ADAM-4510/4510S
RS-422/485 Repeater
Introduction
Introduction
Most industrial computer systems come as standard
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 overcome these limitations by using
differential voltage lines for data and control signals.
The ADAM-4520 isolated converter lets you take
advantage of RS-422 and RS-485 on 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-4520 lets you
easily build an industrial grade, long distance
communication system with standard PC hardware.
The ADAM-4510/4510S repeater simply amplifies, or
boosts, existing RS-485 signals to enable them to
cover longer distances. It extends the communication
distance by 4000 ft (1200 m) or extends the number of
connected nodes by 32.

Isolated RS-232 to RS-422/485
Converter
Tough industrial design
You can power the ADAM-4510/4510S and ADAM4520 with any unregulated power source between +10
and +30 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

Features
o Automatic internal RS-485 bus supervision
o No external flow control signals required for RS485
o Minimum 3000 V DC isolation protection
(ADAM-4510S/4520)
o Transient suppression on RS-485 data lines
o Baudrate up to 115.2 Kbps

Intelligent RS-485 control

o Networking up to 4000 feet

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 the ADAM-4510/4510S and
ADAM-4520 automatically senses the direction of the
data flow and switches the transmission direction. No
handshaking signals are necessary--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.

o Reserved space for termination resistors
o Power and data flow indicator for troubleshooting
o Power requirement: +10 to +30 VDC
o Mounts easily on DIN-rail or panel

Specifications
Common
o Power requirement:
Unregulated +10 to +30 VDC with protection from

Isolation (ADAM-4510S/4520 only)

o Case: ABS with captive mounting hardware

The ADAM-4510S/4520's Opto-isolators provide 3000
VDC of isolation to protect the host computer from
ground loops and destructive voltage spikes on the
RS-485 data lines.

o Accessories (Supplied):
NYLON DIN-rail Mounting Adapter
SECC Panel Mounting Bracket
o Plug-in screw terminal wiring:
Accepts AWG 1-#12 to #22 (0.5 to 2.5 mm) wires

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.

As you unpack the modules, check them for signs of
shipping damage (damaged box, scratches, dents,
etc.). If it is damaged or fails to meet our specifications, notify our service department or your local sales
representative immediately. Also, call the carrier
immediately and retain the shipping carton and
packing material for inspection by the carrier. We will
then make arrangements to repair or replace the unit.

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.

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. 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.

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.

For the ease of use in industrial environments the
ADAM modules are designed to accept industry
standard +24 VDC unregulated power. Operation is
guaranteed when using any power supply between
+10 and +30 VDC. Power ripples must be limited to 5 V
peak to peak while the voltage in all cases must be
maintained between +10 and +30 VDC. 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 thicker wire to limit the line
voltage drop. In addition to serious voltage drops, long
voltage lines can also cause interference with
communication wires.

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. We advise that the following
