2 General Description
2.1 Introduction
The PCI Express Cable Extender is designed for support debugging and verification x1 PCI
express boards (referred as UUT, Units-Under-Test). PCI express Cable Extender (Cable
Extender) utilizes the modern “PCI express via Cable technology”. It connects to the host
computer via standard CAT6 data cable, 10 pin flat control cable and x1 PCI express, MiniPCI
express or ExpressCard® interface board.
The Cable Extender uses a bus switch to connect/disconnect the UUT PCI express board from the
host computer without it shutting down. This flexibility minimizes the testing time, protects the
host computer from damage and what is new make it possible to move noisy computer out of the
way.
Figure 1: PCI express Cable Extenders SKU-016-3x
The Cable Extender supports two ways of feeding power to the UUT: internal, when power
coming via flat cable from host computer and external, when power coming from external power
supply. The external power supply has to provide +12V/7A power voltage to satisfy all PCI
express needs.
The Cable Extender fully protects UUT and host computer from damage by monitoring and
limiting the voltage and current supplied to the UUT. Extender measured in real-time the current
value on the 12V power and 3.3V power and visualize it on the three 7-segment indicator. The
current value can be transmitted to computer via USB link for current monitoring and logging.
The PCI Express Cable Extender has additional support tabs for the add-in PCI express boards
(UUT) stabilization (US. Patent: 7,255,570). Stabilization PCI express boards that has to be
plugged into Cable Extender makes it possible to rotate UUT during debugging.

3 Requirements/Features
3.1 Power/Interface Signals
•Indication of UUT powers +3.3V, +12V (green LED with label “PWR”)
•Indication of incoming +12V power from external power supply or from host computer (green
LED)
•Indication overload condition (red LED with label “FAIL”), PCI express reset signal status
(red LED with label “RST”)
•Indication of present UUT (blue LED with label “PRSNT”)
•Overloading Protection (OLP) on the UUT +3.3V and +12V supplies
•Support powering UUT from external power supply (in case that external psu connected to
extender) as well as from host computer
•JTAG connector for easy access to the PCI expresses JTAG signals. Enable plug-in JTAG
emulators or AMFELTEC Easy Loader™ for programming/ loading CPLD/FPGA on the
UUT during testing/production cycle.
•Two pin ground jumper for easy using testing equipment that needs ground connection (like
voltmeter, oscilloscope, logic analyzer etc)

•Hot-swap support
3.2 Debugging Support
•Allow access to the UUT PCI Express bus JTAG signals
•Ground jumper for plug in test equipment probes
•Support tabs for mechanical stabilization UUT, allow rotate the Cable Extender with UUT
during operation for easy access to the any part/signal of UUT (Figure 3)
•Double set of LEDs on top and bottom of the Cable Extender to provide status during
debugging of the top or bottom side of the UUT

3.3 Software
AMFELTEC Corp. provides software for supporting hot-swap functionality. The software allows
to save and restore the PCI Express configuration for UUT device (refer to eX10 Software Manual
for more details).
Installation

4 Installation
4.1 Hardware
Following steps provide the exact sequence need to be followed in order to properly install the
PCI Express Cable Extender product from AMFELTEC Corp.:
•Turn OFF host computer before installation. Remove the chassis cover from host computer.
•Locate an unused PCI express slot and remove the corresponding slot cover from computer
chassis.
•Plug-in the x1 PCI express Host board to selected PCI express slot and attached its bracket to
the computer chassis with a screw.
•In case of MiniPCI express Host board, install it in MiniPCI express circuit on the Host
computer motherboard
•Put the chassis cover back on the computer.
•In case ExpressCard® - just insert ExpressCard interface board into the ExpressCard® slot on
the laptop.
•Connect the CAT6 cable and flat cable to PCI express or ExpressCard® interface board and
the other end to the connectors on the PCI Express Cable Extender.
•In case that it is necessary to use external power supply for powering UUT the external power
supply has to be plugged to the Cable Extender.
•In case ExpressCard® Host board, Extender has to be always powered from the external
power supply.
•Set SW1 switch into position ON.
•Plug in UUT to the Cable Extender.
•Turn ON host computer.
•The “PRSNT” LED (blue) has to be ON, the “PWR” LEDs have to be ON, the FAIL and
RST LEDs (red) have to be OFF.
4.2 Software
PCI Express Cable Extender doesn’t require any software/device driver for operation. You will
only need to install the software provided by Amfeltec Corp. in order to use the hot-swap feature.
Please refer to eX10 Suite Manual for software installation details.
Operation

5 Operation
5.1 Hot-Swap support
Perform hot swapping with a certain degree of carefulness. Remember that PCI configuration
won’t be loaded or automatically updated on insertion of a new UUT device unless you use the
supplied HOT SWAP software to reload the UUT’s PCI configuration.
5.1.1 Remove UUT Device
The following steps describe the sequence for removing UUT device:
1. Save UUT PCI configuration into a file (refer to Software Manual for more details).
2. Unload all device drivers associated with the UUT.
3. Set the switch SW1 to “OFF” (disable power).
Now, you can remove UUT device from the PCI Express connector.
5.1.2 Install UUT Device
The following steps describe the sequence for installing UUT device back to the system:
1. Plug in UUT device into the PCI express connector.
2. Set the switch SW1 to “ON” (enable power).
3. Restore PCI configuration for the UUT device.
Now, the UUT device is ready for use.
