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.

WARNING - DANGER OF ELECTRIC SHOCK SYMBOL

This module may contain hazardous voltages. Before removing the module from the rack remove all

supplies and disconnect user I/O signals.

Unused slots in the host chassis are populated with blanking plates to prevent access to user I/O

signals that may be present. Blanking panels are available to order from Pickering in a variety of

slot widths. 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 module must not be used for the switching of Mains Circuits. For the switching of voltages up

to the module’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.

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.

CAUTION - PRODUCT DOCUMENTATION SYMBOL

Suitably qualied & trained users should ensure that the accompanying documentation is fully read

and understood before attempting to install or operate the product.

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.

Model

No. Conﬁguration Application

40-735 Single 36 channel or Dual 18

1 Gb Ethernet, AFDX,

BroadR-Reach, LVDS,

USB, RS232

40-737 Single 8:1 or 16:1 differential

pair and power USB1, USB2

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.

Other applications include the switching of

telephone cabling or the routing of LVDS, RS232

and USB serial interface signals.

The design uses long life electro-mechanical

relays characterized for use in telephony.
