Please read – before installing and programming the device – this manual watchfully! Scope of delivery • ALLDAQ base board ADQ-SCU-BB for signal condition unit • Mezzanine board ALLDAQ power board ADQ-SCU-PB • Mezzanine board ALLDAQ relay board ADQ-SCU-RB Optional: • 2 x 68-pin VHDCI cable (male - male), double-shielded, twisted-pair wires, length: 1.2 m...
All relevant installation instructions and standards must be followed. The ADQ-SCU may only be used in dry rooms. Ensure a very good ventilation. Take care for proper fitting of the connection cables. Installation has to be done in a way that the cables are not in tension else they could release itself.
Introduction Short description The ADQ-SCU signal condition unit was developed to optimally adapt a large number of analog and digital inputs/outputs to the requirements of a complex, automated test system. The sig- nals are acquired and generated synchronously via the ADQ-344 multi-function measurement and control board, which also controls the ADQ-SCU via I C bus.

The system in overview Manual ADQ-SCU Rev. 1.01 Multi-function board ADQ-344 The signal condition unit ADQ-SCU was developed for connection to the multi-functional data- acquisition and control board ALLDAQ ADQ-344, which also handles controlling the ADQ-SCU by I C bus. The connection is established by two 68-pin VHDCI cables and one HDMI cable for miscellaneous special functions like the I C bus controlling the ADQ-SCU.
Typical configuration with an ADQ-Express measurement system, equipped with 2 multi-func- tion boards of type ADQ-344 for controlling one signal condition unit ADQ-SCU each. Further- more for each DUT one current measurement channel of the ADQ-412 will be connected with a power board ADQ-SCU-PB.
