    ... Reliable communication up to 115.2Kbps 1.1 Overview The CL4490 uses Frequency Hopping Spread Spectrum modulation, where the units “hop” from frequency to frequency many times per second using a specific hop pattern applied to all the transceivers in the same network. A distinct hopping pattern is provided for each Channel Number, thereby allowing multiple networks to co-exist in the same area without interference ...

    ... 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 nodes may be connected ...

    ... 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 DTE with another DTE, a null modem (or a Crossover) cable is required ...

    ... 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 ...

    ... The nodes will have unique addresses and can send addressed packets to specific nodes. Because the bus is half duplex, no two nodes should try to talk at the same time. The CL4490 does not have a RS-485 address, therefore, it will transmit all RS-485 traffic over the RF. Conversely, as soon as a CL4490 receives a packet over the RF, it will transmit the packet over the RS-485 bus ...

    ... Flow control allows the slower device to tell the faster device to pause and resume data transmission. (Flow control CTS and RTS are used by the CL4490 and its Host, locally – NOT over the air. Therefore, one CL4490 cannot tell the other to slow down or speed mentioned above in the paragraph.) When the RTS Enable option is selected on the Configuration Utility, the transceivers use hardware flow control to regulate data flow ...

    ... 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 wireless bridge, a point-to-point link replaces a single communications cable. A point-to-point link might be used to connect a PLC to a remote monitoring station ...
