Appendix E: Using the Configuration Tool Software
ECM’s Configuration Tool runs on a PC and is for use with ECM’s analyzers and modules.
The Configuration Tool is supplied on a CD with each analyzer and module and is available
for download on www.ecm-co.com .
The Configuration Tool can be used for the following:
1. To produce a .dbc file for one or more analyzers on the same CAN bus.
2. Real-time display of data from analyzers. Only one analyzer’s data is shown at a
time.
3. Log data from one or more analyzers.
To connect a PC to the CAN connector on the back of an analyzer requires the supplied
cables (see Figure 2) and a USB-to-CAN adapter. Make sure the CAN bus is properly
terminated. The following adapters are supported: Kvaser, ETAS, Peak USB to CAN
adapters, and the VectorCAN CAN adapter card. Driver software for one of these adapters
must be installed prior to using the Configuration Tool. Driver software will be supplied
with the adapter or be available on-line.
Once the analyzer(s) are connected to the CAN bus and turned on, leave “Exclusive”
checked, start the Configuration Tool, select the “Analyzers” tab, select the CAN Adapter,
leave “Exclusive” checked, and then press the start button. “Status:” should change to “Port
Opened”.
 Producing a .dbc File
Devices receiving CAN messages from one or more analyzers must understand the format of
the messages. A .dbc file is used to describe the format. Using the Configuration Tool, a
.dbc file describing the format of messages from one or more analyzers on the same CAN bus
can be created.
Each analyzer communicates eight pieces of data, two error codes, and two auxiliary codes.
The eight pieces of data are: what is being sent to the six analog outputs and what is sent to
the upper and lower displays. Before producing a .dbc file for the analyzer(s), each analyzer
on the CAN bus should have its displays and analog outputs programmed for the desired
data. It is important to note that if a parameter that is being displayed is changed (by pressing
the

or

key), the CAN data will also be changed to that newly displayed parameter.
Similarly for an analog output. LOCKing the display head can be used to avoid this problem.
Once the analyzer(s) have been programmed, send (one analyzer at a time) each analyzer’s
message format to the Configuration Tool.
