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 System 10/20 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.
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
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.

The 20-610 Universal 352 Pin Multiplexer Module was the rst in
a new generation of very high density multiplexers from Pickering
Interfaces. One standard module offers a very large range of
switching possibilities plus extensive built in self-test.
Model 20-610 offers the very highest density multiplexing with 352
switch pins.
Universal Multiplexer - For Now & The Future
The 20-610 may be used for most general purpose multiplexer
requirements. The analogue common/s may be routed to the front
panel or, for large system implementation, to one of the internal
analogue buses. This versatility means that one multiplexer
module is suitable for many different applications.
Simple Internal Expansion to 10,000 Channels
Up to 2816 input channels can be accommodated in one System
20 Case, over 10,000 with multiple expansion cases.
Built-in Automatic Isolation Switching connects only the currently
active multiplexer switch bank, thereby keeping capacitive loading
and leakage currents in large multiplexer systems to a minimum.

Creating Larger Multiplexers
When more than one module is used to make up a multiplexer –
see diagram below, where seven modules are used to make up a
1232 channel 2-pole multiplexer – then all multiplexer units must
have the same internal address, the location of each module within
the multiplexer is given by its own bank address. Bank addresses
must start at 0 and should be contiguous.
If there is a problem with any of the modules used to make
up a large multiplexer then an error will be detected (use the
REPORT? query to discover the cause).
Analogue Bus
The analogue common can be routed (using internal jumpers)
out to either the front panel connectors or the internal analogue
bus. Routing to the front panel allows the user complete exibility,
routing to the internal analogue bus simplies large system
construction and ensures good signal isolation from external
interference.
The System 10/20 backplane features a shielded 24 pole analogue
bus. This would be used with a multiplexer constructed using more
than one module where the selected channel will be carried along
the backplane analogue bus.
Built-In RS-232 Port
The 20-610 also has a built in RS-232 port (9600 baud, XON/
XOFF, 8 bit, no parity). This is provided on a 4 pin Molex type
connector on the front panel. A separate adapter lead to allow use
with a standard 9 pin D-type is available. The RS-232 port allows
the module to be congured, controlled and monitored from any
RS-232 terminal. This can be a very versatile debugging aid.
