Page 7: General Information
General Information Introduction The Dow-Key Microwave 1U MS, MP, CB Switch Matrix series are electromechanical RF matrices. They come equipped with an Ethernet port which allows the user to easily access the matrix from anywhere in the world via TCP/IP on 100BaseT networks. Other interfaces included are an RS-232 port, an USB (used as virtual serial port) and a CAN Bus port. -

Part Numbering Examples: MS-1U18S-4/X-ENET Is a Multi Switch matrix with following characteristics: 1U, 18 GHz, SMA, 4 transfer switches, ENET MS-2U26S-4/6T-ENET Is a Multi Switch matrix with following characteristics:... -
Page 9: Mp Matrices
General Information 1.3 MP Matrices MP-Series stands for Multiplexer. It is a matrix with one input connecting to many outputs (only one at the time) or, since the RF switches are bi-directional, many inputs connected to one output (only one at the time). The switches are populated either on the rear panel or inside the matrix chassis. -
Page 10: Cb Matrices
General Information 1.4 CB Matrices CB-Series stands for Crossbar. It is a matrix with several inputs connecting to several outputs. Only one input can be connected to one output at any given time. The switches are populated inside the matrix chassis and are interconnected so that any input can connect to any output and vice versa. -

Page 21: Configuring The Matrix For Operation
Configuring the Matrix for Operation Matrix Configuration The ‘brain’ inside Dow-Key Matrices, referred to as the “Matrix Controller”, has been designed to be as general as possible in regards to how many switches of what positions it may control. Therefore, the matrix must first be informed as to the set of switches it is able to control before it can operate successfully, and this information must be updated as switches are added and deleted to the matrix or connected to the CAN bus port on the rear of the matrix (see section... - Page 22 Configuring the Matrix Adding and Deleting Switches The following rules apply when adding a switch to the Matrix Configuration (the desired ID to add is referred to as the “target ID”): The desired switch to ADD must be connected to the matrix before ‐...
-
Page 23: Configuring The Ethernet Connection
Configuring the Matrix Example procedure: Adding a switch to the Configuration usually starts by finding the ID of the physical switch to add. Select Main Menu>System Settings>Find Switch ID and follow the instructions in Section 5.2.3 Find Switch ID. TAKE NOTE OF THE INFORMATION REGARDING SWITCH FIRMWARE REVISION IN STEP If the switch’s ID is the one desired to add (0 or N), the switch may be left connected and the BACK key may be pressed to return to the Main Menu. -
Page 24: Connection To An Ethernet
Configuring the Matrix Connection to an Ethernet The use of a standard “Straight Through” Ethernet cable is required to connect the matrices to an Ethernet LAN hub. Connection to a single computer requires the use of “Crossover” Ethernet cable. -
Page 25: Testing Ethernet Communication
Configuring the Matrix Testing Ethernet Communication The matrix’s ability to communicate should be tested once it has been configured and connected to an Ethernet network. Connection thru a network: Assuming the matrix’s default IP address setting has not been changed from obtaining the IP address dynamically, take note of its IP address during the boot-up process (or se section 5.2.4 to read its IP address). - Page 26 The matrix’s Ethernet interface was designed to operate with common network utilities and drivers. If the Matrix fails to communicate, contact your network administrator for additional assistance. If your network administrator is unable to locate the problem, please contact Dow-Key Microwave Corporation at 1- 805-650-2327.

Manual (LOCAL) Operation The Keypad / LCD Interface Power On: Position the rocker switch on the rear panel of the Matrix to the on position (Figure 2-2) to turn on the matrix. ! Note: The booting sequence will last about 15 seconds in which the LCD will appear blank. - Page 28 Manual (LOCAL) Operation UP and DOWN serve as “scroll up”, “scroll down”, “increment”, or “decrement”. Many data fields’ values are modified by UP and DOWN, and many of those allow the pressing and holding of the UP and DOWN keys to cause an acceleration of the incrementing or decrementing.
