SoMat eDAQ Base Processor
For the system that defines rugged, mobile data acquisition, it all starts here. The SoMat eDAQ Base Processor (ECPU-PLUS) is the foundation eDAQ systems are built from.
Specifically designed for these applications; input power for the system operates in a wide range from 10-55 VDC. Internal back-up batteries also protect the eDAQ from unplanned power losses or low-voltage events. The ECPU-PLUS utilizes Ethernet communications, and hosts its own web server with a configurable IP. This combination allows the eDAQ to effortlessly communicate wirelessly through WWAN modems, 802.11 devices, or point-to-point wireless bridges. An HSS communications port works with the SoMat eDisplay to provide an operator real-time channels and test information in a rugged LCD display.
To manage test data, the ECPU-PLUS has the capacity to perform a broad range of on-board data processing. This includes custom computed channels, triggers, gates, boolean expressions, and the SoMat DataModes™. Any data acquisition system can collect a Time History, but utilizing the SoMat DataModes™ allows users to save data in multiple, easy to manage and analyze formats including Burst History, Time-at-Level, Event Slice, Peak/Valley and Rainflow Histograms.
There are three different memory options for an eDAQ system; Internal (up to 32GB), DRAM (upgradeable to 256MB), and External PCMCIA (up to 4GB).
Additionally, within the ECPU-PLUS Processor are 10 Digital I/O’s and 8 Pulse Counter channels. Optionally, the SoMat ECOM layer can be installed (ECPU-PLUS-COM); allowing for 3 dedicated CAN network interfaces, 1 Vehicle Bus Module Interface, and a GPS Communications port.

SoMat eDAQ Vehicle Network Communications Layer
The SoMat eDAQ Vehicle Network Communications Layer (ECPU-PLUS-COM) offers (3) CAN device interfaces, (1) Vehicle Bus Module (VBM) interface, and a GPS communications port. It is an extremely versatile layer providing a direct correlation between vehicle bus channels with physical data (analog, thermocouple and frequency) as well as GPS. Up to 254 vehicle bus channels can be recorded per input, allowing total eDAQ system channel counts to be virtually limitless. Unlike other data acquisition products, vehicle bus channels do not consume any analog inputs. In fact, all 254 channels are input directly through a single connector.
The ECOM can be used as a passive eavesdropper on the controller network, or when needed, it can become an active participant making requests for specific information. A simple ‘logical masking' scheme is utilized to identify required frames in an easily managed textual database, which identifies where a unique message lay within the frame. By using these methods, not only is it a very short learning curve to master its use, but it is easily manipulated using tools such as Microsoft Excel, wherein PGN's (Parameter Group Numbers), PID's (Parameter Identifiers) or even direct address information can be added or modified. The layer comes with many predefined databases such as J1939 and OBDII, so it is as easy as ‘point and click' to get standard information.
The GPS communications port is designed to work with SoMat GPS devices.
