SECTION 3 - INSTALLATION
HARDWARE INSTALLATION
CAUTION
Electrostatic discharge can damage the components on the card. To avoid such damage in handling the card, touch
the anti-static bag to a metal part of the chassis before removing the card from the bag.
The card 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 free PCI slot in the host system.
3. Remove the blanking plate for the chosen slot and retain the xing screw.
4. Carefully remove the card from its anti-static bag and insert the card’s edge connector into the free slot in the
host system.
5. Ensure the card is fully inserted into the edge connector and the front panel is fully in contact with the back of
card aperture in the host chassis.
6. Use the xing screw to secure the front panel of the card to the host chassis’ mounting rail.
7. Replace the chassis cover(s).
7. Power-up the host system.

SECTION 3 - INSTALLATION
pickering
GENERAL PURPOSE REED RELAY MODULE 50-110/115-021/121
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 le 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 le 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.
TESTING OPERATION
After installation of the hardware 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.

GENERAL PURPOSE REED RELAY MODULE 50-110/115-021/121
SECTION 4 - PROGRAMMING GUIDE
PROGRAMMING OPTIONS FOR PICKERING INTERFACES PCI CARDS
Software drivers are supplied for Microsoft Windows XP/Vista/7 operating systems, with specic support for the
following development environments:
●Microsoft Visual Studio (VB, C++, C#)
●Borland C++
●National Instruments LabWindows/CVI
●National Instruments LabVIEW and LabVIEW RT
Windows drivers are supplied in the form of Dynamic Link Libraries, which should also be usable in any other
development environment that supports them.
Programming for PCI
A number of different Windows drivers are available to meet particular system requirements, and should none of
these be suitable there is also the option of register-level programming. Drivers are generally ‘universal’, handling all
models in the System 40, 45 and 50 ranges; however some models that are not compliant with the Ivi Swtch class
cannot be used with the pi40iv IVI driver. The pipx40 and Pilpxi drivers are also applicable to certain models in the
System 41 (PXI Instruments) range - see these drivers’ System 41 support list.
Please note that this documentation is available in its most up-to-date form as HTML help les, fully hyperlinked for
easy access - both pipx40 and Pilpxi documents are included in the Pipx40vpp software installation.
IVI Driver for Windows - pi40iv
The pi40iv IVI (Interchangeable Virtual Instrument) driver supports all Pickering Interfaces PXI switch cards that
are consistent with the Iviswtch class model - as are the great majority of cards in the System 40/45/50 ranges. It
integrates well with LabWindows/CVI and LabVIEW, and is fully compatible with Switch Executive. It is also usable
in general-purpose programming environments such as Visual C++ and Visual Basic.
Prior installation of the VISA and IviEngine from National Instruments are required for the correct installation and
operation of this driver.
VISA Driver for Windows - pipx40
The pipx40 driver conforms to the VISA (Virtual Instrument Software Architecture) standard for programmable
instrumentation. Instrument control environments such as LabVIEW and LabWindows/CVI are based on VISA, and
pipx40 support libraries are provided for them.
Prior installation of VISA from National Instruments is required for the operation of this driver.
Where VISA is available, pipx40 can also be used in general-purpose programming environments such as Visual
C++ and Visual Basic. When IVI is not a system requirement this driver will often yield faster operation than the
pi40iv driver.
Direct I/ODriver for Windows - Pilpxi
The Pilpxi driver accesses cards directly, without using the VISA software layer, while offering similar overall
functionality to pipx40. It is most commonly used in general-purpose programming environments such as Visual
C++ and Visual Basic. Operating speed of the VISA and Direct I/O drivers is generally comparable.

SECTION 4 - PROGRAMMING GUIDE
pickering
GENERAL PURPOSE REED RELAY MODULE 50-110/115-021/121
Register-level Programming
Where the supplied drivers are not suitable, register-level programming can be employed - for example:
●If the functionality of the supplied drivers does not meet the application requirements
●If security considerations demand full source-code for the application
●In development environments that have alternate mechanisms for accessing PCI bus
●For operating systems other than Windows
General Pickering Card Architecture
With most drivers, before programming a Pickering card it is important to understand the basic architecture of
Pickering cards.
The switches on a Pickering card are organized into logical sub-units, each sub-unit containing a set of objects of
similar type and use. These objects may be switches, digital outputs, digital inputs, resistors, power supplies etc,
depending on the nature of the specic card.
For example a simple matrix card will usually contain a single sub-unit containing the switches arranged in a
2-dimensional array. However a similar card with additional isolating relays connected to the matrix will contain
additional sub-units containing those isolation relays.
Low level drivers include functions to allow the programmer to query the card to ascertain the number of sub-units,
and the size and type of each sub-unit.
For full details of the driver functions available the programmer should refer to the documentation provided.

MODULE ARCHITECTURE
One sub-unit is used to control the module’s relays as shown below. Enabling a particular bit closes the C to A signal
path(s).
The Modules utilise up to 64 SPST or SPDT relays depending on the option. In the default state the relays are either
open circuit (SPST) or to the ‘B’ terminal (SPDT). Energising a particular relay creates a signal path between the ‘C’
and ‘A’ terminals. The relay module’s switching architectures are shown in their default state in the diagrams below:

Using pi40iv
The IVI driver has no special labelling for this card and treats the relays as an array of switches, labelling the
channels using com / nc / no labelling tags.
pi40iv_Connect(vi, “com1”, “no1”); // Connects chA1 to com 1
pi40iv_Disconnect(vi, “com1”, “n01”); // Disconnects chA1 from com 1
Reconnects chB1 to com 1
pi40iv_Connect(vi, “com1”, “no6”); // Connects chA6 to com 6
SPST and DPST versions use the simple com/ch labeling tags.
The IVI Switch driver specication contains no bulk setting capabilities.
Using PIPX40
setChannelState
ViUInt32 sub_unit = 1;
pipx40_setChannelState(vi, sub_unit, 1, VI_ON); // Connects chA1 to com1
pipx40_setChannelState(vi, sub_unit, 1, VI_OFF); // Disconnects chA1 from com1
Reconnects chB1 to com1
pipx40_setChannelState(vi, sub_unit, 6, VI_ON); // Connects chA6 to com6
setChannelPattern
// Sub-unit is 64 bits wide, so 2 ViUInt32 values are needed to hold the entire pattern
ViUInt32 data[2];
data[0] = 1; // Sets lowest bit to 1, chA1 to com1
pipx40_setChannelPattern( vi, sub_unit, data);
data[0] = 0x20; // Sets 6th bit, chA6 to com6
// All other relays are set to o
pipx40_setChannelPattern( vi, sub_unit, data);
PROGRAMMING THE MODULE
Here are some simple examples of using the drivers with the 50-110-121 (64 Channel SPDT) module.
Using PILPXI
To operate a relay the user could use the simple OpBit command or the WriteSub commands
OpBit
DWORD sub_unit = 1;
PIL_OpBit( card_num, sub_unit, 1, 1); // Connects channel A1 to com 1
PIL_OpBit( card_num, sub_unit, 1, 0); // Disconnects channel A1 from com 1
Reconnects channel B1 to com 1
PIL_OpBit( card_num, sub_unit, 6, 1); // Connects channel A6 to com 6
WriteSub
// Sub-unit is 64 bits wide, so 2 DWORDs are needed to hold the pattern
DWORD data[2];
data[0] = 1; // Sets lowest bit to 1, channel A1 to com 1
PIL_WriteSub( card_num, sub_unit, data);
data[0] = 0x20; // Sets 6th bit, channel A6 to com 6
// All other relays are set to o
PIL_WriteSub( card_num, sub_unit, data);
