50Ω SIGNAL TERMINATION SWITCHING
LOOP-THRU SWITCHING
The 60-770 is a family of integrated RF matrices suitable
for use up to 2.4 GHz in a 50 Ω transmission line system.
The matrix design permits any one Y input to be connected
to any one X input, allowing the concurrent connection
of 16 signal paths. All paths are bi-directional, so any
connection to be used as an input or an output.
The 60-770 can be supplied in a variety of configurations
based on Y axis sizes of 16 and X axis sizes of 8, 16, 24
and 32. The matrix is factory re-configurable up to the
maximum size of 32x16.
The matrix exhibits excellent RF characteristics. Unused
inputs are automatically terminated in 50 Ω to ensure that
VSWR effects do not impact crosstalk. Y signals are also
routed via isolation switches to Loop-Thru connections to
enable easy matrix expansion with minimal signal loss.
The 60-770 is contained in a 6U full rack width enclosure
and is controlled via an LXI compliant interface. The unit
can be manually controlled through any industry standard
(W3C) web browser using the built in web interface.
Remote control via the LXI Ethernet connection is provided
through Pickering Interfaces switch driver.
Pickering Interfaces can use the design methods applied to
60-770 to construct RF matrices with other architectures,
for more information contact your Pickering Interfaces
sales representative.

LXI 2.4GHz MATRIX 60-770
pickering SECTION 2 - TECHNICAL DESCRIPTION
SECTION 2 - TECHNICAL DESCRIPTION
The 60-770 is an RF matrix arranged in 32x16, 24x16 or 16x16 format under the control of an LXI interface designed
for the routing of signals with frequencies up to 2.4GHz. An overall block diagram for the unit is shown in Figure 2-1.
The 60-770 uses tree style multiplexers to create a matrix that can connect the Y axis inputs to any of the X outputs,
but only one Y connector can be connected to a specic X connector.
Example: Y1 can be connected to X1, Y2 to X2, X3 to Y3 ……X8 to Y8 at the same time. However, both X1
and X2 cannot be connected to Y1 at the same time.
The structure also means that a link between X axis connectors cannot be established.
Example: X1 cannot be connected to X2.
Throughout this manual, and in the soft front panel, the matrix is shown as crosspoints as shown in Figure 2-2. The
driver and soft front panel automatically take care of all the relay settings required to control the tree multiplexers
without the user understanding the internal architecture of the product. Showing the switches as a crosspoint matrix
provides a much simpler understanding of how to control the unit and to see what the soft front panel is doing.

SECTION 2 - TECHNICAL DESCRIPTION
The Bridge Board is mounted on the Embedded Processor assembly and forms the interface between the
processor’s PCI bus and the serial data stream required for controlling the relay drivers. The serial data is fed from
the Bridge Board to Distribution Boards, from here the serial data, as well as voltage rails from the Power Supply,
are distributed to the relay drivers in the different sections of the switching matrix. The external X and Y connections
of the matrix are accessible via 50Ω SMA sockets on the front panel of the chassis
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.

pickering SECTION 3 - INSTALLATION
HARDWARE INSTALLATION
The 60-770 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 60-770 relies upon forced air cooling for the power supply, processor and relay circuit boards. An internal fan
draws air through slots in the side extrusions of the chassis and expels air through a vent 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 Figure 3-1.
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 overleaf.
The 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 60-770 RF 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 3-3.
The current IP address setting of the 60-770 is indicated on an LCD display on the rear panel of the chassis.

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).
