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.
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.

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.
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

ProDAQ 3150 User Manual 3150UM-01
Bustec Production Ltd. Page 9
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 screws.
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 connectors 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.

Removing a ProDAQ Function Card
Removing a ProDAQ Function Card is exactly the the reverse operation then installing it. After removing the
top cover and the front panel as described previously, remove the three roundhead screws that fix the
function card(s) on the standoffs.
Take special care when removing the function card(s) not to bend the motherboard connectors.
After removing the function card(s), install the correct combination of spacers on the standoffs. If a stack is
populated with only one function card, each of the standoffs needs to be mounted with both spacers to cover
the distance between the cards as well as the PCB thickness of the missing card. If a stack is populated with
two function cards, only the bigger spacer must be mounted.
Fix any remaining function card again by mounting the three panhead screws on the standoffs, re-mount the
front panel and the modules cover.
Installing a ProDAQ Plug-in Module
The ProDAQ 3150 Motherboard Module allows the installation of a Voltage Reference Plug-in Module for
calibration purposes, a ProDAQ 3250 DSP Plug-in Module and memory modules.

Configuring the ProDAQ 3150 Motherboard
The ProDAQ 3150 Motherboard is fully software configurable. No strap or switch settings are necessary
except for the VXI Logical Address setting as specified by the VXIbus standard.
VXIbus Logical Address
Each device in a VXIbus system is assigned a logical address, either statically by the user or dynamically by
the resource manager. This logical address, a number between 0 and 255, defines the base address of the
board's VXIbus configuration registers in A16 space. Logical address 0 is reserved for the resource
manager, and address 255 is used to tell the resource manager to configure the board's logical address
dynamically. In this case a free logical address is assigned to the board by the resource manager.
The logical address of the board can be set by changing the setting of the 8-bit DIP switch on the back of the
board (See Figure 5). The "Open" or "Off" position of a switch corresponds to a logic value of 1 and the
"Closed" or "On" position to a logic value of 0. Keep in mind that each board in the system must be assigned
its own unique logical address (if configured statically) when setting the switch.

Overview
The ProDAQ 3150 Motherboard features a multi-bus architecture to optimize the data flow to/from the
ProDAQ function cards. The function cards are located on the ProDAQ bus in four stacks of two function
cards each. The ProDAQ bus can be accessed either by the VXIbus controller or from any master on the
iBus. The iBus interconnects the VXIbus controller, the memory, the on-board processor, the (optional) DSP
Plug-in Module, the internal communication registers and the ProDAQ Bus. It allows the on-board processor
and the DSP on the DSP Plug-in Module to access the function cards, the memory and the internal
communication registers.
VXIbus Interface
The VXIbus Interface Controller is responsible for handling of the VMEbus protocol, the VXIbus specific
signals, the VXI configuration registers and the access from the VXIbus to the board and it’s resources.
These resources are: the function cards, the trigger subsystem and the optional voltage reference, the
memory, the communication registers, the on-board processor and the optional DSP plug-in module.
As the ProDAQ 3120 Motherboard, the ProDAQ 3150 Motherboard allows the direct access of the function
card address space through the VXIbus interface by mapping it into the board's VXIbus address space.to
enable high data throughput, single word and block transfer access is provided. In addition a mask register,
located in the VXI configuration register set, can define a set of function cards involved in a multicast write,
or a read from multiple function cards. Broadcast write operations are also supported, to initiate a common
function in all function cards.
The ProDAQ 3150 Motherboard can be accessed from the VXIbus via byte, word, double word (32 bit) and
quad word (64 bit) access in the A32 address space. It occupies either 64 MBytes in the VXIbus A32
address space if used with 16/32MByte memory, ot 256 MByte if used with 64/128 MByte memory. In
addition to single word (either 8,16,32 bit) accesses VMEbus block transfer read and write is supported as
16 or 32 bit VME BLT transfers and 64bit MBLT transfer mode.
VXIbus Configuration registers
The VXIbus Configuration registers are located it the board's VXIbus A16 address space. The base address
fis dependent on the logical address of the motherboard, which can be selected by a the logical address
configuration switch, or if the logical address is set by this switch to 255 by software. The motherbard uses
the extended register device model, as defined by the VXI-2 Standard.
Interrupter
The VXIbus Interface Controller can generate a VXIbus interrupt on request of the on-board processor or the
processor on the optional DSP plug-in module via the internal communication registers. If a function card
want to request an interrupt, the appropriate function card trigger output line has to be routed to the interrupt
request input line of the VXIbus interface controller via the trigger switch matrix.

ProDAQ 3150 User Manual 3150UM-01
Bustec Production Ltd. Page 17
Memory
The memory subsystem is organized in a dual bank fashion to allow maximum throughput to the VXIbus
system. either bank can be accessed simultaneously by both the VXIbus controller and a master on the iBus.
Which bank is accessible can be selected, so that a double-buffering scheme can be implemented to
maximize the data throughput.
On-board processor
The on-board processor controls the ProDAQ 3150 motherboard. It is responsible for initializing the
motherboard and function cards after power-up and reset, handles the communication with a host and
provides fast data-movement capabilities. It is located on the iBus and is equipt with local SRAM and FLASH
memory.
Communication/Arbitration Controller
The communication/arbitration controller provides mailbox registers for the communication between the
different masters on the motherboard and implements a resource sharing protocol. Each of the masters on
the motherboard (A VXIbus master via the VXIbus interface, the on-board processor and the optional DSP)
has two mailbox registers to communicate with the two other masters. Writing to such a mailbox register may
cause an interrupt to the corresponding master.
Arbitration is provided for access to the shared resources on the the motherboard. Shared resources are:
• the function card stacks A, B, C and D
• the trigger switch matrix interface
• the voltage reference interface
The on-board processor is by default owner of all shared resources. Other masters will have to request a
resource from the on-board processor.

ProDAQ 3150 User Manual 3150UM-01
Page 18 Bustec Production Ltd.
The Trigger and Interrupt System
The trigger and interrupt system on the ProDAQ 3150 Motherboard is build using a programmable trigger
switch matrix. The switch matrix allows to connect all trigger sources and sinks available:
Function Card Trigger Outputs
Each function card features one trigger output line, allowing the function card to send a
trigger to the switch matrix.
Function Card Trigger Inputs
Each function card features one trigger input line, which can be used to send trigger or clock
signals to the function card.
VXIbus TTL/ECL Trigger Lines
The VXIbus TTL/ECL trigger lines can be used to send or receive trigger signals from other
VXIbus devices or the controller.
VXIbus Interface
The VXIbus interface features one trigger input line, which can be used to generate an
VXIbus interrupt.
The clock signals for the function cards are also routed via the switch matrix to allow them to be shut off in
case no function card is fitted to a slot.
The switch matrix can be programmed to connect two or more of those sinks and sources together, so
that for example
• a function card output trigger line can be routed to a VXIbus trigger line
• a VXIbus trigger line can be routed to a function card trigger input line
• a function card trigger output line can be routed to a function card trigger input line
• a function card trigger output line can be routed to the VXIbus interface to generate an
interrupt.

Table 1 - The In/Output Ports of the Switch Matrix
In general 1:m as well as n:1 connections are possible, with some limitations on the type of lines involved in
the connection and the number of lines connected. Table 1 shows a complete list of signals connected to the
switch matrix. Because of the drivers involved to drive the trigger signals on the VXIbus, the VXIbus trigger
lines appear each as two signals, one input and one output, in the list.
The trigger and interrupt system is programmed via five registers, two in the VXIbus configuration register set
(IRQH and JTAG) and three registers located in the boards A24/A32 space.
