SECTION 1 - INTRODUCTION

GENERAL

The 16/24 Channel Multiplexer Module 40-630/632, which forms part of the System 40 PXI Programmable Switching
system. This module is provided in single mode or multi-mode congurations Single mode configuration is where the
multiplexer operates conventionally with a break-before-make action when a new channel is selected. Multi-mode
configuration is where the multiplexer selects more than one channel, but not at the same time.
Built-in Automatic Isolation Switching connects only the currently active multiplexer bank on to the analogue
common, thereby keeping capacitive loading and leakage currents in large multiplexer systems to a minimum.
Larger multiplexers may be constructed by Daisy Chaining the common signals from multiple PXI cards.
The screened version (40-630-021-S) is suitable for switching frequencies up to 100MHz. It may also be used with
low frequency signals where very good isolation and crosstalk performance is required.
Connections are made via a front panel SCSI 2 type 68 pin connector.
The Versatile Multiplexer Module 40-630/632 is provided in the following versions:
Single Mode
• Single 64 Channel Multiplexer 1 Pole (Part Number 40-630-022-64/1)
• Dual 32 Channel 1 Pole Multiplexer (Part Number 40-630-022-D/32/1)

SECTION 3 - INSTALLATION

Software Installation

First install the appropriate Pickering PXI switch card drivers by running the installer program Setup.exe, either
from the CD-ROM supplied, or by downloading the latest version from our website http://www.pickeringtest.com
- the recommended method. There are different versions of the Setup program to suit different Windows versions
and software environments. Setup is accompanied by a ReadMe file containing additional installation information.
A single installation covers all cards in the System 40, System 45 and System 50 ranges.
When installation completes, the installed drivers’ ReadMe file is offered for display. It can also be displayed later
using a shortcut on the Programs>>Pickering menu.
If you are not a LabVIEW user you should choose the “full” version, and once that has been installed run the
LabVIEW Runtime Engine installer via the shortcut on the Programs>>Pickering menu. In the absence of LabVIEW
the Runtime Engine is required to support the Pickering Test Panels application.

Hardware Installation

CAUTION

Electrostatic discharge can damage the components on the module. To avoid such damage in handling the board,
touch the anti-static bag to a metal part of the chassis before removing the board from the bag.
Ensure that there is adequate ventilation in accordance with the PXI Specification
The module should be installed in accordance with the following procedure:
1. Ensure that the system is turned OFF but still connected to mains so that it remains grounded.
2. Choose an appropriate slot in the rack.
3. Remove the blanking plate for the chosen slot.
4. Ensure that the injector/ejector handle is in its downward position. Align the module with the card guides on the
top and bottom of the slot.

CAUTION

Do not raise the injector/ejector handle whilst inserting the module. The module will not insert properly unless the
handle is in its downward position.
5. Hold the handle whilst slowly sliding the module into the card guides until the handle catches on the injector/
ejector rail (refer to Figure 3.1).
6. Raise the injector/ejector handle until the module firmly seats into the backplane. The front panel of the module
should be flush with the front panel of the chassis.
7. Screw the front panel of the module to the front panel mounting rail.
8. In a system employing MXI-3 to connect a desktop PC to a PXI chassis or to link multiple chassis, power-up the
system as follows:
a. For a system comprising a PC and one chassis, power up the chassis before powering up the PC.
b. For a system comprising more than one chassis, turn ON the last chassis in the system followed by the
penultimate, etc, and finally turn ON the PC or chassis containing the system controller.

Start the Test Panels application from the Programs>>Pickering>>PXI Utilities menu. If you are a LabVIEW user, run
“Test Panels (LabVIEW VI)”; if not, run “Test Panels (EXE)”. A selector panel will appear, listing all installed Pickering
PXI switch cards. Click on the card you wish to control, and a graphical control panel is presented allowing operation of
the card. Panels can be opened simultaneously for all the installed cards.

As an alternative to the Test Panels, the simple Terminal Monitor program PILMon (again on the
Programs>>Pickering>>PXI Utilities menu) allows access to all functions of Pickering switch cards through a
command-line interface. In PILMon, enter “HE” for help on it’s commands.
Please note that both the Test Panels and Terminal Monitor gain exclusive access to the cards, and so only one of
them can be operational at any time.

SECTION 4 - PROGRAMMING

System 40, System 45 and System 50 cards are supported by comprehensive Windows software drivers and can
also be programmed at register-level.
There are two separate Windows drivers, one accessing cards by Direct I/O and the other through VISA (Virtual
Instrument Software Architecture). Both are fully documented by ReadMe and HTML help files, accessible through
shortcuts on the Programs>>Pickering menu.
The following programming environments are supported for both drivers:
• Microsoft Visual Basic
• Microsoft Visual C++
• Borland C++
• National Instruments LabWindows/CVI
• National Instruments LabVIEW
Support for all these environments is included in the standard installation.
Please refer to the PXI Switching Programming Manual for complete programming information. This manual is
available on the Pickering Interfaces website at http://www.pickeringtest.com.

SECTION 6 - TROUBLESHOOTING

Installation Problems

The Plug & Play functionality of Pickering switch cards generally ensures trouble-free installation.
If you do experience any installation problems you should first ensure that all cards are properly seated in their slots.
Improperly mated cards may go undetected by the operating system, or may be detected as a card of an unknown
type. They can also cause the computer to freeze at various stages in the boot sequence.
If your system employs MXI-3 you should check the integrity of all MXI-3 links. When the system is powered up, and
during Windows start-up, you should expect to see periodic activity on the MXI-3 RX/TX (yellow) indicators, clearing
to leave only the PWR/LNK (green) LEDs illuminated. The RX/TX indicators should show activity when you attempt
to access a card.

Diagnostic Utility

The Pickering Diagnostic Utility (accessible through the Programs>>Pickering>>PXI Utilities menu) generates a
diagnostic report of the system’s PCI configuration, highlighting any potential configuration problems. Specific details
of all installed Pickering switch cards are included. All the installed Pickering switch cards should be listed in the
“Pilpxi information” section - if one or more cards is missing it may be possible to determine the reason by referring to
the PCI configuration dump contained in the report, but interpretation of this information is far from straightforward,
and the best course is to contact Pickering support: support@pickeringtest.com, if possible including a copy of the
diagnostic report.
In the “VISA information” section, if VISA is not installed it’s absence will be reported. This does not affect operation
using the Direct I/O driver, and is not a problem unless you wish to use VISA. VISA is a component of National
Instruments LabWindows/CVI and LabVIEW, or is available as a standalone environment.
If VISA is present and is of a sufficiently recent version, the section “Pipx40 information” should present a listing
similar to “Pilpxi information”.
Please note that the Diagnostic Utility cannot access cards if they are currently opened by some other application,
such as the Test Panels or Terminal Monitor.
The tables on the following pages help to identify faulty relays.

Functional Description

A functional block diagram is provided in Figure 7.2. The Versatile Multiplexer Module 40-630/632 is powered by a
+5V input via Compact PCI connector J1. The interface to the user test equipment is via the front panel mounted
68-way SCSI type connector, J2. The module comprises a PCB populated with single pole or two pole relays, or
single pole RF relays, depending on the module type. The relays are energised via control signals from relay drivers
U8 to U13. The relay drivers are addressed by PCI bridge U1 to output the required signal. Module configuration is
determined by hardwired links and data stored in EEPROM U7. PCI Bridge U1 is configured by EEPROM U2.
