Introduction
Dow-Key Microwave, a leader in the design and manufacture of switching
products, acquired its Matrix line in 1999. Since that time, the line has
expanded to include both standard and custom matrices supporting the
aerospace, military and communication industries for both signal routing and
ATE applications. All Dow-Key matrices incorporate Control Area Network
bus (CANbus) serial communication in their design. This technology allows
for fast system integration and flexibility for today’s complex system requirements. Although this brochure only showcases a few established designs,
Dow-Key welcomes inquiries for all matrix applications.
Internal CANbus-based control technology includes the following features:
• Self-identification and configuration of all switchable devices
• Multiple control interfaces
• Field upgradeable operating software.
• Flexibility to add more than 200 switchable devices to the system.
As an option, the switch matrix can provide signal conditioning by incorporating amplifiers, filters, attenuators, couplers, and other components.

Open Control Architecture
A considerable number of
external CANbus devices
can be added to the Matrix.
During system start up, the
internal controller identifies
CANbus devices and initiates
control via communication
interfaces.

Reconfigurable Switch Matrix (RMS)
Models:
4700-GPIB
4700-ENET
4700-EWEB
Dow-Key’s Reconfigurable Matrix
System (RMS) is offered as a
solution for the new generation
of reconfigurable and expandable
state-of-the-art (ATE) test systems. It provides
the user with the capability to configure the interconnection of all internal components and add additional components to
a test system when needed, thereby extending its functionality.
While the internal control interface is CANbus-based, the RMS software
makes it transparent for users when a different control interface
(e.g. GPIB, Ethernet, RS-232, and RS-485) is specified.
The internal operating system is specifically designed to universally
accept any CANbus components when expansion is required. There is
no need for any additional upgrades to the operating system. During the
initiation process (when powered up), the operating system identifies all
CANbus components and opens communication control channels.
Dow-Key Microwave offers full technical support for the system
integration process.

Steps in RMS system selection and information:
• Provide a block diagram and specifications describing the functional requirements
of the switching network
• Dow-Key selects required hardware and components and submits to customer for approval
• Customer chooses either Dow-Key providing the entire “turn-key” solution or procures
a RMS kit.
• In addition to end item hardware, the “turn-key” solution also includes product design,
design verification and manufacturing and test documentation.
• The RMS kit includes as a minimum; universal matrix cage, all CANbus controllable
devices and associated hardware and software. The flexibility of the RMS system allows
adding or removing CANbus components. The system can control over 100 components
connected to one control bus.
