The MLCPU-1 module contains the microprocessor, memory, power supplies, GPDI input circuitry, alarm output circuitry, User push buttons and status indicators. Various components in this module are identified in Figure 2... -3. This module is required in all OMP-MODL systems.

User Interface Indicators and Buttons

An array of LED indicators and buttons are available at one end of the MLCPU-1. Identification and function follows:

Main Power Switch:

A small recessed toggle switch controls the power to the logger. Using a pencil or other small object, flip the switch side to side to turn power ON/OFF. Upon turning power ON, after a short delay, the Feedback LED (see following) will blink 5 times indicating that the unit has sequenced through a power-up reset and is operative, ready to accept commands.
