1. Introduction
This manual describes the ProDAQ 3120 Motherboard and explains how to install and configure
the ProDAQ 3120 Motherboard with any of the ProDAQ Plug-in Modules and ProDAQ Function
Cards.
The ProDAQ 3120 Motherboard provides a VXIbus interface and common resources like a voltage
reference module (optional), trigger routing capability and additional power regulators for up to
eight ProDAQ function cards. The ProDAQ 3120 Motherboard together with the ProDAQ Function
Cards can be configured to provide any function or combination of functions required for a specific
application.
The ProDAQ 3120 Motherboard is part of the ProDAQ Modular Data Aquisition System, which
consists of the following components:
AProDAQ Motherboard that installs into a VXI slot in a VXIbus chassis. A ProDAQ
Motherboard can be populated with a ProDAQ 3201 Voltage Reference Plug-in Module
(optional) and up to eight ProDAQ Function Cards.
The ProDAQ 3201 Voltage Reference Plug-in Module that installs into the Voltage Reference
Plug-in slot on a ProDAQ Motherboard.
The ProDAQ Function Cards which install into ProDAQ Bus slots on a ProDAQ Motherboard.
The ProDAQ Signal Conditioning Unit can be used together with the ProDAQ Modular Data
Aquisition System to provide various signal conditioning functions and allows for easy connection
to the existing installation.

2. Installation
The ProDAQ 3120 Motherboard is shipped in a VXI module enclosure, ready to be installed in a
VXIbus chassis. The function cards can be factory-installed or field-installed later on. The front-
panel is populated with filler panels for each ProDAQ function card slot, which should be left in
place unless a ProDAQ function card is installed in the slot. The ProDAQ function card slots are
arranged in four stacks of two function cards each.

2.1 Unpacking and Inspection
Before unpacking the ProDAQ module, check the exterior of the shipping carton for any signs of
damage. All irregularities should be noted on the shipping bill.
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 Plug-in Module or a ProDAQ Function Card as well as to configure the
addressing mode of the ProDAQ 3120 Motherboard, you need to remove the modules top cover.
1 - Module Cover 2 - Cover Screws 3 - Cover Hooks
Figure 2 - Removing the ProDAQ Module Cover
To remove the top cover, remove the undercut flathead and two panhead screws that hold the
cover in place and 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 2 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 three undercut flathead
crews.
2.4 Installing a ProDAQ Function Card
The ProDAQ Function Cards are arranged inside the ProDAQ Module in four stacks of two cards
each. The function cards are mounted face down, e.g. the front-panel connector as well as the
motherboard connectors are underneath the PCB.

To install a ProDAQ Function Card in any of the possible positions, use the following procedure
(See figure 3 for reference):
Remove the top cover of the module as described earlier in this chapter (Fig. 3, Pos. 1).
Remove all screws on the front-panel holding installed function cards or double filler panels in
place (Fig. 3, Pos. 2). Screws holding single filler panels don't need to be removed.
Remove the two panhead screws that mount the front panel to the modules bottom cover (Fig.
3, Pos. 6).
Please take special care of the module handles and the rings (Fig. 3, Pos. 3 and 4), which are
also fixed by those screws. The mounting angle (Fig. 3, Pos. 5) stays fixed to the front panel.
Remove the front panel by moving it forward carefully so as to avoid bending the installed
function cards.
Choose the stack and position (lower or upper) where you want to mount the function card. If
the stack, in which the function card should be installed, is covered by a double filler panel, you
have to remove it before installing the function card.
Remove the three 2.5mm panhead screws and the crinkle washers from the stack's standoffs
(Fig. 3, Pos. 9 and 10 for example).
If you want to install a function card in the upper position of a stack without having a function
card in the lower position, you need to mount both spacers (Fig. 3, Pos. 11) on each standoff. If
the stack is already populated with a function card in the lower position, mount only the bigger
spacer (Fig. 3, Pos. 8) onto each standoff.
Place a bayonet (supplied) on each standoff. Align the function card over these and slide
carefully down. The function card should be held parallel to the modules bottom cover all the
time during its way down.
Fix the function card by mounting the three 2.5mm panhead screws and the crinkle washers
onto each standoff. If you install a function card in the lower position of a stack, you need first
to mount both spacers (Fig. 3, Pos. 11) onto each standoff.
Re-mount the modules front-panel. If there is only one function card mounted in a stack, cover
the remaining opening in the front panel by a single filler panel.
Re-mount the modules top cover.
