The 65-223 is a modular matrix platform that provides a large
reed relay matrix solution with 1 A current carrying capacity on all
Y paths.
Matrices are created by populating the 65-200 chassis with
plug-in modules that provide access to the X and Y axis on 200-
pin LFH connectors. The chassis is capable of supporting matrices
with a Y axis size of 8 and X axis sizes up to 768 in increments of
64. Users can specify as many or as few plug-in modules as they
require and can field upgrade the chassis to extend the matrix.
The chassis supports up to 6 plug-in modules. These can be with
or without direct Y bus access and are loaded into the chassis
via the front panel, greatly improving flexibility and ease of
maintenance.
Analog Buses
Each plug-in is a single or dual 64x8 sub matrix with the ability to
connect its Y axis to one of six analog buses. This provides a high
degree of flexibility in configuring the matrix. The analog buses
can be used to maximize bandwidth by disconnecting unused stub
matrices from the used bus, or it can be used to divide the 65-223
into six independent matrices whose size can be set by the user
in increments of 64 X connections. For example, six independent
banks of 128x8 matrix.
Simplified Diagram For 65-223
Configured as a 768x8 Matrix
Built-In Relay Self-Test - BIRST
The BIRST facility provides a quick and simple way of finding
relay failures. No test equipment is required, simply un-plug the
user connectors, launch the BIRST application and the tool will
run a diagnostic test that will find all relays with faulty contacts.
For more information go to: pickeringtest.com/birst
Supported by eBIRST
The matrix is also supported by our eBIRST test tools. These tools
simplify switching fault-finding by quickly testing the system and
graphically identifying the faulty relay.
For more information go to: pickeringtest.com/ebirst
Cooling for the 65-200 is provided by rear fans and front air
intakes ensuring no wasted space when the chassis is rack
mounted. The cooling system is adaptive, ensuring acoustic noise
is minimised when used in quiet laboratory environments and low
load conditions.
Configuring the Matrix
To select the parts that you need to create a matrix simply:
• Specify a 65-200-002 Modular Matrix Chassis.
• Add Matrix Plug-in Modules with direct Y access as required.
• Add Matrix Plug-in Modules without direct Y access as
required.
Both styles of plug-in module have options for single or dual 64x8
configurations, with six analog buses.

Overview
65-223 matrix
configurations range
between 64x8 and 768x8.
The overall matrix size can
be altered by the addition or
removal of plug-in modules.
The 65-223 plug-in modules can be
supplied as a single or dual 64x8 matrix
with or without front panel access to the
Y-bus. Also, 6 analog buses are provided,
each with eight connections which can be
routed via isolation relays to the Y-bus of
any 64x8 sub-matrix that makes up the
overall 65-223 matrix.
The 64x8 matrices of the 65-223 plug-in
modules are made up from four 32x4 matrix
plug-on modules. These use Pickering
high density instrument grade ruthenium
reed relays for maximum reliability and
performance. The isolation relays that
connect the analog bus to the matrix are
also on replaceable plug-on modules.
The modular architecture of the 65-223
allows easy maintenance and repair.

Overview
Sequencing Service and Triggering
The Sequencing service provides the user with the ability
to set a series of pre-determined sequences on an LXI
instrument. These sequences can be triggered by software
or one of the sixteen software configurable open collector
triggers.
As the operations are grouped together, it will minimize
the number of control transactions required to achieve
a composite change of target switch state, condensing
multiple operations in a single sub unit into a single
operation, thus reducing the overall system switch settling
time.
For example, if a user wants to operate X1-Y1, X4-Y1, X2-Y2,
in the first sequence, only one operation, and so delay, will
be used.
Additionally, as the switch state sequences are stored
within the LXI controller itself, the burden on the Host CPU
and Ethernet traffic is greatly reduced, and so the overall
system latency is also reduced.
Speed of Operation Diagram For The 65-223
Note: These are estimated figures, PC processing and Ethernet transmission times
may vary depending upon the overall system setup and load.
This unit features a software reset line which provides
the ability for a user supplied reset to be applied to the
unit, triggering a software reset of the relays, returning
all relays in the unit to their default state. There is also a
software fault line available that will be triggered if there
is any error detected within the unit. Please note that
while these reset and fault lines use dedicated physical
connections to the unit, they are software control lines and
as such should not be used for safety interlocks etc.
Speed of Operation
Speed of Operation can be important when defining
systems for test applications, therefore it can be beneficial
to understand all the necessary overhead delays
associated with a switch operation.
If we consider a single relay / block relay operation, it
can be considered to be a combination of five discrete
operations: PC Processing, Ethernet Latency, LXI
Processing / Virtualisation, Serial Loop Transmission and
Relay Settling.
A representation of these processes can be seen in the
diagram below.

SECTION 2 - TECHNICAL DESCRIPTION
FUNCTIONAL DESCRIPTION
The 65-223 is a modular switching system which is designed to provide a high density exible matrix solution by the
addition of plugin modules. The component parts are as follows:
• The modular 65-200-001 chassis is the basis of the system and consists of a backplane, power supply and
controller card housed in a 2U rack mountable chassis. The backplane is capable of hosting up to 6 plugin
modules and distributes power, contol signals and matrix Y connections between the plugins. The controller
card is based on an embedded processor and provides contol and management of the matrix via an LXI
compliant LAN interface. A basic block diagram is shown in Figure 2-1.
• The 65-223-001 is a dual 64x8 matrix plugin module with 6 separate analog buses. The analog buses are
routed to the front panel, the backplane and are connected to the Y-bus of the matrix via isolation realys. User
access to the matrix X-bus and analog buses is via two 200-pin LFH connectors on the front panel. A switching
diagram for the module is shown in Figure 2-2.
• The 65-223-101 is the same as the 65-223-001 but has no front panel access to the analog buses. See
Figure 2-3.
• The 65-223-002 is the same as the 65-223-001 but is congured as a single 64x8 matrix and has one 200-pin
LFH connector on the front panel. See Figure 2-4.
• The 65-223-102 is the same as the 65-223-002 but has no front panel access to the analog buses. See
Figure 2-5.
