These models do not have an internal controller with remote interface (ENET, GPIB, RS232 or USB) nor a local LCD/Keypad. They come equipped with a CAN bus port which allows the connection to the master matrix allowing the control of the switches in the extension module. These models are not intended to be used to power or control anything other than Dow-Key supplied switches. Connection of other CAN Bus products or other devices not described herein will void quality certifications and the warranty. Depending on the total amount of switches in your system (master and extension matrices combined), the extension matrix might or might not have internal power supplies or might be powered up by the master matrix. See section 3 for more details on this topic. This user manual covers all three matrix series since most features are the same among the various models. The user shall focus on the matrix series of interest and skip any section that does not pertain to his matrix. Information specific to your model (like technical specifications and RF configuration) can be found in appendices at the end of this manual. 2 General Information 1.2 MS Matrices MS-Series stands for Multiple Switches. It is a matrix where a number of independent switches are populated on the rear panel or inside the matrix enclosure. From an RF point of view the switches are not interconnected and all switch’s RF ports are available to the user on the rear panel of the matrix. Depending on the size of the switch and the quantities needed, the matrix size can grow from 1RU to 4RU (or even larger).

Part Numbering Examples: MS-2U18S-4/X-EXT Is a Multi Switch matrix with following characteristics: 2U, 18 GHz, SMA, 4 transfer switches, Extension MS-2U26S-4/6T-EXT Is a Multi Switch matrix with following characteristics: 2U, 26 GHz, SMA, 4 Terminated SP6T, Extension MS-4U18N-12/10-EXT Is a Multi Switch matrix with following characteristics: 4U, 18 GHz, N connectors,12 SP10T, Extension The part numbering is interpreted as follows: MS-[chassis size][frequency][connector]-[number of switches]/[type of switch]-[remote control type] [chassis size]: [frequency]: [connector]: [number of switches]: [type of switch] : 1U | 2U | 3U | 4U etc. 12 (for 12.4 GHz) | 18 (for 18 GHz | 26 (for 26.5 GHz) | 40 (for 40 GHz) B (for BNC) | N (for N) | S (for SMA) | K (for 2.9 mm) 1 | 2 | 3 | 4 | 5 |… |16 (or more if chassis size allows) 2T (terminating one port DPDT Æterminated SPDT) | X (for DPDT) | 4 (for SP4T) | 6 (for SP6T) | 8 (for SP8T) | 10 (for SP10T) |12 (for SP12T). If switch type is terminated, add ‘T’ to the number. Example: 6T (terminated SP6T) [number of switches]/[type of switch]: If different switch types are combined, repeat this section as needed. Example: MS-1U18S-2/X-2/6T-ENET [remote control type]: ENET (for Ethernet, RS-232, USB) | GPIB ( for IEEE-488, USB) | EXT (for Extension model with CAN bus port only). 3 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. From an RF point of view the switches are interconnected and all input/output RF ports are available to the user on the rear panel of the matrix. Depending on the size of the switch and the quantities needed, the matrix size can grow from 1RU to 4RU (or even larger).

Part Numbering Examples: MP-4U18S-100-GPIB Is a Multi Plex matrix with following characteristics: 4U, 18 GHz, SMA, 100 outputs, GPIB MP-4U18S-20-EXT Is a Multi Plex matrix with following characteristics: 4U, 18 GHz, SMA, 20 outputs, Extension MP-[chassis size][frequency][connector]-[number of ports]-[remote control type] [chassis size]: [frequency]: [connector]: [number of ports]: 1U | 2U | 3U | 4U etc. 12 (for 12.4 GHz) | 18 (for 18 GHz) | 26 (for 26.5 GHz) | 40 (for 40 GHz) B (for BNC) | N (for N-type) | S (for SMA) | K (for 2.9 mm) 20 | 30 | 40 | 50 | 60 | 70 | 80 | 90 | 100 (and more ports if chassis size allows) If ports are internally terminated, add ‘T’ to the number. Example: 20T, .. , 100T [remote control type]: ENET (for Ethernet, RS-232, USB) | GPIB (for IEEE-488, USB) | EXT (for Extension model with CAN bus port only). Note: There is always one only input and a certain number of outputs. So no need to indicate the ‘1’ (for the input). 4 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. All input/output RF ports are available to the user on the rear panel of the matrix. Depending on the size of the switch and the quantities needed, the matrix size can grow from 2RU to 4RU (or even larger).

The same CAN bus connector might or might not carry the DC power for the extension matrix. Care must be taken to limit the total internal power supply’s current draw on the master matrix’s +12 VDC line to a maximum of 7 Amps. Note that this includes all switches of the master matrix and the extension matrix combined. If the total current draw is below 7A, the extension matrix will be powered by the master matrix (thru pins 1 and 4 of the CAN bus connector). Hence the extension matrix will have no internal AC power supplies. In cases where the total internal current on the 12Vdc line exceeds 7A, the extension matrix needs to have its own internal power supply, hence AC power inlet connector. 3.1.1 Line Voltage For models with internal AC power supplies, the matrix operates from a line voltage in the range of 110V to 240V at a frequency of 50 or 60Hz. Line voltage selection is automatic. CAUTION: Operating the unit on an incorrect line voltage may cause damage, possibly voiding the warranty. 3.1.2 Line Power Connection Perform the following steps to connect the matrix to line power: 1. Connect the female end of the supplied power cord to a grounded AC receptacle on the rear panel. 2. Connect the other end of the supplied power cord to a grounded AC outlet. WARNING: The power cord supplied with the matrix contains a separate ground for use with grounded outlets. Failure to use a grounded outlet may result in personal injury or death due to electric shock. 21 Connections 3.1.3 Line Fuse Replacement A rear panel fuse protects the power line input of the matrix. If the line fuse needs replacement, perform the steps below: WARNING: Disconnect the line cord from the unit before changing the line fuse. 1. The fuse is located in a holder in the power module unit above the AC receptacle (figure 3-1). At top is a small tab, use a small bladed screwdriver to release the fuse holder. 2. Slide the fuse holder out to gain access to the fuse carrier and fuse. 3. Remove the carrier with the blown fuse, and replace with the correct type listed in Table 3-1. CAUTION: For continued protection against fire or unit damage, replace the fuse only with the type and rating listed. 4. Install the fuse carrier in the fuse holder, then insert the fuse holder back in the power entry module. Insert small bladed screwdriver to release the fuse.

If the fuse needs replacement, perform the steps below: WARNING: Disconnect the CAN bus/power cable (Part Number 41099-073-xx) from the unit before changing the fuse. 1. The fuse is located in a holder on the rear panel. To release the fuse unscrew the fuse holder. 2. Remove the blown fuse, and replace with the correct type listed in Table 3-2. Note: On some bigger matrices, depending on the amount of switches and switch types, the current demand might be higher, requiring a higher current rating of the fuse. Always replace the fuse with the same current rating as the original one you removed. 3. Screw the fuse holder back on.

However, the extension matrix must not have any internal, intelligent controller; it must be a simple RF Switch Matrix extension. Furthermore, the switches in the extension matrix must have CAN ID’s unique to any others connected to the master matrix’s controller. See Section 4 for more information. Care must also be taken to limit the internal power supply’s current draw on master matrix’s +12 VDC line to a maximum of 7 Amps. Note that this includes all switches of the master matrix and the extension matrix combined. If the total current draw is below 7A, the extension matrix will be powered by the master matrix (thru pins 1 and 4). In cases where the total current exceeds 7A, the extension matrix needs to have its own internal power supply. In these cases the interconnection cable shall only use pins 2 and 3 for the CAN bus communication. 24 Connections Figure 3-3 and Table 3-3 show the pin numbers and functions for the CAN Bus connector. 3 2 1 4 Figure 3-3, CAN Bus Connector Pin Numbers The mating connector is Deltron 700-0400.

CAN HI 4. 12 VDC Return (GND) Table 3-3, CAN Bus Connector Pin Functions 25 4 Configuring the Matrix for Operation 4.1 Matrix Configuration The ‘brain’ inside Dow-Key Master Matrices, referred to as the “Matrix Controller”, has been designed to be as generic as possible in regards to how many switches of what positions it may control. Therefore, the Master 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 Master Matrix or connected to the CAN bus port on the rear of the Master Matrix (see section 3.4). The knowledge of what switches are to be controlled and how many positions each of those switches has is known as the matrix’s Configuration Data. This information must remain intact for the matrix to operate properly. Connecting your Extension Matrix to the Master Matrix requires the configuration to be updated as this is equivalent to adding switches to the Master Matrix. Adding and removing switches (see sections 4.3) automatically updates the matrix configuration. No further action is required by the user. The topics discussed in sections 4.2 and 4.3 are not needed during normal operation of your matrix. These sections are here for informational purpose and in the event the RF configuration of the matrix is being modified by adding/removing switches or connecting an Extension Matrix. 4.2 Dow-Key CAN bus switches A CAN Bus switch may assume a maximum CAN ID of 127. To facilitate the distinction of switches in the Extension Matrix, these have been addressed starting with a CAN ID of 101. For instance, assuming your Extension Matrix has 4 switches, their CAN IDs will be 101, 102, 103 and 104. A CAN Bus switch may have a maximum of 255 positions (0 through 254). 255 is reserved as a return value indicating that the switch is either in an erroneous position, or is reported to the Operator to when a switch fails to respond to a query for current position. 26 Configuring the Matrix 4.3 Adding and Deleting Extension Matrices The following rules apply when adding an Extension Matrix to the Master Matrix’s Configuration: ‐ The Extension Matrix to ADD must be connected (see section 3.4) to the Master Matrix before executing the ADD procedure. ‐ If the connected switches in the Extension Matrix have unique CAN IDs that are different from the IDs in the Master Matrix (see section 4.2) AND these IDs are not yet configured IDs, then these switches will be added to the Master Matrix’s configuration, i.e. the Configuration will be updated. The following rules apply when deleting an Extension Matrix from the Master Matrix’s Configuration: ‐ Physically disconnect the Extension Matrix from the Master Matrix (see section 3.4). ‐ If the switches to delete are not connected and are already Configured IDs, then the IDs will be removed from the Configuration Data. NOTE: THE MATRIX MUST BE POWER CYCLED AFTER MAKING ANY CHANGES TO THE CONFIGURATION BEFORE THOSE CHANGES BECOME FULLY APPARENT. 27 Configuring the Matrix Example procedure to add the Extension Matrix to the configuration data: Connect the Extension Matrix to the Master Matrix (see section 3.4). On the Master Matrix’s touch screen LCD go to the Main Menu (refer to the Master Matrix user manual for details). Select Main Menu>System Settings>Add Switch. The LCD will indicate “Switch ID0 NOT Detected”. Ignore this information. The LCD will also prompt to add the next available-toconfigure ID, the user must enter the connected Extension Matrix switch’s ID (for instance ID 101) then press the ENTER button. Repeat the above process for all switch IDs in your Extension Matrix. For instance if your Extension Matrix has 4 switches repeat the process 4 times and enter IDs 101, 102, 103 and 104). Example procedure to delete the Extension Matrix from the configuration data: Physically Disconnect the Extension Matrix from the Master Matrix (see section 3.4). On the Master Matrix’s touch screen LCD go to the Main Menu. Select Main Menu>System Settings>Delete Switch. The LCD will prompt to delete the highest available-to-delete ID, and the user must enter the connected Extension Matrix switch’s ID (for instance ID 101) to be deleted. Repeat the above process for all switch IDs in your Extension Matrix. For instance if your Extension Matrix has 4 switches repeat the process 4 times and enter IDs 104, 103, 102 and 101). Note: If sometime in the future you decide to not use the Extension Matrix anymore and want to revert the Master Matrix configuration to its original settings, you can delete the Extension Matrix IDs from the configuration data. When deleting the Extension Matrix IDs from the Master Matrix configuration data make sure to physically disconnect the Extension Matrix. Leaving the two matrices connected will result in the Extension Matrix switch IDs to be overwritten and set to a ‘virgin’ value of 0 (zero). Although this is not destructive, it would require to readdress the Extension Matrix switch IDs to the correct values (101, 102, 103, 104, etc.). Depending on the switch type this can only be done at the factory by means of an RMA. 28 Configuring the Matrix Note: Adding and deleting switch IDs to the configuration data can also be done by means of the embedded internal Master Matrix’s web page on the “Matrix Configuration” page. See the Master Matrix user manual for more details on how to control the matrix thru its web page. 29 Appendix A Technical Specifications Model: MS-2U40K-2/6-EXT Configuration: Two normally open SP6T switches mounted on the rear panel as independent switches RF Connectors: K-type (2.9mm) female (on rear panel) Frequency range: DC to 40 GHz Return loss (VSWR) Insertion loss Isolation RF Power: Frequency (GHz): DC ‐ 6 6 ‐ 12 12 ‐ 18 18 ‐ 26.5 26.5 ‐ 40 VSWR (Ratio max): 1.30 : 1 1.40 : 1 1.50 : 1 1.70 : 1 1.95 : 1 Insertion Loss (dB max): 0.3 0.4 0.5 0.7 0.95 Isolation (dB min): 70 60 60 55 50 RF Power (Watts CW max): 40 30 25 15 8 Note: RF power test conditions: Sea Level, +25°C, Load VSWR 1:1 Impedance: 50 Ω Switching Speed: 50ms (per switch) Operating Temp: 0 to 65 °C Switch Type: Two normally open SP6T.
