1. Introduction
The ProDAQ 3411 Enhanced ADC function card provides 24 differential inputs with an input range
of up to ±10V. The channels are multiplexed into a gain and filter stage with a software selectable
gain of 1 to 1000 and three different filter settings to choose from. A 16-bit Analog-to-Digital
Converter sampling with 100 kHz converts the signal. The result can be used directly or buffered in
an on-board FIFO for asynchronous operation.
For calibration, the internal ground as well as the voltage reference bus from the ProDAQ
motherboard can be included in the measurement as a 25
th
and 26
th
channel.
The ProDAQ 3411 function card is one of a range of function cards designed to provide full
functionality when installed in one of the range of ProDAQ motherboard modules such as the
ProDAQ 3120.

2. Installation
2.1. Unpacking and Inspection
The ProDAQ module is shipped in an antistatic package to prevent any damage from electrostatic
discharge (ESD). Proper ESD handling procedures must always be used when packing, unpacking
or installing any ProDAQ module, ProDAQ plug-in module or ProDAQ function card:
•Ground yourself via a grounding strap or similar, e.g. by holding to a grounded object.
•Discharge the package by touching it to a grounded object, e.g. a metal part of your VXIbus
chassis, before removing the module from the package.
•Remove the ProDAQ module from its carton, preserving the factory packaging as much as
possible.
•Inspect the ProDAQ module for any defect or damage. Immediately notify the carrier if any
damage is apparent.
2.2. Reshipment Instructions
Use the original packing material when returning a ProDAQ module to Bustec Production Ltd. or
calibration or servicing. The original shipping carton and the instrument's plastic foam will provide
the necessary support for safe reshipment.
If the original anti-static packing material is unavailable, wrap the ProDAQ module in anti-static
plastic sheeting and use plastic spray foam to surround and protect the instrument. Reship in either
the original or a new shipping carton.

2.3. Preparing the ProDAQ Module
To install a ProDAQ Function Card into one of the ProDAQ Motherboards, you need to remove the
modules top cover:
1 - Module Cover 2 - Cover Screws 3 - Cover Hooks
Figure 1 - Removing the ProDAQ Module Cover
To remove the top cover, remove the one countersunk screw in the back and the two panhead
screws towards the front panel (), that hold the cover in place. Remove the cover by sliding it out
of its position towards the VXIbus connectors and up. Take special care about the hooks ()
holding it into place. Try not to lift the cover straight up. See Figure 1 for the location of the screws.
To re-install the cover, slide it back into its position by placing the small hooks over their holes and
moving the cover down and forward. Secure the top cover using the two panhead screws and one
countersunk screw ().
