The 60-552 is a high density single pole matrix with a maximum
size of 64x64 suitable for signal routing in large ATE systems.
It can be expanded to produce larger matrix sizes, for instance,
two units can be linked to create a 128x64 matrix. Expansion is
made easy by the inclusion of front panel “Loop-Thru” connectors
for daisy-chaining the X or Y bus. Where a smaller matrix size is
required, 16x64, 24x64, 32x64, 40x64, 48x64 and 56x64 versions
are available.
The 60-552 can also be supplied in dual matrix formats of 8x64,
16x64, 24x64 and 32x64. In these congurations the chassis
contains two identical matrices which can be controlled separately.
The 60-552 is designed in accordance with the LXI Standard 1.4
and is supplied in a 1U high, full rack width case with 500mm
depth. It is programmable via the LAN interface using Pickering
Interfaces’ generic switch driver. Industry standard (W3C) web
browsers can be used to access and change conguration
information and provide access to the soft front panels.
The 60-552 is ideal for applications where a simple start-up
process is required and for applications requiring control over large
distances.

The 60-552 is a 1-pole matrix available in sizes between16x64 and 64x64 as well as dual and custom congurations.
The chassis contains an embedded processor assembly, power supply and two Base Boards. Each Base Board is
populated with a 8x64 matrix and, depending on the overall matrix size, a further six 8x64 matrix daughter cards
can be tted (three per Base Board). A fully populated chassis, with all boards tted has a matrix size of 64x64, the
minimum matrix size of 16x64 is achieved with Base Boards only. A full breakdown of the Base/Daughter Board
combinations for all the available 60-552 matrix congurations is shown in Figure 7-1. The matrix X and Y signals
routed on the Base Boards the front panel mounted connectors, the signals are also routed to X and Y Loop-Thru
connectors for expansion to other 60-552s.
Switch setting information for the matrix is sent from the Embedded Processor to the relay drivers on the Base
Boards and Matrix Daughter Boards via a Bridge Card. Programming information for the processor is sent to
the unit via the LAN interface from a remote computer using the unit’s unique Ethernet address. Programming
documentation for the unit as well as data for Pickering’s other LXI compatible switching products is stored in the
embedded processor and can be downloaded over the LAN interface. Status LEDs on the front of the chassis
indicate the condition of the unit and the LAN connection.

SECTION 2 - TECHNICAL DESCRIPTION
MATRIX EXPANSION
Example 1
The 60-552 may be easily expanded to larger matrix sizes by using the front panel X and Y “Loop-Thru” connectors.
The following illustrations show four 60-552-007 Single 64x64 matrices interconnected as a 128x128 matrix using
four 78-pin D-type female to female cables. Figure 2-2 shows the matrix schematic and Figure 2-3 shows how the
front panel connectors are cabled together. A suitable cable for interconnecting adjacent 60-552 units is the Pickering
40-970-078-0.25M.
It should be noted that when signals are routed through a network of matrices interconnected in this way, there will be
a slight degradation in performance. The overall bandwidth of the matrix will be reduced, and signals will experience
a certain amount of attenuation associated with the extra path resistance involved in routing through two or more
matrices and the interconnecting cabling.
