Haltech HT051100, Quick Start Manual

The 

Haltech CAN Network 

The Haltech CAN network allows for simple and effective expansion in ECU capability 
and functionality without having to go to the trouble of wiring in a whole new computer.

Expansion is made possible by the addition of multiple expansion devices that 
communicate to the main ECU via a Control Area Network (CAN).

Installation time and costs are kept to a minimum as all expansion devices are 
powered up from the main ECU via the pre-terminated connection cable that comes 
with each expansion device. 
Simply connect the device directly to the 8 pin CAN connector on the rear of the ECU 
or connect using an optional Haltech CAN Hub (order as part # HT059991) if multiple 
expansion devices are required).

Each expansion device is pre-programmed with a unique ID code which allows it to 
be recognised on the network and work correctly first time every time.
