Page 5: Cl4490 Rf Transceiver
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. -

Page 10: Table 1 – Dte, Dce And Null Modem Signal Definitions
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. -
Page 11: Rs-232
CL4490 User’s Manual 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. -
Page 12: Rs-485 (2-Wire Half Duplex)
RF, it will transmit the packet over the RS-485 bus. Note: When using RS-485 (2-wire Half Duplex), a RS-485 to RS-232 converter is required to configure the unit. AeroComm recommends a B&B Electronics 4WSD9R converter to translate RS-485 to RS-232. -
Page 13: Hardware Flow Control
CL4490 User’s Manual 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. -
Page 14: Network Topologies
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. -

CL4490 User’s Manual 4. CL4490/CN4490 Configuration Utility Software AeroComm provides the easy to use CL4490/CN4490 Utility Software for programming the CL4490/CN4490. The GUI based software does not require any hardware configuration and works by itself. The software is compatible with Microsoft® Windows 95, 98, 2000, Me, NT and XP. -

The RF baud rate is fixed at 76.8 Kbps and is independent of the Interface Baud Rate. The default baud rate setting is 57600 bps unless the units have been pre-configured by AeroComm. The Interface Baud Rate setting of the CL4490 must match the Baud Rate setting of its host device. - Page 17 Destination Address: The MAC Address of the remote CL4490 in a Point-to-Point network. Used to optimize Point-to-Point communications by utilizing RF Acknowledgement. Firmware Version: Displays the CL4490’s firmware version. MAC Address: A unique 6 Byte, IEEE 802.3 Ethernet address assigned by AeroComm to each CL4490. 4.1.1.2 Optional Settings Data Encryption: Enables the Data Encryption Key.
- Page 18 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.
