    S E R I A L I N T E R F A C E The CL4490 supports RS232, RS485, and RS422 protocols. Aerocomm wireless solutions are not subject to the cabling restrictions for distance, and either interface is available when ordering.
  • Page 8 C H A P T E R 3 - S E R I A L I N T E R F A C E R S 2 3 2 RS232 is a single-ended data transmission protocol. The RS232 signals are represented by voltage levels with respect to a system common (power/logic ground).

    Each network should consist of only one Server and there should never be two servers on the same RF Channel number in the same coverage area as the interference between the two servers will severely hinder RF communications. For those applications requiring collocated servers, Aerocomm recommends using the Sync-to-Channel feature which is further explained in the Sync-to-Channel Appendix.
  • Page 13 C H A P T E R 4 - T H E O R Y O F O P E R A T I O N R E C E I V E M O D E When a transceiver is not in Transmit or Command mode, it will be in Receive Mode listening for data. While in Receive Mode, subsequent data of up to 80 bytes can be received every hop (20 ms).

    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-PRO must match the Baud Rate setting of its host device.

  • Page 17 Note: The Show Defaults button can be used to display the default Radio settings. DESIGN TIP The Aerocomm Configuration utility automatically programs the mode (point-to-point or point- to-multipoint) based on the radio’s current settings: If the Destination Address field is set to any value other than FF FF FF FF FF FF, the radio will send data only to the radio whose MAC matches that specified in the Destination Address field (point-to-point).
