Introducing the TDAS G5 Data Acquisition
System
Each TDAS G5 Data Acquisition System (DAS) is a standalone, 32-channel, data acqui-
sition system. This manual discusses the features and options available with the
TDAS G5 DAS. To identify the specific hardware included with your system, please see
your packing list.
Overview of TDAS G5 DAS Features
•
Designed and manufactured to withstand in-dummy and on-vehicle dynamic
testing environments.
•
32 programmable sensor input channels, each with an independent excitation
source, true differential instrumentation amplifier, anti-alias filter, 16-bit analog-
to-digital converter, and electronic identification (EID) support.
•
Adjustable sampling rate of 250 to 100,000 samples/second/channel.
•
Primary memory: 150 seconds* at 10k samples/second (RAM); back-up
memory: 7 seconds at 10k samples/second (non-volatile flash).
•
Voltage insertion and shunt emulation.
•
32 multi-purpose digital input channels.
•
Ethernet 10/100BaseT/Tx communications.
•
Simple 216-position interface connector.
•
LED indicators for communication, calibration, power, arm status and event
status.
•
Back-up battery input for safe operation even with loss of primary power.
Please see the DTS web site (
) for the latest hardware specifications.
Input Range
Each sensor channel has a true differential instrumentation amplifier with an input range
of ±2.0 V at a gain of 1. The input amplifiers function nominally between 0 and 5 V,
therefore input signals must be centered 2.5 V above minus excitation for proper
operation. Be sure to consider this when connecting something other than typical bridge
sensors (i.e., signal generator, amplified sensors, etc.).
Excitation Sources
All excitation sources are individually regulated and limited to ensure reliable operation
even with shorted cables. The standard excitation voltage is 5.0 V. Excitation sources
are not turned on until the software initializes the system during the

modes.
Sensor Connectors
The TDAS G5 DAS is supplied with a 216-position interface connector that has sensor
connections as shown below. The pin assignments can be found in Appendix A.
* Earlier units may contain less RAM. See the section on Memory Size (page 6) for additional details.
