curtisinstruments.com/360view

▶ Fully customizable instrument. You design your own instrument to your 

specific applications and needs, with a wide palette of possibilities.

▶ Analog, digital & CAN functionality in one instrument. All aspects of 

vehicle management, control and display can be accommodated. 

▶ CAN communication allows seamless interconnectivity with other 

system components, such as motor controllers.

▶ Microprocessor based logic eliminates or reduces the need for auxiliary 

vehicle circuits, such as timing circuits.

▶ One hardware set can be instantly programmed into a wide range of 

OEM specified instrumentation for use in a variety of different vehicles. 

▶ Large, easy-to-read dot matrix LCD is backlit for ideal viewing in all 

lighting conditions.

▶ Variety of different backlighting choices available – green and white 

are standard.

▶ enGage® IV replaces up to 4 gauges. OEMs can view up to 4 traditional 

gauge functions simultaneously in a variety of styles including numeric, 

bar or simulated needle. 

▶ Up to 6 switched inputs are available to track status of critical vehicle 

parameters, such as over-temperature, parking break, low-fuel, etc.

▶ Displays can include multiple warning icons and an advisory line for 

hour meters, maintenance monitors and time-of-day clock. 

The Curtis enGage® IV is a microprocessor based instrument panel that can be customized to 

monitor, display and control numerous vehicle functions in a single integrated package. The 

panel is fully CANopen compatible.

Digital Instrumentation

▶ Provides more information, such as diagnostics to the operator, 

while eliminating unnecessary wiring. 

▶ Password protected, enabled field-programming of maintenance 

monitoring, elapsed time and battery discharge profiles matches 

the panel to the specific user application.

▶ Visual warnings include flashing LCD icons and bargraph 

segments, and dual color warning LED.

▶ Three 1-Amp FETs are used to control OEM specified vehicle 

functions, such as alarms, lift-lockout, etc. 

▶ For battery powered vehicles, innovative Curtis battery 

monitoring technology provide reliable state-of-charge 

information.

▶ It’s easy for the operator to access and change parameters and 

display menus with accessible front panel buttons.

▶ IP65 rated front panel (IP 40 rear) assures performance in the 

harshest environments.

▶ Easy Snap-Fit design and integrated connector lowers production 

costs by eliminating traditional mounting hardware kits. (Optional 

mounting bracket available.)

▶ Available in an M-style housing for front (with overlay) panel 

mounting or behind (without overlay) panel mounting, T-style 

housing for front panel mounting or P-style module for behind 

panel mounting for OEM design flexibility.

▶ Reliable solid-state design means no moving parts to wear out.

▶ Attractive contemporary styling enhances vehicle design and 

maximizes readability.
