Installing and use of XPRS-PX-X1

1. Introduction

The XPRS-PX-X1 connects with one of our XRPS-HOST-.. cards, and allows using of PCI Express -x1 type peripheral cards outside of a computer system.

The image shows XPRS-PX-X1 product, cables coming from XRPS-HOST-.. card, and one PCI Express -x1 type peripheral card.

2. Preliminary step

Based on the computer system one preliminary step is installing of a XPRS-HOST-.. card:
- xprs-host-dt on a PCI Express desktop system
- or, xprs-host-ec on a notebook system with an ExpressCard slot

3. Assembly of XPRS-PX-X1

There are 2 ways to connect the 2 cables to the connectors on XPRS-PX-X1.

Make sure that the XPRS-HOST-.. card is inserted, and the host computer system is powered on.

The image above shows the wrong way of connecting the cables to the connectors - the onboard LED is not lit, the LED is not on.
In such case remove both cables, switch positions, and plug to the other connectors.

The image below shows the right way - the onboard LED is lit, the LED is on.

4. Insert / remove of peripheral cards

When the host system is a notebook, and the operating system supports ExpressCard slots, you can dynamically insert/remove PCI Express -x1 type card on XPRS-PX-X1.

When the host system is a desktop, or the operating system does not support hot insert/ remove of PCI Express based peripherals you need to:
- power off host system
- mount XPRS-HOST-.. in the system
- connect cables to XPRS-PX-X1 - in the proper way
- mount PCI Express -x1 type card
- power on host system

ARSTech Enumerator provides indication of events, and additional software support for hot insert/ remove.

5. Additional ways of use

5.1. Adding power

PCI Express cards require 3.3V for powering, and optionally may use also +12V for powering.

If a peripheral card uses 3.3V with low current consumption, the card may be powered directly through the cables.

If a peripheral card uses 3.3V with low current consumption, and needs +12V with current consumption of up to 50mA, you can add the PWR-M1 power module.

Specific cards may have high current consumption, beyond the amount of current provided through the cables.

In such case, you can connect our PWR-3V product to supply high current on 3.3V, or PWR-12V product, to supply high current on 12V.

The power jumpers positions may need to be moved - please check the User's Guide .pdf, the chapter on XPRS-PX-X1, for details.

5.2. Putting in an enclosure

The XPRS-PX-X1 together with the PCI Express -x1 type card may be mounted in an enclosure.

The image below shows putting the cards in our ISA-PCI-B1 enclosure.
