The 40-736 is designed specifically for multiplexing or
demultiplexing differential signal pairs having controlled
100 Ω impedance. The multiplexer can be configured under
software control to have single 32, dual 16 or quad 8 signal
pair switching. The dual and quad versions are particularly
suited for switching AFDX, Ethernet and BroadR-Reach links.
The 40-736 is capable of switching 1 Gb Ethernet signals
and the design includes a switching network that simplifies
the swapping of Tx and Rx pairs to simulate the effect of
crossover cables.
The module is ideal for testing multiple
devices that use serial interfaces, allowing one
target device from many to be selected. The
design is bi-directional and can be used as a
multiplexer or de-multiplexer with no impact
on performance. The module is compatible with
Power Over Ethernet.

FUNCTIONAL DESCRIPTION
A functional block diagram is provided in Figure 2.1. The Data Comms Multiplexer Module is powered by +3.3V and
+5V inputs via Compact PCI connector J1. The interface to the user test equipment is via the front panel mounted
78-pin D-type connector, J2. The module comprises a PCB populated with +5V two pole relays congured as four
2-pole 8 to 1 multiplexers, two 2- pole changeover switches, and a switching network for interconnecting the four
multiplexers. The relays are energised via control signals from relay drivers U50, U51 and U52. Each relay driver is
loaded with serial data from PCI bridge U1 via isolation devices U53 and U54, to output the required signal. Module
conguration is determined by data stored in Serial EPROM U3. PCI Bridge U1 is congured by Flash EPROM U2.
Refer to Figure 2.2 for a detailed switching diagram for the Data Comms MUX, and Figures 2.3 and 2.4 show the
signal allocations for the module when used with the RJ45 and USB interface boards respectively.

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
!
Refer to the Warnings and Cautions at the front of this manual
Modular products require installation in a suitable PXI/LXI chassis. The module is designed for indoor use only.

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.
