The Carousel Auto-Fire Module (AFM) allows the Carousel Water Sampler (SBE 32, 32C, or 32SC) to operate autonomously on non-conducting cables. The AFM includes a microprocessor, solid-state memory, RS-232 interface, and battery power that supply the operating voltage, logic, and control commands to operate the Carousel.
When used without a CTD, the AFM fires bottles at pre-defined elapsed times after receipt of the Arm command. The depth at which samples are taken can be determined (approximately) by monitoring cable length pay out and elapsed time. The AFM records bottle number, date and time, and fire confirmation for each bottle fired. At the end of a cast, the bottle data (.afm) file is uploaded from the AFM.
When used with a CTD (SBE 19, 19plus, or 19plus V2 SeaCAT Profiler, or SBE 25 or 25plus Sealogger) or SBE 50 Pressure Sensor, the AFM:
Setup and data upload are performed (without opening the housing) with our SeatermAF terminal program. At the end of a cast, CTD data is uploaded from the CTD (through the AFM) and bottle data is uploaded from the AFM. SBE Data Processing’s Data Conversion module converts the raw CTD data and creates a .cnv CTD data file and .ros bottle data file.
Firmware upgrades can be downloaded through the communications port by the user, without opening the housing.
The AFM has an anodized aluminum housing rated to 6800 meters (22,300 feet). Bulkhead connectors for the CTD, Carousel, and Data I/O (RS-232) are mounted on the housing end cap. The AFM is typically installed on the Carousel, with the same mounting bracket used to mount a SeaCAT, and hangs vertically between the upper and lower adapter plates.
The AFM is powered by 9 alkaline D-size cells, which provide approximately 60 hours of operation. Optionally, the AFM can be powered by rechargeable NiMH batteries. Battery endurance is predominantly a function of the amount of time the AFM is powered and armed; the number of bottles fired has little impact.
The AFM is supplied with a powerful Win 2000/XP software package, Seasoft© V2, which includes:
64K byte static RAM.
Memory space for 1 cast (24 bottles maximum). AFM memory records for each bottle fired:
-- (if used with a CTD) Bottle sequence and number, date and time, firing confirmation, battery voltage, scan number of first of 5 CTD scans, and 5 scans of CTD data
-- (if used without a CTD) Bottle sequence and number, date and time, firing confirmation, and battery voltage
