TDAS PRO Laboratory System
TDAS PRO LAB hardware utilizes a standard 19-inch, rack-mounted system commonly used for stationary laboratory data collection. Each rack supports 6 modules of TDAS PRO SIM, or TOM in any combination. The TDAS PRO LAB SIMs and TDAS PRO LAB TOMs and the mounting rack is electronically identical to their crashworthy counterparts except TDAS PRO LAB equipment is not crashworthy and contains no backup power source.
As with crashworthy TDAS PRO, several racks may be daisy-chained to form systems with large channel counts.
Overview of TDAS PRO LAB System Features
8 sensor input modules per rack
TDAS PRO LAB functions are set-up using an IBM-compatible computer. Once the
computer initializes the system, it can be disconnected and the module
will collect data with no additional support. After the test, data stored
in each module is downloaded to the PC hard drive in binary format. Once
on the hard drive, the binary data files are then unpacked for viewing
and post-processing. There are no potentiometers to adjust because hardware
settings are performed completely under software control. Every time a
data collection task is initiated, the software runs a thorough calibration
check on each measurement channel. Appropriate gains are set, sensor offsets
are zeroed and anti-aliasing filters are set. Sensor inputs are through
a 68-pin, high-density, D-sub connector located on the front of each TDAS
PRO LAB SIM module.
Up to six 8-channel modules can be installed in the available 19" rack.
Several racks may be daisy-chained to form systems with large channel
counts. The rack unit distributes communication signals, operating power,
power-up control, trigger signal, and slot programming codes. The rack
also contains a 1000-volt, isolated, time zero trigger buffer, power status
indicator and provisions for using RS232 communication protocols.
