Powerful: The DPA RF(Protocol Adapters) is a wireless tool used to get truck data and diagnose problems. Even if the truck is outside the service bay, the DPA RF(Protocol Adapters) 2 mile communication range lets you easily connect your trucks to computers equipped with OEM diagnostic software. Avoid expensive computer damage because only the rugged and compact DPA RF(Protocol Adapters) tool moves.

Secure: Our DPA RF(Protocol Adapters) uses proprietary digital RF communications for better data security than 〝standard〞 wireless applications. This means competitors can’t access your development information by parking near your service bay with a portable laptop and downloading your data. And because this special wireless technology does not interfere with standard 802.11 wireless communications, your Information Technology people don’t need to be involved.

Flexible: Getting data from trucks located outside the shop lets you know in advance what kind of service each truck needs. This vehicle 〝pre-screening〞 means you can schedule work on vehicles that need urgent maintenance first. The DPA RF(Protocol Adapters) helps to avoid having a service bay occupied with a truck and a mechanic for 30 minutes or more – to learn that the truck does not need service.

The DPA RF(Protocol Adapters) also has special modems that will switch to an unused frequency to avoid signal connection problems. This means that multiple DPA RF(Protocol Adapters) systems can be used in the same garage with no wireless communication conflict issues.

Easy To Install: The included Installation CD makes getting up and running easy. It was designed for problem free installation to immediately start using the DPA RF(Protocol Adapters) product.

Development Interface: If a custom software application is required, we supply libraries so you can use C, Visual Basic, LabVIEW, TruckConnectTM, etc.

Supported Protocols: CAN (canbus), GMLAN, J1587, J1708, J1922, J1939 (CAN), J2284, J2411 (GM SW). Additional protocol support is available.
