manual abstract


CL4424 transceivers operate in a Point-to-Point or Point-to-Multipoint, Client-Server or Peer-to- Peer architecture. One transceiver is configured as a Server and there can be one or many Clients. To establish synchronization between transceivers, the Server emits a beacon. Upon detecting a beacon, a Client transceiver informs its Host and a RF link is established. CL4424s implement a proprietary communication protocol to provide secure data transmissions. Using FHSS technology, the data remains reliable over long distances. The use of license free frequency bands ensures that the units are ready to use with no further certification requirements. Each unit is small and easily portable for use in mobile and temporary settings as well as for fixed installations. The CL4424 configuration software enables custom configurations based on unique application requirements. CL4424 User’s Manual 1.2 CL4424 Specification CL4424 TRANSCEIVER PERFORMANCE Output power (w/ 3dBi antenna) 100mW Transmission range Up to 500 feet (450m) indoors; Up to 1 mile (1.6 km) line-of-sight Data rate Up to 115.2 Kbps RF Data Rate 576kbps fixed Receiver Sensitivity -100dBm typical @ 576kbps RF Data Rate Power Consumption (@ 12 Vdc) 102mA (50% Transmit/Receive duty cycle) Configuration software Easy-to-use Windows based software NETWORKING AND SECURITY Frequency band, RF Technology 2402 – 2478MHz, FHSS Supported Network Topologies Point-to-Point, Point-to-Multipoint Channels 40 US/Canada/Europe, 20 France Security One byte System ID ANTENNA RF Connector RPSMA Jack Type 1/2 Wave Dipole ELECTRICAL Electrical requirements Line voltage 100 – 120V (240V outside US); Power supply 6-foot cable, AC power connector ENVIRONMENTAL Environmental conditions Operating temperature -40° to +80°C; 10% to 90% humidity (non-condensing) PHYSICAL Dimensions 4.4 x 2.7 x 1.4 inches Weight 6 oz (170 g) Serial Connector DB-9 Male (RS-232), Terminal Block (RS-485) Power Jack Dimensions 0.100” diameter pin with 0.250” diameter opening. Center positive. Serial Cord length 6 feet (183 cm) CL4424 User’s Manual 1.3 CL4424 Interface CL4424 transceivers support RS-232/ RS-485 (2-wire Half Duplex) protocols. In a cabled environment, the RS-485 protocol can tolerate high noise and push signals over long cable lengths. RS-485 cabling can also communicate as far as 4000 feet (1200m) and offer multi-drop capability where up to 32 nodes can be connected. RS-232 cabling is suitable for distances less than 100 feet (30.5m) and only supports point-to-point communications. CL4424 transceivers offer performance improvements over a standard cabled link. Distance and multipoint communications are greatly enhanced. A selection of RS-232/RS-485 can be made when ordering the CL4424s. Figure 1- RS-232/RS-485 CL4424 Front View RPSMA Antenna Connector Status LEDs Pwr Link Rx Tx CL4424 Status LEDs Description Pwr Green On indicates that the unit is powered up. Link Red On indicates the Client unit(s) and Server unit are in range of one another. Link LED remains activated on Server units. Client units activate the Link LED when in range of the Server unit. Rx Green When flashing, LED indicates CL4424 unit is receiving data. Tx Red When and flashing, LED indicates CL4424 unit is sending data.

Interfacing Protocol The CL4424 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 CL4424 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 and vice-versa. A null modem cable can be provided with the CL4424 on request. The CL4424 transceivers support the following interface protocols • RS-232 • RS-485 (2-wire) Half Duplex Table 1 – DTE, DCE and Null Modem S...
