SuperSCREAMER™ - 900MHz Multi-Protocol RF Modem

Ewave's SuperSCREAMER™ RF Modem is our flagship modem. Firmware features allow the user to select from five different RF protocols. This is a feature-rich modem that gives the user total control over such options as hardware handshake signals (RTS/CTS), generation of Break conditions, automatic transparent retry and acknowledge protocols to insure that data gets through in noisy RF enviroments.

Features & Benefits
  • Protocols Supported:
  • Protocols are dynamically selectable at any time.
  • Default protocol may be saved in Modem's EEPROM.

  • Standard Features of the Ewave RF Modem family, which include:

    Common to All Modem Models:

    • Ewave's RF10K DualDSP modem core
    • FCC certified; no user license required.
    • Full duplex, allowing simultaneous transmission and reception of data.
    • Transparent, simple operation: Looks like a serial cable to your application.
    • Dynamic packetization of data, providing low latency while maintaining high throughput.
    • Commands may be sent on-the-fly (e.g., Transmit Power On/Off, Channel) or modem may be configured once and "locked" in the Data state for maximum transparency to your application.
    • Integrated antenna.
    • Operation from regulated 5V or unregulated ~7.2-10VDC (in which case the modem can supply 5V to another device); 3.3V also available.
    • Non-volatile (EEPROM) storage of user parameters (e.g., Channel, Baud Rate).
    • Status LEDs indicating Transmit and Receive Activity, Transmitter Power On/Off and Command/Data Mode.
    • 9600 bps sustained data throughput (higher data rate available if transparent CRC generation and checking is disabled).

    Optional (Varies by Modem Model):

    • 1, 5 or 40 user-selectable channels.
    • Programmable baud rates, up to 38.4K.
    • Transparent protection from errors and interference via 16-bit CRC (Cyclic Redundancy Code).
    • Packetization configurable via software parameters: Maximum Packet-Size Threshold and Next-Byte Wait Time.
    • High data reliability via transparent, automatic Retry/Acknowledge.
    • Support for RS232 "Break" conditions and RTS/CTS control signals.

Voltage (VDC) 5.0 regulated or 7.2-10 unreg.
Current (A) 140 mA, TX power ON
Current (A) 100 mA, TX power OFF
Sustained Data Rate 9600 baud or 1071 bytes/sec
Burst Data Rate 38.4 K baud
Range 300 feet typical
Frequency (MHz) 902-928
