Haltech 15-Button CAN Keypad

Haltech 15-Button CAN Keypad — 3 × 5

Part Number: HT-011502

The Haltech 15-Button CAN Keypad provides a configurable driver interface for more complex Haltech NEXUS and Elite installations.

Each button appears in Haltech NSP as a CAN input and can be assigned to engine, drivetrain, power-distribution, or vehicle-control functions. Typical uses include engine start/stop, cooling-fan and fuel-pump overrides, traction-control settings, nitrous control, data logging, air-conditioning request, launch functions, lighting, and other programmable controls.

The larger 3 × 5 layout provides 15 controls in one compact panel, making it particularly useful with a Haltech PD16 or in vehicles where conventional switches, relays, and warning lamps are being consolidated into a programmable control system.

Button and Indicator Operation

• Green LED
  • Indicates the current state of the button.
• Amber LED
  • Indicates the output state of the function associated with the button.
  • For example, a cooling-fan override button can show that the fan is operating even when the fan was activated automatically by coolant temperature rather than manually through the keypad.
• Red LED
  • Indicates a DTC or an error associated with the assigned function, input, or output.
• Momentary mode
  • The button remains active only while it is pressed.
• Push-on/push-off mode
  • The first press activates the button and the next press deactivates it.
• Startup-state control
  • A latched button can start in the Off state, On state, or its last state before shutdown.

Application Notes

• The keypad is compatible with Haltech NEXUS and Elite devices.
• It is not compatible with Haltech Platinum-series or earlier ECUs.
• The keypad connects to the Haltech CAN network using the included DT-4-to-DTM-4 adapter and 1,200 mm DTM-4 CAN cable.
• The keypad has one CAN connector and does not provide a second connection for daisy-chaining another device.
• A Haltech CAN hub or another CAN device with an available pass-through port may be required when the system already includes a dash, wideband controller, IO16, PD16, or other CAN accessories.
• Once connected, the keypad appears in NSP and must be enabled under the Haltech CAN System configuration.
• The correct 3 × 5 keypad option must be selected in the CAN-device configuration.
• Each button is assigned as an input within the configuration of the function it will control.
• Typical keypad functions can include:
  • Engine start/stop
  • Cooling-fan override
  • Fuel-pump override
  • Air-conditioning request
  • Traction-control enable or adjustment
  • Nitrous enable or override
  • Data-logging start and stop
  • Pit-lane speed limiter
  • Launch-related functions
  • Transbrake functions
  • Generic output overrides
  • Generic condition controls
  • Lighting and accessory controls through a PD16
  • Dash-page selection when assigned through a compatible Haltech dash
• Keypad buttons can be assigned to functions that accept a state-type CAN input.
• The keypad cannot replace a sensor or provide an analog measurement. Functions requiring a pressure, temperature, speed, brake, clutch, or other physical sensor signal still require the appropriate wired input.
• Haltech specifically identifies brake-switch, clutch-switch, and water-injection safety inputs as examples that cannot be replaced by keypad buttons.
• The keypad sends commands over CAN; it does not directly switch fans, pumps, lights, solenoids, starter motors, or other electrical loads.
• The commanded load must be operated by an appropriate ECU output, PD16 output, relay, or other power-control device.
• The larger 15-button keypad is particularly useful with the NEXUS PD16, where individual buttons can control vehicle circuits without requiring a separate physical switch and ECU input for each function.
• Button backlight and status-LED brightness are configured separately in NSP.
• When the keypad first establishes communication with the ECU, all LEDs flash briefly to confirm communication.
• The LEDs also flash when the backlight or status-LED brightness settings are changed.
• With current Multi-master CAN firmware, individual buttons from the same keypad can be divided between a compatible Haltech ECU and an iC-7 or uC-10 dash.
• For example, some buttons can operate ECU functions while other buttons control dash functions or PD16 circuits assigned through the dash.
• The same individual button cannot be assigned simultaneously to more than one master device.
• A conflicting button assignment generates a DTC and illuminates the affected button’s red error LED.
• With Multi-master CAN enabled, an unassigned button does not illuminate its status LEDs when pressed, although NSP can still display the button state.
• Current Multi-master CAN functionality requires, at minimum:
  • NEXUS ECU firmware 1.28.x
  • Elite ECU firmware 3.12.x
  • iC-7 or uC-10 firmware 2.28.x when a dash is used as a master
  • NSP software 1.40.x
• All current Haltech CAN keypads are compatible with Multi-master CAN.
• In supported installations, the keypad can be controlled by a compatible Haltech dash without an ECU. The dash acts as the master device in that arrangement.
• The included label set uses semi-transparent labels so the selected function icons remain visible with the keypad backlighting illuminated.
• The keypad requires a flat mounting surface.
• Installation should provide adequate clearance behind the panel for the keypad connector and CAN adapter harness.
• The 15-button keypad measures approximately 5.13 × 3.58 in. before allowing for the rear connector and wiring bend radius.
