SVIM
VISIÓN GENERAL
The SVIM acquires data of the highest integrity for use in advanced chassis and suspension analysis. This versatile expander works in conjunction with Display Loggers C185, C187 or C1812 and Enclosed Logger L180 to facilitate the synchronised logging of high speed, high resolution inputs.
SVIMs are compact and can be located close to sensors, reducing the weight and complexity of wiring. When used in multiples, up to 200 sensor inputs are available.
CARATERISTICAS
- Samples 18 inputs at the same instant in time using 18 separate converters with 5th order anti-aliasing filters
- Supports many different types of sensors, including unamplified thermocouples and strain gauges
- Configured and controlled using Dash Manager software which has special programming functions for SVIM
- Multiple SVIMs are synchronised so every SVIM in the vehicle samples its high resolution AV inputs at the same instant in time – this is important when looking at the relationships of signals collected from different sensors around the vehicle and useful for test rigs and real time simulations

CABLEADO Y CONEXIONES
The SVIM is powered from the vehicle battery and connected to the Data Logger via the CAN bus.
Information on CAN bus wiring can be found in the Data Logger user manual, available for download from www.motec.com.au/downloads Please ensure wiring is according to CAN requirements and the CAN bus has at least one 100R terminating resistor.
The total available CAN bandwidth on a single CAN bus is 1 Mbit/sec. The bandwidth used by the total of all devices on the CAN bus must not exceed approximately 90% of this value (900000 bits/second)
If using multiple SVIMs and fast logging rates, it may be necessary to put some SVIMs on one CAN bus and some on the other to avoid exceeding the CAN bus bandwidth limit.
Approximate bandwidth = Total measurement rate (samples/second) x 30 (bits per sample)
The measurement rate for an input equals the logging rate or 50 Hz, whichever is higher.
The Dash Manager software will warn if the bandwidth is likely to be exceeded.
Example
- 4 channels at 2000 Hz
- 20 channels at 500 Hz
- 40 channels at 20 Hz (occupies 50 Hz)
Total measurement rate (samples/sec) = 4 x 2000 + 20 x 500 + 40 x 50 = 20000
Approximate bandwidth (bits/sec) = 20000 x 30 = 600000
