Somat eDAQ lite
5.9 Vehicle Bus Module
The ELDIO and ELCOM layers support vehicle bus modules (VBM). For the ELDIO,
only connectors |1-4| and |5-8| support a VBM. Use a SAC-EXT-VB Extension Cable
(1-SAC-EXT-VB-2) to connect the VBM and eDAQ
lite . If using an additional extension
cable, make sure the cable connected directly to the eDAQ
lite is the SAC-EXT-VB
cable. Keep cabling less than 30 meters in length to avoid transmission failures.
Plug in the VBM with the eDAQ
lite power off. When power is supplied, the eDAQ lite
recognizes the VBM during boot up. Each VBM supports one type of vehicle bus
hardware interface. The available VBMs are:
• CAN
• J1850 VPW
• J1708
• ISO9141/KWP2000
• MIL1553
5.9.1 VBM Available Inputs
Vehicle Bus
Each vehicle bus module supports up to 254 channels. The available channels
depend on the vehicle bus type and the selected databases. When the eDAQ
lite
receives vehicle bus message packets, they are time stamped, processed into
individual data streams and re-sampled as necessary to the user-selected output rate.
For more information on setting up vehicle bus inputs, see “Bus-Oriented Input
Channels” on page 121.
Vehicle Bus Message
A vehicle bus message channel acquires raw vehicle bus packets. Every packet is time
stamped upon receipt and can subsequently be stored in the specialized Message
Logger DataMode. For more information on setting up vehicle bus message inputs,
see “Vehicle Bus Message Channel” on page 123.
5.9.2 VBM Configuration Options
NOTE
These configuration options also apply to the dedicated CAN interface on the ELCOM
layer and the serial bus port.
Hardware Interface
Select the desired vehicle bus hardware interface.
Databases
Select one or more database files from the presented list. The selected databases
determine the channel types available when adding a vehicle bus channel to the test
setup.
