MSC02

Modular System Control Board
The Modular System Control Board pictured above is the heart of the system.  It is a small 5.5” x 5.5” board designed to stack with other interface boards.   The board contains the main control processor, Ethernet, USB and RS232, RS422 & RS485 serial interfaces, and connectors for the optional modules, power regulator and 3 I2C connectors with 5V power for the I2C01 modules, I/O boards and the touchscreen display.

This board is powered from the system power supply (9 to 40 VDC) and can supply up to 1 A of 5V power to the display and I/O boards.

SW64D


SW64D Switch Driver Board  *** NEW PRODUCT ***
The SW64D board pictured above is a small  3” x 8.3” board which connects directly to the MSC02 controller via the I2C bus.  The board can directly drive 64 switch coils, relays or other high voltage high current low side loads.  The board contains the two I2C RJ-45 connectors, buffers and the microcontroller which handles the I2C interface protocol, command parsing and control for switches, attenuators and parallel I/O.  The micro-controller contains EEPROM non-volatile memory which is used to store configuration data and contact closure counts.  The module also has a voltage regulator to provide 3.3V logic power from the 5V power supplied by the bus cable.

GTT50P / GTT70P

5 Inch & 7 Inch Touchscreen Display
The GTT50P and GTT70P are a 5 and 7 inch full color touchscreen displays with an integrated piezo speaker for operator feedback. The display is controlled and powered by the MSC02 Controller Board via the I2C bus cable.  The GTT50P and GTT70P displays are shipped preloaded with all of the graphics files necessary to the standard MSC02 firmware and an I2C bus cable.  The OEM may purchase the display directly from the vendor and load the files in house if desired.  Please consult the factory for ordering options.

Custom I/O Boards


As the microcontroller is on the I2C01 module, interface boards can be simple 2-sided boards which significantly reduces the cost.  For a switch driver board, the I/O expanders and any necessary coil driver circuitry can be placed on the board near the switch connectors to reduce the length of the traces to the connectors simplifying the board layout.

The board can be designed as a backplane to plug directly onto a sub-assembly of switches.  As each switch manufacturer uses different connector types and pin connections which can vary with the model of the switch, it is likely that most switch controller boards will need to be custom layouts to fit the mechanical requirements of the OEM’s system.  As the design is scalable, circuit design and firmware will not need to be changed to support different numbers and types of switches.

SW72

72 Channel Switch Driver Board
An example 72-channel board is shown above, which supports nine H3-H6 series 3 to 6-position TTL input switches and nine  B series 2-position TTL input switches from Charter Engineering, Inc. all with indicator contact read-back (144 I/O lines).  The top board in the picture shows the component side of the board with the 9 I/O expander chips and the I2C01 module installed on the right.  The bottom board shows the connectors which plug directly onto the switch assembly eliminating all switch wiring.  The board has two power input connectors (up right corner of bottom board) to allow daisy chaining of the system power.  Coil voltage and board temperature are monitored and reported to the system controller.

SW40x13

40 Position Switch Driver Board
An example 40-position switch driver board is shown above, which supports 13 40-position TTL input solid state switches each switch has 30 control lines for a total of 390 I/O lines.  The top picture shows the connector side of the board with the switch connectors and the I2C01 module installed on the right.  The bottom picture shows the component side with the 16-bit I/O expander chips.  Voltage and board temperature are monitored and reported to the system controller.

KL01

6 Channel 4PDT Relay Board
An example relay board is shown above, which has 24 latching relays connected in 6 groups as 4 pole double throw with position sensing.  The relay positions are monitored for reliability.  Voltage and board temperature are monitored and reported to the system controller.  This board has been used in radio to antenna switch matrixes to control radio key-lines during antenna switching.  This board is double the size of the MSC02 Controller Board to allow stacking the boards in a chassis.

BKPS01

Interface I/O Board
An example interface I/O board is shown above, which has control inputs, LED drivers and a latching relay.  The relay position is monitored for reliability.  Voltage and board temperature are monitored and reported to the system controller.  This board has been used in radio to antenna switch matrixes to control radio blanking during transmissions.  This board is the same size as the MSC02 Controller Board to allow stacking boards in a chassis.

Prototype I/O Boards


Due to the fact that the I2C01 module connects to an I/O board with standard header pins on 0.1" centers, custom I/O boards can be easily constructed using standard off-the-shelf breadboards or perforated stock.  As the I2C interface and the microcontroller are on the module, the only parts that need to prototyped are the 16-bit I/O expanders and any additional drivers or circuitry needed for the application.  Standard ribbon cables can be used to connect additional boards such as evaluation boards in the examples below.


AD9910 Eval Board

The AD9910 Eval Board is an Analog Devices product with a AD9910 DDS chip on board.  A simple breadboard was constructed on perforated stock with one I/O expander and a power supply regulator module.  This board was used in a millimeter wave project to provide a sweep ramp.  The firmware on the I2C01 module was customized for this project.  The distributed processing architecture allows the module to do real time processing while the MSC02 controller board handled an Ethernet interface to a custom Window GUI program.

AD9959 Eval Board

The AD9959 Eval Board is an Analog Devices product with a AD9959 DDS chip on board.  A simple breadboard was constructed on perforated stock with one I/O expander and a power supply regulator module.  This board was used in a millimeter wave project to provide programmable VCOs.  The firmware on the I2C01 module was customized for this project.  The distributed processing architecture allows the module to do real time processing while the MSC02 controller board handled an Ethernet interface to a custom Window GUI program.
