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 specifi cally developed for industrial applications to transmit and receive data at high rates over long distances.

Only two wires are needed for transmitting and receiving data. Handshaking signals such as RTS Two-wire Communication (Request to Send) normally control the direction of the data fl ow. A special I/O circuit in the The ADAM-5000/485 and ADAM-5000E systems use a single twisted pair of wires to ADAM-4510 and ADAM-4520 senses the data fl ow direction and automatically switches transmit and receive data. Special circuitry ensures clean, reliable communication and the transmission direction, making handshaking signals unnecessary. The RS-485 bus suppresses communication line noise. This reduces overall network cost by simplifying control is completely transparent to the user. installation and minimizing the number of cables, connectors, communication repeaters and fi lters required. Built-in RS-232 Communication ADAM-5000/485 and ADAM-5000E systems provide up to 64/128 I/O points and an Surge Protection RS-232 port. A host PC can be locally connected to the system to control and monitor High speed transient suppressors protect the system from dangerous voltage surges or simple applications, thereby facilitating local troubleshooting. power spikes. ASCII-based Protocol Network Expansion ADAM-5000 commands are issued in printable ASCII-based format. ADAM applications The ADAM-4510 repeater simply amplifi es or boosts existing signals, enabling them to can be written in any high-level language that supports ASCII string functions, such as travel over longer distances. C, Pascal or BASIC. ASCII support means you can use virtually any computer to manage Each repeater allows you to add up to 32 ADAM-5000 units to your network, extending your ADAM network. 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. 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 modifi cation. The ADAM-4520 helps you build an industrial grade, long distance communication system with standard PC hardware.
