Switching diagram for the
40-737-901 8:1 USB Multiplexer
(relays are shown in their default position)
The 40-737 is an 8:1 or 16:1 multiplexer for switching data signals
and is specifically designed for routing USB. The data paths are
2-pole differential pairs as defined by the USB standard. The
multiplexer signal pairs have a controlled differential impedance
and the USB power paths have a common negative and a
switched positive. All paths are designed for minimum loss.
The common of the 8:1 multiplexer is via a front panel mounted
USB type B socket, and the eight channels are via USB type
A sockets. The 16:1 multiplexer has a male 78-pin D-type
connector for all signals and, using an interface board (40-965-
909), standard USB cables can be connected. Both multiplexer
versions are capable of switching USB1 or USB2.
The module is ideal for testing multiple USB devices, allowing
one target device to be selected from many. The design is
bi-directional allowing use as a multiplexer or de-multiplexer
with no impact on performance. Long life electro-mechanical
relays characterized for telephony are used.

pickering SECTION 2 - TECHNICAL DESCRIPTION
SECTION 2 - TECHNICAL DESCRIPTION
FUNCTIONAL DESCRIPTION
A functional block diagram is provided in Figure 2.1. The USB Multiplexer Module is powered by +12V and +5V
inputs via Compact PCI connector J1. For the 8-channel version, the interface to the user’s equipment is via the
front panel mounted USB type B connector for the MUX common, and USB type A connectors for each of the 8
MUX channels. For the 16-channel version, all USB signals are via 78-pin male D-type connector on the front panel.
The 8-channel comprises a mother PCB containing the PCI bridge and control logic, and a daughter PCB populated
with 15 relays congured as a 2-pole 8:1 tree multiplexer for the USB differential data paths and a 1-pole 8:1
conventional multiplexer for the USB power paths. The 16-channel has only a mother board populated with the
PCI bridge, control logic and 31 relays congured as a 2-pole 16:1 tree multiplexer for data and a 1-pole 16:1
conventional multiplexer for power. The relays are energised via control signals from a relay driver device. The relay
driver is addressed by PCI bridge U1, via output registers, to output the required signal. PCI Bridge U1 is congured
by EEPROM U2.
Default Switch State
The default state of the multiplexer is as shown in Figures 2.2 and 2.3 overleaf. It should be noted; at power up, and
following the clearing of the state of the subunits, that the data-paths default to channel 8 (40-737-901) or channel
16 (40-737-001) and the power-path defaults to an off state.

PREOPERATION CHECKS (UNPACKING)
1. Check the module 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 chassis relative to any other equipment the module(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 module is of at and solid construction to
withstand and support the combined weight of the module(s) and chassis.
SECTION 3 - INSTALLATION

SECTION 3 - INSTALLATION
SOFTWARE INSTALLATION
First install the appropriate Pickering PXI 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 (CHASSIS)
1. The chassis must be electrically installed in accordance with local regional electrical codes by a qualied
engineer.
2. The chassis must be grounded.
Electrostatic discharge can damage the components on the module. To avoid such damage in handling the
board refer to page VII.
Ensure that there is adequate ventilation.
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.
Do not raise the injector/ejector handle whilst inserting the module as the module will not insert properly.
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 rmly seats into the backplane. The front panel of the
module should be ush with the front panel of the chassis.
7. Secure the front panel of the module using both screws to the chassis front panel mounting rails.
8. In a system employing a remote control interface to connect an external controller to a PXI chassis or to link
multiple chassis, power-up the system as follows:
a. For a system comprising an external controller and one chassis, power up the chassis before powering up
the external controller.
b. For a system comprising more than one chassis, turn ON the last chassis in the system followed by the
penultimate, etc, and nally turn ON the external controller or chassis containing the system controller.
9. For Pickering Interfaces modular LXI installation there is no requirement to use any particular power up
sequence.
