General/Isolated RS-422/485 Repeater ADAM-4510/4510S Isolated/ General RS-232 to 422/485 Converter /4520/4522 Features • Automatic internal RS-485 bus supervision • No external flow control signals required for RS-485 • 3000 VDC isolation protection (ADAM-4510S/4520) • Transient suppression on RS-485 data lines • Speeds up to 115.2 Kbps • Networking up to 4000 feet • Reserved space for termination resistors • Power and data flow indicator for troubleshooting • Power requirement: +10 to +30 VDC • Mounts easily on a DIN-rail or panel Introduction • Accessories (supplied): ABS DIN-rail mounting adapter, Most industrial computer systems come with standard RS-232 serial ports. Though widely accepted, RS-232 has limited SECC panel mounting bracket transmission speed, range, and networking capabilities. The RS-422 • Plug-in screw terminal wiring: Accepts AWG 1- #12 or 6 and RS-485 standards overcome these limitations by using 2 2- #14 ~ #22 (0.5 to 2.5 mm ) wires differential voltage lines for data and control signals. The • Operating temperature: -10 to 70° C (14 to 158° F) ADAM-4520/4522 converter lets you take advantage of RS-422 and RS-485 on systems originally equipped with RS-232. It transparently • Dimensions: 60 mm x 120 mm (2.36" x 4.41") converts RS-232 signals into isolated RS-422 or RS-485 signals. You do not need to change your PC's hardware or your software. ADAM-4510/4510S The ADAM-4520/4522 lets you easily build an industrial grade, long • Transmission speed (bps): 1200, 2400, 4800, 9600, distance communication system with standard PC hardware. 19.2 K, 38.4 K, 57.6 K, 115.2 K (switchable) The ADAM-4510/4510S repeater simply amplifies, or boosts, existing • Isolation voltage: 3000 VDC (ADAM-4510S only) RS-422/485 signals to enable them to cover longer distances. It • RS-422/RS-485 interface connector: Plug-in screw terminal extends the communication distance by 4000 ft. (1200 m) or increases the maximum number of connected nodes by 32. • Power consumption: 1.4 W An RS-485 network with Automatic Data Flow Control using ADAM-4520/4522 RS-232 Software • Transmission speed (bps): 1200, 2400, 4800, 9600, The RS-485 standard supports half-duplex communication. This 19.2 K, 38.4 K, 57.6 K 115.2 K, RTS control and RS-422 mode means that a single pair of wires is used to both transmit and receive (switchable) data. Handshaking signals such as RTS (Request To Send) are • Isolation voltage: 3000 VDC (ADAM-4520 only) normally used to control the direction of the data flow. A special I/O circuit in the ADAM-4510/4510S and ADAM-4520/4522 automatically • RS-232 interface connector: Female DB-9 senses the direction of the data flow and switches the transmission • RS-422/RS-485 interface connector: Plug-in screw terminal direction. No handshaking signals are necessary—you can build an • Power consumption: 1.2 W 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.
