The BIRST facility provides a quick and simple way of nding 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 nd all relays with faulty contacts.
For more information go to: pickeringtest.com/birst
Supported by
eBIRST
In addition to BIRST, these matrices are also supported by eBIRST.

For more information go to: pickeringtest.com/ebirst
The 60-550 is a high density single pole 512x8 matrix suitable for
signal routing in large ATE systems. It is easily expanded to produce
larger sizes, for example, two units can be linked to create a 1024x8
matrix. The 60-551 has an identical architecture to the 60-550 but has
a 4-wire instead of an 8-wire Y-bus.
The matrix is constructed from 64x8 or 64x4 sub assemblies,
permitting it to be supplied in a variety of sizes from 128 to 512 X
connections in increments of 64.
Dual Analog Bus
The Y connections of the sub-matrices can be connected to one of two
analog buses (Dual Analog Bus). These can be used to maximize
bandwidth by disconnecting unused stub matrices from the bus
in use. They also provide conguration exibility by giving the
potential to divide the 60-550/551 into two independent matrices
whose size can be set by the user in increments of 64 X connections.
The 60-550/551 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 60-550/551 is ideal for applications where a simple start-up is
required and for applications requiring control over large distances.

LXI HIGH DENSITY EMR MATRIX 60-550/551
pickering SECTION 2 - TECHNICAL DESCRIPTION
SECTION 2 - TECHNICAL DESCRIPTION
The 60-550 is a 1-pole matrix available in sizes between 128x8 and 512x8. The chassis contains an embedded
processor assembly, a power supply and a left and a right Base Board/Daughter Board combination. Each Base
Board or Daughter Board is populated with a 64x8 matrix and, in its smallest matrix size, the 60-550 is tted with
only a left Base Board (designated “A”) with one Daughter Board mounted on top. A 256x8 matrix has a left and a
right “A” Base Boards, each mounted with Daughter Boards. A 384x8 matrix has a further Base Board (designated
“B”) mounted with a third Daughter Board which in turn is mounted above the left Daughter/Base Board combination.
Fully populated, the 60-550 has a second “B” Base Board mounted with a fourth Daughter Boards tted above the
right Base/Daughter Board combination. A full breakdown of the Base/Daughter Board combinations for all the
available congurations is shown in Figure 8-3. The 60-551 is essentially the same as the 60-550, but with each
Base Board and Daughter Board populated as a 64x4 matrix.
The matrix X signals are routed on the “A” and “B” Base Boards to front panel mounted 78-pin D-type connectors.
The Y bus signals are linked between the two matrix card stacks via a connectors on the two lower “A” Base Boards.
External connection to the Y bus is via the two 78-pin D-type connectors on the left-hand “A” Base Board.
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. An overall functional diagram is shown in Figure 2-1 below.

MATRIX ARCHITECTURE
The following diagrams show the architecture of the 60-550 and 60-551 matrices in more detail than the basic diagram
on Page 1-1. The 60-550 consists of up to eight 64x8 sub-matrices linked by two analog buses - see Figure 2-2.
Isolation/selection switches determine wether the Y connections of a sub-matrix are connected to Bus A, Bus B or
isolated from the other sub-matrices. The connectors for sub-matrix cards 1 & 2 route the analog bus signals A &
B to the front panel. The 60-551 has the same topology but with 64x4 sub-matrices and 4-wire analog buses - see
Figure 2-3.

HARDWARE INSTALLATION
The 60-550/551 may be mounted on a desk top or tted into a standard 19 inch rack (rack mounting anges are
supplied with the device and can be tted to either side of the front panel). When tting into a rack it is important
to provide adequate support using side brackets or runners, the mounting holes in the front panel anges
are designed only for securing the device in the rack and must NOT be used to support the weight of the
whole device.
The 60-550/551 relies upon forced air cooling for the power supply, processor and relay circuit boards. Internal
fans draw air through slots in the front panel of the chassis and expel air through vents on the rear panel. When
positioning the device, make sure that there is adequate clearance to allow unrestricted air ow through these vents.
The locations of the air intakes and outlets are shown in Figures 3-1 and 3-2..
Power is supplied to the rear of the device using a standard IEC power lead and the power on/off switch is located
next to the power inlet socket. The device is supplied with a suitable Earthed mains power lead, If a different lead
is used it is important to ensure that an adequate Earth connection is present. When mounted in a rack, provision
should be made to allow access to the rear of the device. This is to enable the operation of the power on/off switch
and the LAN Reset button. The rear panel layout is shown below.
The High Density Matrix is controlled by the host computer via an Ethernet interface. The RJ45 socket on the rear
of the device can be connected to a hub or switch via an Ethernet cable to allow control over a local area or wide
area network. Alternatively a crossover Ethernet cable can be used to connect the device to a laptop PC and local
control can be carried out isolated from a network. The IP address of the unit has to be manually or automatically
congured before it can be used on a network, please refer to “Setting the IP Address” in the following section and
the “LXI Getting Started Guide” document to carry out this process.

SETTING THE IP ADDRESS
To use the 60-550/551 High Density Matrix over a LAN connection it should be set up and congured as described
in the “LXI Getting Started Guide” document.
If the IP address is to be set manually and before connecting to a network, contact your IT department so they can
give you the correct settings for:
• IP Address
• Subnet Mask
• Default Gateway
• DNS Server(s)
Once you have the required information, the IP conguration window is used to manually set the IP address. This is
shown in Figure 3-4.
The current IP address setting of the 60-550/551 is indicated on an LCD display on the rear panel of the chassis.
Figure 3-2. Front view of the High Density EMR Matrix showing the intake slots for cooling air
Incorrect setting will result in a loss of communication and may also be indicated by a red LAN LED on the front
panel. If this does occur press and hold the LAN Reset button on the back panel of the device for a full factory reset
(see Section 6 “Troubleshooting” for details).
