EquipmentWorld.com | November 2017 43 There are two types of functions taking advantage of CAN. There are those that do not have their own electronics, such as outriggers. When outriggers are deployed, signals on the CAN bus lock down other functions so the vehicle can't move. And then there are those that have their own electronics, such as weld- ers and cranes and a host of other equipment. Sharing information over the CAN bus optimizes these func- tions' safety and performance. Integrating the back of the truck with the chassis cab's CAN bus has become so essential that truck OEMs are offering their own upfit- ter interface boxes, a place where upfitters can plug in the tools and accessories they're adding to a truck. On a RAM truck, it's the VSIM, or Vehicle System Interface Module. On Ford, it's the Upfitter Interface Module, or UIM. Aftermarket suppliers also provide interface modules. For example, InterMotive, Auburn, California, makes modules for multiple mar- kets, and offers more than a dozen products for work trucks. InterMo- tive offers an upfitter interface mod- ule (they say theirs was the first), as well as specialty modules designed to serve specific functions. Their design parameters highlight key considerations for these products. Wherever possible, upfitters should avoid cutting and splicing wiring. InterMotive modules come with connectors to minimize the need for splices. In some instances, InterMotive has had to 3D print or mold connectors, depending on the volume required. Marc Ellison, director of InterMotive, says con- nectors are more reliable, speed up installation and make it far easier to decommission a vehicle. "Unplug our 'T' harness connections, plug the OEM connectors back together and you've returned the vehicle to its OEM state," he says. As with all electronic data sys- tems, CAN has gotten better and faster over the years with more bandwidth. But the demands on the system have grown, as well. There are two ways of gathering informa- tion from the CAN bus, active data acquisition (ADA) and passive data The CPA 295 drilling attachment mounts quickly and drills like a dream. It's a versatile, powerful excavator attachment that reaches a depth of 72.5 feet with its five-rod-capacity carousel. Its exclusive IntelSense electronic drilling control system automatically adjusts pressure to the rock hardness and ground layout, extending component life and increasing your uptime. 2905 Shawnee Industrial Way Suwanee, GA 30024 ussales@montabertusa.com 866-588-8690 Engineering Innovation since 1921 Montabert and the Montabert logo are registered trademarks of Montabert S.A.S. in the United States and various countries around the world.
