Haltech Elite CAN HUB 4 Port DTM-4

Haltech Elite 4-Port DTM-4 CAN Hub with 300 mm CAN Cable

Part Number: HT-159000

The Haltech Elite CAN Hub provides a clean connection point for adding multiple Haltech CAN devices to a compatible ECU or VCU.

One port connects the hub to the ECU’s Haltech CAN System connection, leaving 3 ports available for devices such as a WB1 or WB2 wideband controller, digital dash, NEXUS IO16, CAN keypad, tire-monitoring system, or other compatible Haltech CAN hardware.

The hub is a passive network splitter and requires no software configuration. It distributes the Haltech CAN connection through standard DTM-4 connectors, allowing multiple devices to be connected without splicing the CAN wiring or building a custom junction harness.

Application Notes

• One hub port connects to the compatible Haltech ECU, VCU, engine harness, or an existing Haltech CAN network connection.
• The remaining 3 ports can be used for compatible Haltech CAN devices.
• The ports are functionally common; the hub does not have a dedicated ECU-input port.
• Typical connected devices include:
  • Haltech WB1 or WB2 CAN wideband controller
  • Haltech iC-7 or uC-10 digital dash
  • NEXUS IO16 input/output expander
  • Haltech CAN keypad
  • Haltech tire-monitoring system
  • Other supported Haltech CAN devices
• Although the official product name retains the Elite designation, the hub can also be used with compatible NEXUS systems that use the same DTM-4 Haltech CAN connection.
• The hub does not add ECU inputs or outputs and does not translate between different CAN protocols. It only provides additional physical connection points on the Haltech CAN network.
• Each connected device must still be enabled and configured through the appropriate Haltech software when required.
• More than one CAN hub can be connected when additional device ports are needed.
• Connected devices with 2 CAN ports may also be daisy-chained without a hub. The hub is most useful when a branched network layout is cleaner or when a device has only one CAN connector.
• Alternate DTM-4-to-DTM-4 CAN cable lengths are available separately for installations where the included 300 mm cable is too short.
• The DTM-4 Haltech CAN connection carries switched power and ground in addition to CAN High and CAN Low.
• The hub does not provide an independent power source. Available power for connected devices depends on the ECU or harness CAN supply and the electrical requirements of the attached devices.
• High-current CAN accessories, including multiple wideband controllers, may require a separate fused and relayed power supply as specified in the device’s installation documentation.
• The hub should be connected only to a CAN channel configured for the Haltech CAN System. A vehicle CAN or third-party CAN channel may use the same general type of communication but is not interchangeable without the correct protocol configuration.
