WARNINGS AND CAUTIONS
WARNING - HAZARDOUS ENVIRONMENTS SYMBOL
This product is not specically designed for use in hazardous environments, for example in explosive
atmospheres. If the product is to be used in hazardous environments we recommend that the user
ensures suitable protective measures are taken.
!
CAUTION - HANDLING OF ELECTROSTATIC-SENSITIVE DEVICES SYMBOL
Certain semiconductor devices used in this equipment are liable to damage due to static voltage.
Observe the following precautions when handling these devices in their unterminated state, or
sub-assemblies containing these devices:
1. Persons removing sub-assemblies from equipment using these devices must be earthed by a
wrist strap and a resistor at the point provided on the equipment.
2. Soldering irons used during the repair operations must be low voltage types with earthed tips and
isolated from the mains voltage by a double insulated transformer.
3. Outer clothing worn must be unable to generate static charges.
4. Printed Circuit Boards (PCBs) tted with these devices must be stored and transported in
anti-static bags.
WARNING - DANGER OF ELECTRIC SHOCK SYMBOL
This card may contain hazardous voltages. Before removing the card from the chassis remove all
supplies and disconnect user I/O signals.
Unused slots in the PC chassis are populated with blanking plates to prevent access to user I/O
signals that may be present. . If the product is not used in this manner for example by using an
extender card then additional care must be taken to avoid contact with exposed signals.
Not to be used in safety critical circuits, refer to the Pickering Interfaces’ terms & conditions of sale.
This card must not be used for the switching of Mains Circuits. For the switching of voltages up to
the card’s full specication, Secondary Circuit power supplies and the Device Under Test must be
fully isolated from the Mains Circuit and the safety earth.
The host chassis must be correctly installed and be connected to mains or factory safety ground,
please refer to your chassis installation manual.
Diagram Showing Separation Between The Mains Circuit and Secondary Circuit / DUT
For the purposes of this document, a Mains Circuit is an installation classied as Overvoltage
Category II up to 300V. Separation between the Secondary Circuit and Mains Circuit is achieved
by a transformer in which the primary windings are separated from the secondary windings by
reinforced insulation, double insulation, or a screen connected to the protective conductor terminal.

SAFETY INSTRUCTIONS
SAFETY INSTRUCTIONS
All cleaning and servicing requires the equipment to be isolated and disconnected from the power source and user I/O
signals (refer to the Maintenance Section).
• Appropriate manual handling procedures should be followed as dictated by the weight of the individual module or
the combined weight of the modules & chassis.
• Should a fault occur with the module or chassis, immediately isolate and disconnect the incoming power to the
chassis and the user I/O signals.
• Ensure the equipment is installed, operated and maintained by trained and authorised personnel.
• For suitably equipped products in the event of an emergency press the red “emergency stop” button situated on
the front of the unit.

The 50-295A is a programmable resistor card with up
to 18-channels of 8-bit resolution resistor chains in a
single PCI slot. The flexible architecture allows the card
to be supplied with 12-bit, 16-bit or 24-bit resolution for
applications requiring finer resolution, greater resistance
range or higher channel count. The card is ideal for
simulating sensors for control and management systems
under test, allowing the user to verify responses in design
verification or manufacturing test applications.
The 50-296A version of the card is configured as a
potentiometers with two end connections and a wiper for
simulating adjustable components.
Versions with other resistor values can be provided for
specific applications. The resistor chains include an offset
resistor that can be used to set the minimum value.
Requests for these versions can be entered on a simple
web based form from the Pickering Interfaces web site,
allowing users a quick and easy way of obtaining a
quotation.
The card is available in a variety of densities that allow the
user to select the most appropriate solution in terms of
density and cost for an application. The card’s high channel
count enables large systems to be simulated with minimal
PCI slot occupancy.
All switches are instrument grade reed relays with low
thermal offset voltage to ensure accurate operation under
all conditions and a long service life.
To give maximum accuracy each resistor chain has
on-board E2PROM, this allows accurate calibration data to
be recorded.
The card is supplied with VISA drivers and a soft front
panel.

FUNCTIONAL DESCRIPTION
A functional block diagram is provided in Figure 2.1. Figures 2.2 and 2.3 provide examples of potentiometer chain
schematic diagrams for the 50-296A-121-9/8 version of the card. The Programmable Potentiometer Card is powered
by +5V inputs via the edge connector. The interface to the user test equipment is via the front panel mounted 37-pin
D-type connector, J2. The card comprises two PCBs populated with resistor chains which are switched via single
pole relays. The two PCBs are connected via a plug and socket connector arrangement. The relays are energised
via control signals from relay drivers which are addressed by PCI bridge U1, via the control logic comprising U3 to
U6, to output the required signal. Card conguration is determined by hardwired links and data stored in EEPROM
U7 PCI Bridge U1 is congured by EEPROM U2.
Each resistor chain includes an offset resistor that can be used to set the minimum resistance value.

PREOPERATION CHECKS (UNPACKING)
1. Check the card for transport damage and report any damage immediately to Pickering Interfaces.
Do not attempt to install the product if any damage is evident.
2. Position the PC chassis relative to any other equipment the card(s) will connect with. Ensure the chassis is
not connected to the electrical supply.
3. Ensure that the designated area for the chassis containing the card(s) is of at and solid construction to
withstand and support the total weight of the PC Chassis and cards.
SECTION 3 - INSTALLATION
!
Refer to the Warnings and Cautions at the front of this manual
Modular products require installation in a suitable chassis. The card is designed for indoor use only.

SECTION 3 - INSTALLATION
SOFTWARE INSTALLATION
First install the appropriate Pickering PCI switch card drivers by running the installer program Setup.exe (provided
in a compressed zip le), either from the CD-ROM supplied, or by downloading the latest version from our website
pickeringtest.com - the recommended method. 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.

HARDWARE INSTALLATION
ELECTRICAL CONNECTION (PC CHASSIS)
1. The PCI card must be electrically installed in accordance with local regional electrical codes by a qualied
engineer.
2. The PC chassis must be grounded.
Electrostatic discharge can damage the components on the card and in the chassis. To avoid such damage
when handling the products refer to page VII.
Ensure that there is adequate ventilation.
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 (refer to Figure 3.1).
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).
8. Power-up the host system.
