ADL Sentry

ADL Sentry is an advanced, high speed, wireless data link built to survive the rigors of precise positioning and environmental monitoring applications. This sophisticated 0.1-4.0 Watt radio modem utilizes Pacific Crest’s next generation on Advanced Data Link (ADL) technology while remaining backward compatible with existing Pacific Crest, Trimble and other products. The ADL Sentry is ideal for remote sensing, machine control, and environmental monitoring applications. For the most rugged and reliable digital data link, go with the new standard in wireless communications – ADL Sentry.

Key Features

  • Heavy-Duty Construction:
    All metal construction for the ultimate in impact and EMI resistance
  • Environmentally sealed:
    The radio and both the antenna and data/power ports are environmentally sealed to IP67 standard
    Screw-on connectors ensure even the cables stay watertight
  • High Over-the-Air Link Rate:
    19,200 bps (both GMSK and 4FSK) Higher data rates allow shorter transmission times for increased battery life
  • Configurable Transmit Power:
    0.1-2 W for longer battery life 4.0 W for longer range (where permitted)
  • Advanced 40 MHz Bandwidth:
    390-430 and 430-470 MHz models Advanced Data Link design for high performance over the entire band
  • Software-Derived Channel Bandwidth:
    All models support both 12.5 and 25 kHz channel spacing
