Please read - before installing and programming the device - this manual carefully! Scope of delivery • ALLDAQ Baseboard ADQ-SCU-BB for signal conditioning unit • ALLDAQ ADQ-SCU-BTB adapter • 2 x 68-pin VHDCI cable (male-male), double shielded, cables twisted in pairs, length: 1.8 m (ADQ-CR-VHDCI-68M/68M-1.8m), part no.: 146813 (2 x)
The relevant installation regulations and standards must be observed. The ADQ-SCU may only be used in dry rooms. Ensure sufficient heat dissipation. Ensure that the connecting cables are securely attached. The installation must be carried out in such a way that the cables are not under tension, otherwise they may become loose.
Introduction Brief description The ALLDAQ ADQ-SCU signal conditioning unit was developed to optimally adapt a large num- ber of analog and digital inputs/outputs to the requirements of a complex, automated measure- ment and test system. Signals are acquired and generated synchronously via the multifunctional ALLDAQ ADQ-348 measurement and control card, which simultaneously controls the ADQ-SCU via I2C bus.

The ADQ-SCU was developed for connection to the multifunctional ALLDAQ ADQ-348 measure- ment and control card, which simultaneously controls the ADQ-SCU via I2C bus. The connection is made via two 68-pin VHDCI cables and one HDMI cable for various special functions such as the I2C bus for controlling the ADQ-SCU.
Typical confi guration from an ADQ-Express measurement system, equipped with 2 multifunc- tion cards of type ADQ-348 to control one signal conditioning unit ADQ-SCU each. In addition, one current measurement channel of the ADQ-412 is connected to one ADQ-SCU-PB-50 power board per DUT.
