Dearborn Group Industrial DPA - RS-232 ASCII Command Interface
The DG Technologies Industrial DPA (DG-DPAIII/I) and Embedded DPA (DG-EDPA-SI) provide
a simple-to-use ASCII communications interface to vehicle databus networks over a
standard RS-232 communications port.

This ASCII command interface is extremely useful for SCADA (Supervisory Control And Data Acquisition) and Programmable Logic Controller (PLC) systems that monitor and control industrial applications using gaseous or diesel engines as primary or backup power. These systems can send simple ASCII commands through the RS-232 port that will tell the DPA to transmit or receive vehicle messages.
The Industrial DPA has been deployed in very diverse roles such as natural gas genset farms, water and sewage pumping stations, mining trucks, and for hospital backup generator monitoring. The ASCII command interface makes interfacing these power units to machines, onboard controllers, and monitoring systems easy.
Other potential applications allow vehicle databus communications through a PC's serial port using a terminal emulation program (such as HyperTerminal), onboard vehicle controllers (i.e. Telematics, Event Data Recorders), or a PDA-type device such as an iPod or Android.
The Industrial DPA is based upon the successful DPA III Plus product. The DPA III Plus provided a TMC RP1210 Application Programming Interface (API) to a PC via an RS-232 serial port. Not long after the DPA III Plus release, DG had many requests from companies wanting to monitor their power units but did not have a PC, or they did not have software engineers. DG responded by modifying the interface between the PC and the adapter so that a machine (i.e. PLC or SCADA system) could easily connect, read and send vehicle databus messages.
The eDPA is based on the highly successful DPA 4 Plus (a USB-based diagnostics adapter). More information on the eDPA can be found on the eDPA Website.
- All DPA models come with a two-year limited warranty.
- Our technical support team has years of industry experience to help you get the most from your investment.
- Should a tool need to be returned to the factory, the RMA repair process is simple, and turnaround is generally same-day.

Example RS-232 ASCII Data Session
The following example shows how simple the Industrial DPA is to use.
Lines starting with a '//' are comments to add clarity to the example.
|
// Open J1939 communications (@250k) with 29-Bit CAN Identifiers (CANID)
INIT,3,41,58,0,0,0
// Send a J1939 message with 29-Bit CANID of 0x010780 (hex) with 8 bytes of data.
TX,3,010780,11,22,33,44,55,66,77,88
// Load 29 bit CAN mailbox 1 to receive CANID 0x103234 and send back data count,
// data, CANID and time stamp with max of 8 data bytes.
LM,3,1,103234,1fffffff,0,F,8
// Response from DPA that message has arrived
