 signals to enab le
them to cover longer distances. They extend the com­munication 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 communi­cation. This means that just two wires are needed to
both transmit and receive data. Handshaking signals
(such as RTS, Request To S end) are normally used to
control the direction of the data flow. A special I/O cir­cuit 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 w orks wit hout modification.

Isolation (ADAM-4510S/4520 only)

ADAM-4510S and ADAM-4520's Opto-isolators pro­vide 3000 V

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 pr ot ect
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
between +10 and +30 V

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 Descriptions

DIP switches in the ADAM converter and repeater mod­ules set the data format (number of bits ) and baudrate 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) tha t have dif­ferent data formats. Should you change the data format,
be aware that you will have to change the data format set­tings on all the other modules in the network.

SW2

Switch 2 sets the baudrate. The options range from 1200
bps to 115.2 kbps. The factory default is 9600 bps. Be
aware that when you change the baudrate, you have to
change the baudrate for all the connected modules
accordingly. If the RS-422 mode is ON, the baudrate
doesn't need to be set.

Default Settings

Both Modules are not addressable by the host computer,
the baud rate and data f ormat must be set using SW1 and
SW2 located inside the module. The default settings are:

Power Supply

For easy use in industrial environments, the ADAM mod­ules are designed to accept industry standard +24 V

unregulated power. Operation is guaranteed when using
any power supply between +10 and +30 V

ples must be limited to 5 V peak to peak while the voltage
in all cases must be maintained between +10 and +30

. All power supply specifications are referenced at

module connector.
The power cables should be selected according to the

number of modules connected and the length of the
power lines. When using a network with long cables, we
advise the use of thick er wire to limit the lin e v oltage drop.
In addition to serious voltage drops, long v oltage lines can
also cause interference with communication wires.

Communication Wiring

We recommend that shielded-twisted-pair cables that
comply with the EIA RS-485 standard be used with the
ADAM network to reduce interference. Only one set of
twisted-pair cables is required to transmit both data and
RTS signals. W e ad vi se that th e following standard colors
(as indicated on the modules) be used for the communica­tion lines:

Basic configuration hook-up.

Before placing a module in an existing network, the mod­ule should be properly configured. The two following dia­grams show typical layouts for both modules.
