AIM Advanced Instrumentation Module

The AIM replaces the UWINSTRU Underwater Attitude Sensors, and expands greatly upon the capabilities of this long-running instrumentation design.

The AIM Advanced Instrumentation Module is a compact, scalable general-purpose data acquisition system. Designed primarily for installation in tethered remote sensing systems, this module is ideal for any application requiring high quality data acquisition in a small footprint.

With up to 24-bit accuracy of measurement, on-board conditioning circuitry for RTDs and Wheatstone Bridge type pressure sensors, in-situ programmable digital calibration, access to all digital and analog signals via connectors, firmware upgradability and a powerful suite of communications and sensor interface software, the AIM module is an easily customizable data acquisition system.

Features:

• 24-bit Sigma-Delta ADC/16-bit DAC, 8/2 channel multiplexed
• 8052-based 22 MHz microcontroller
• 128 kB SRAM + 32 kB flash RAM for firmware and calibration storage
• On-board CPLD for future expansion (40% of macrocells unused and available for custom use)
• Integrated low profile stacking ports for custom expansion boards
• Integrated port for internal digital compass and tilt sensor
• NMEA 0183 communications via 2-wire RS-485 with bi-directional capabilities

The AIM Advanced Instrumentation Module is currently available with additional peripherals to follow in the future.

The subsea housing for the system can be made from either hard-anodized 6061-T6 aluminum or Grade 2 titanium, and is rated to up to 2000m depth, or greater with titanium, depending on the sensor fitted. SEACON Brantner Micro-MiniCon connectors are fitted as standard, but other subsea connectors may be custom fitted.

Future models:

Expansion boards including:
Smartmedia Memory Card adapter
Battery charger and power supply system
Additional sensor channel breakout board
3-D Heading/Pitch/Roll sensors
