MaxStream 9XStream Wireless Module


View larger image

The 9XStream is a frequency-hopping wireless module that allows wireless communication between equipment using a standard asynchronous serial data stream.

The 9XStream operates within its respective ISM Band and is approved by the FCC under Part 15 of FCC Rules and Regulations. A regulated 5-volt supply is required for operation.

The 9XStream module requires no knowledge of radio frequency (RF) design. It interfaces to any UART or PC Serial Port using the MaxStream interface board and has been developed with a small form-factor for ease of integration. The data transfer performance of the 9XStream has been enhanced with proprietary technology from MaxStream and requires no additional licensing or FCC approval.

The half-duplex transmission of the 9XStream can sustain a continuous data stream at the specified data rate. The 9XStream has been engineered for use with the following applications (among others):

  • Supervisory Control and Data Acquisition (SCADA)
  • Remote Meter Reading
  • Home Automation
  • Security
  • Instrument Monitoring
  • Point of Sale Systems (POS)
FEATURES:
  • Frequency-Hopping Spread Spectrum (FHSS) technology
  • Noise and interference resistance
  • Enhanced sensitivity and range
  • Multiple low-power modes (down to 1µA)
  • Standard serial digital interface connection
  • Built-in networking and addressing
  • Simple AT command interface
  • 9600 and 19200 baud transfer rates available
  • Packet retries and acknowledgments
The 9XStream comes with the following models:
  • 9XStream 900MHz 9600bps (for Bulkhead with 6" Pigtail MMCX Antenna)
  • 9XStream 900MHz 9600bps (for Non-Bulkhead Articulating RPSMA Antenna)
  • 9XStream 900MHz 19200bps (for Bulkhead with 6" Pigtail MMCX Antenna)
  • 9XStream 900MHz 19200bps (for Non-Bulkhead Articulating RPSMA Antenna)
