Introduction
The ADAM-5000/485 and ADAM-5000E systems use the EIA RS-485 communication protocol. This is the industry's most widely used, balanced, bidirectional transmission line
standard. The RS-485 was specifically developed for industrial applications to transmit and receive data at high rates over long distances.

Intelligent RS-485 Data Flow Control
Two-wire Communication
The ADAM-5000/485 and ADAM-5000E systems use a single twisted pair of wires to
transmit and receive data. Special circuitry ensures clean, reliable communication and
suppresses communication line noise. This reduces overall network cost by simplifying
installation and minimizing the number of cables, connectors, communication repeaters
and filters required.
Surge Protection
High-speed transient suppressors protect the system from dangerous voltage surges
or power spikes.
The RS-485 communication protocol will support half-duplex communication. Only two
wires are needed for transmitting and receiving data. Handshaking signals such as RTS
(Request to Send) normally control the direction of the data flow. A special I/O circuit in the
ADAM-4510 and ADAM-4520 senses the data flow direction and automatically switches
the transmission direction, making handshaking signals unnecessary. The RS-485 bus
control is completely transparent to the user.
Built-in RS-232 Communication
ADAM-5000/485 and ADAM-5000E systems provide up to 64/128 I/O points and an
RS-232 port. A host PC can be locally connected to the system to control and monitor
simple applications, thereby facilitating local troubleshooting.
ASCII-based Protocol
Network Expansion
The ADAM-4510 repeater simply amplifies or boosts existing signals, enabling them to
travel over longer distances.
Each repeater allows you to add up to 32 ADAM-5000 units to your network, extending
the network by another 4000 feet (1.2 km). Up to 256 ADAM-5000/485, ADAM-5000E
units can be connected to a single RS-485 network.
ADAM-5000 commands are issued in printable ASCII-based format. ADAM applications
can be written in any high-level language that supports ASCII string functions, such as
C, Pascal or BASIC. ASCII support means you can use virtually any computer to manage
your ADAM network.
RS-232 to RS-485 Conversion
RS-232 serial ports are standard with most industrial computer systems. Though widely
accepted, RS-232 has limited transmission speed, range and networking capabilities.
The RS-485 standard overcomes these limitations by using differential voltage lines for
data and control signals.
The ADAM-4520's isolated converter lets you take advantage of an RS-485 on an RS-232
system by converting RS-232 signals to RS-485 signals. Software written for half-duplex
RS-232 may also be used without modification.
The ADAM-4520 helps you build an industrial grade, long distance communication
system with standard PC hardware.
