CL4490 User’s Manual 1. CL4490 RF Transceiver The CL4490 transceiver is a Frequency-Hopping Spread Spectrum (FHSS) radio designed for license-free operation in the 900MHz ISM band. Out-of-the box, the radio sustains a standard asynchronous serial data stream between two or more radios. Housed in a compact and rugged die-cast enclosure, the radio is equipped to replace thousands of meters of serial cable with its wireless link. The radio features an RS-232 or RS-485 interface for integrat

CL4490 User’s Manual 1.3 CL4490 Interface The CL4490 supports RS-232/RS-485 (2-wire Half Duplex) protocols. By definition, RS-485 protocol can tolerate high noise and push signals over long cable lengths. When using cables, RS-485 will communicate as far as 4000feet (1200m) and offer multi-drop capability where up to 32 nodes may be connected. RS-232 cables are suitable for distances less than 100 feet (30.5m). AeroComm wireless solutions are not subject to the cabling restrictions f

CL4490 User’s Manual 2. Interfacing Protocol The CL4490 is a DCE (Data Communications Equipment). A DCE can be interfaced to a DTE using a straight through serial cable (the serial cable provided with the CL4490 is a straight through cable). Typically, PC’s are defined as a DTE and peripherals are defined as DCE. To interface a DCE with another DCE, or a DTE with another DTE, a null modem (or a Crossover) cable is required. The null modem simply swaps pins to convert a DCE to a DTE a

CL4490 User’s Manual 1.4 RS-232 RS-232 is a single ended data transmission protocol. The RS-232 signals are represented by voltage levels with respect to a system common (power / logic ground). The "idle" state (MARK) has the signal level negative with respect to common, and the "active" state (SPACE) has the signal level positive with respect to common. RS-232 has numerous handshaking lines (primarily used with modems), and also specifies a communications protocol. Figure 5- RS-232 M

CL4490 User’s Manual 1.6 Hardware Flow Control Flow control refers to the control of data flow between the host and the CL4490. It is the method used to handle data in the transmit/receive buffer of the CL4490 interface, and determines how data flow between the host and the CL4490 is throttled. Often in serial communication, one device is capable of sending data much faster than the other can receive. Flow control allows the slower device to tell the faster device to pause and resume data

CL4490 User’s Manual 3. Network Topologies Topology refers to the shape of a network, or the network's layout. How different nodes in a network are connected to each other and how they communicate, is determined by the network's topology. The CL4490s support a Point-to-Point and a Point-to-Multipoint network topology. 3.1 Point-to-Point A point-to-point system is a simple arrangement consisting of just two CL4490s - a Server and a Client. Sometimes referred to as a wireless bridge,

CL4490 User’s Manual Max Transmit Retries (For Clients and Servers in Point-to-Point networks only): This value represents the maximum number of times a particular data packet will be transmitted unsuccessfully, or without an acknowledgement, before the CL4490 discards the packet. The default value is 16 attempts. If communication is lost and the Client’s Link LED is on, try increasing this value in small increments until communication is reestablished. Note: This value is always as

CL4490 User’s Manual Full Duplex: This mode restricts Client radios to transmitting on odd numbered frequency hop bins and the Server to even numbered frequency hop bins. Though the RF hardware is still technically half duplex, it makes the transceiver seem full duplex. This can cause overall throughputs to be cut in half. Note: All transceivers on the same network must have the same setting for Full Duplex. Modem Mode: Full modem handshaking is supported by the transceivers when M
