J1708 Vehicle Bus Module

Overview

The SoMat J1708 Vehicle Bus Module (EVBM-J1708) conditions J1708 vehicle network parameters to be synchronously measured by eDAQ and eDAQ-lite systems.

Up to 254-channels can be conditioned per VBM Module. It can be used as a passive eavesdropper on the controller network, or when needed, 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, but it is easily manipulated using tools such as Microsoft Excel® where PGN’s (Parameter Group Numbers), PID’s (Parameter Identifiers) or even direct address information can be added or modified.
