• We recommend to always connect unused inputs to the corresponding reference ground to
avoid crosstalk between the input channels.
• Always disconnect the eld wiring of the analog and digital inputs/outputs from the signal
conditioning unit (ADQ-SCU incl. plug-in boards) as well as the connection to the ADQ-348
before connecting or disconnecting the power supply of the signal conditioning unit.
• Make sure that no static discharge can occur through the device when handling the card.
Follow standard ESD protection measures.
• Never connect the devices to live parts, especially not to mains voltage.
• Precautions to avoid unpredictable misuse must be taken by the user.
ALLNET® GmbH Computersysteme is not liable for improper use and resulting damage.
1.3 Installation and assembly site
The signal conditioning unit (ADQ-SCU incl. plug-in boards) is intended for installation in
measuring and test systems by qualied personnel. The relevant installation regulations and
standards must be observed.
The ADQ-SCU may only be used in dry rooms. Ensure sufcient 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.
1.4 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.
Important features:
• Analysis of audio signals of different levels
• Adjustable input coupling (AC/DC), digital lters, gain and attenuation
• Measurement and mathematical evaluation of relevant parameters
• Monitoring level for listening to all audio channels
• Generation of audio signals for stimulation of power ampliers
• Switch supply voltages via relay, optional: ADQ-RB-16/8
• Switch currents up to 50 A (100 VDC) via relay, optional: ADQ-SCU-PB-50
• e.g. connect the supply voltage to the DUT
• Customer-specic extensions via plug-in modules
• Simple control via ALLDAQ driver system
• API for easy integration into your application
• Optimized for operation with the isolated ADQ-348 DAQ and control card

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.
The ADQ-348 provides the following basic functionality:
• 32 pseudo-differential 18 bit voltage inputs up to 800 kS/s
• Input ranges: ±10.24 Vp, ±5.12 Vp, 0-10.24 Vp, 0-5.12 Vp
• Insulation voltage A/D section: 1500 VDC (60 s)
• Four 16 bit voltage outputs (±2.56 Vp) up to 500 kS/s
• Insulation voltage D/A section: 1500 VDC (60 s)
• 16 TTL-DIOs (3.3 V/5 V), max. 20 mA per output
• 8 isolated digital inputs (High: 15..35 V)
• 8 isolated digital outputs up to 600 mA/output
• Isolation voltage DI and DO part: 500 VAC
• Special functions via HDMI connector: 32 bit counter, I2C bus port, incremental encoder
port, frequency measurement, PWM output

3.4.11 Audio output (STB19)
Stereo audio output for connecting headphones. The output is relay-switchable so that the
audio outputs of several baseboards can be wired in parallel.
Caution:
In case of parallel connection of audio outputs of several baseboards, you must ensure that two
or more outputs are never active at the same time (relay closed). Otherwise the output stage
can be destroyed.
