ECX’s programmable information and control systems are engineered to perform all the electrical functions required in an emergency, recreational, and industrial vehicles in a manner that is cost effective, flexible, and reliable.

The system is built around a multiplexed data highway, as shown under the heading Block Diagram. This Data Highway links the various modules that make up the control systems.

Modules are designed to perform a variety of functions, such as:

• emergency vehicle lighting
• interior vehicle lighting
• load manager and sequencer
• temperature control
• engine speed regulation
• oxygen pressure
• open door indicator
• other customer specified emergency vehicle equipment functions

Some modules perform a specific function (i.e. temperature sensors, backup sensors) while others perform an array of functions. Features common to all modules increase their reliability and performance.

Some modules are provided in a variety of sizes to accommodate customer requirements. For instance, a control module may be ordered with 6, 12, 18 or 26 digital outputs.

Once the number of variables to be controlled is established for a given vehicle, the modules are selected and the control and information strategy is programmed into each module by either the customer or ECX.

The programming software is intuitive, easy to use and available from ECX for installation in an office computer running Windows 2000 or higher.

To provide a means for performing control functions (i.e. turn lights, A/C, warning lights ON/OFF) and to be able to visualize system parameters (battery voltage, temperature set points, etc.) the multiplexed network incorporates different types of monochrome and color Liquid Crystal Display modules.

For those applications where it is more practical to provide a minimum of functions, ECX has engineered single-function modules such as:

• Load Manager
• Open Door Indicator and an Oxygen Monitor
• Temperature Sensor
• Clock / Elapsed Time Indicator
