As shown in the schematic in Figure 3-2, the CTD, ACM, INDUCTIVE MODEM,
FLUOROMETER and TURBIDITY sensors each have dedicated switched power connectors. The
CTD CONNECTOR is hardware configured to support either the FSI or the SeaBird CTD. The
SPARE CONNECTOR has an RS-232 Electronic Industries Alliance (EIA) or a 5v
Complementary Metal Oxide Semiconductor (CMOS), a dedicated switched power output, three
analog inputs, two digital outputs and a user interrupt input. The
SPARE SERIAL PORT has an
RS-232 (EIA or 5VCMOS) and a dedicated switched power output. The Rev D board supports
two full size batteries.
Figure 3-2: MMP Rev D Electronics Schematic
The Rev D board has a single CPLD (Complex Programmable Logic Device) that can be
programmed through the
JTAG CONNECTOR. A temperature-compensated crystal oscillator
(TCXO) provides highly reliable time-keeping in the system watchdog clock.
The top circuit board in the controller is a Persistor CF (Compact Flash) memory
expansion board that holds a 512MB compact flash card.
NOTE
McLane uses a flashcard certified by Persistor Instruments, Inc. (www.persistor.com).
