1 General Information
1.1
Introduction
The Dow-Key Microwave 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. Any model 2 RU or
higher also comes equipped with a touch screen LCD front panel display for
manual (Local) operation. 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.
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.

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).

CAN Bus Connection
This connection allows the matrix controller to be easily interfaced to another
Dow-Key Microwave Switch Matrix, using a one-to-one (straight through) cable.
However, the Matrix being interfaced must not have any internal, intelligent
controller; it must be a simple RF Switch Matrix. Furthermore, the switches in
the matrix being interfaced must have CAN ID’s unique to any others
connected to the matrix. See Section 4 for more information.
Care must also be taken to limit the current draw on the +12 VDC to a
maximum of 7 Amps.
Figure 3-3 and Table 3-3 show the pin numbers and functions for the CAN Bus
connector.

Connections
3.5
Ethernet Connection
The matrix comes equipped with an Ethernet port (RJ45 connector) which
allows the user to easily access the matrix from anywhere in the world via
TCP/IP on 100BaseT networks. See Section 4 and Section 6 for descriptions
regarding how to connect to, configure, and operate the matrix over this
100BaseT Ethernet connection.
3.6
USB Port
Connecting the matrix to a PC’s USB port should result in a “Found New
Hardware” event. Follow the instructions until prompted for the new hardware
device’s driver, which may be located on the CD shipped with the matrix.
After installation, the matrix’s USB port will appear as a virtual serial port.
Communicate to this port as you would on any RS 232 serial port. The baud
rate is 9600 b/s. See sections 3.3 and 6 for more details.

4 Configuring the Matrix for Operation
4.1
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
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.
In addition to switch information, the Matrix Configuration also contains other
information such as the base MAC address, unit’s Serial Number, alarm
enabling, Model Name, etc. This information must remain intact for the matrix
to operate properly.
The matrix configuration is already performed at the factory and does not need
to be done by the user unless the Matrix Controller board has been replaced.
Adding and removing switches (see sections 5.2.3 and 7.3) automatically
updates the matrix configuration. No further action is required by the user.
4.2
Configuring the Ethernet Connection
All devices connected to an Ethernet and communicating via TCP/IP must have
a unique IP address and TCP Port number.
The DowKey matrices are programmed at the time of its manufacture to have a
Dynamic IP address (Dynamic Host Configuration Protocol is ON). See sections
5.2.4 and 6.7 for more details on how to obtain an IP address dynamically or set
it manually as static.
When the IP address is obtained dynamically (DHCP is ON) the IP address is
displayed for a few seconds at power up. See section 5.2.4 to display the IP
address after boot up is completed.
The matrix is programmed at the time of its manufacture to have the following
default settings:
• IP Address:
obtained dynamically
• TCP Port Number: 10
See Sections 5.2.4 for instructions on how to set the IP Address and TCP Port
Numbers to other values.
4.3
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.
19
Configuring the Matrix
4.4
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). Assuming the
connection has been made with a personal computer connected to the same
network and running some version of Microsoft Windows©, select
Start>Run
and type
Ping nnn.nnn.nnn.nnn
where nnn.nnn.nnn.nnn is the matrix IP address previously noted.
Connection to a standalone PC:
If the matrix is connected directly to a standalone PC (rather than a network),
set the IP address of the matrix so that the first 3 numbers match the PC’s IP
address. The last number must be different.
Example:
PC IP address:
200.169.200.180
Matrix IP address: 200.169.200.181
Assuming the connection has been made with a personal computer running
some version of Microsoft Windows©, select
Start>Run
and type
Ping nnn.nnn.nnn.nnn
where nnn.nnn.nnn.nnn is the matrix IP address. In this example
200.169.200.181

5 Manual (LOCAL) Operation
5.1
The Touch Screen Interface
Power On:
Position the rocker switch on the rear panel of the Matrix to the on position (Figures 2-2,
2-3 and 2-4) to turn on the matrix.
! Note: The booting sequence will last up to 1 minute in which the LCD can at times
appear blank.
The matrix will power up in LOCAL Operating Mode. LOCAL Operating Mode means
that the matrix is receiving commands from the front panel (LCD/Touch Screen).
When in LOCAL Operation Mode the matrix will switch automatically in REMOTE mode
as soon as commands coming from a remote control computer are received (Ethernet,
Serial or USB). The only buttons that will respond while in REMOTE mode are:
-
From the ‘Main Menu’ the ‘Switch Operations’ button.
-
From the ‘Switching Menu’ the ‘Current Positions’ button.
Other than the above two buttons the matrix will not accept any other local commands
until the operator switches to LOCAL mode by pushing the ‘Go Local” button on the
LCD.
As stated before, to switch to REMOTE Operation Mode the operator needs to send a
command (Ethernet, Serial or USB) by means of a remote control computer or push on
the ‘Go Remote’ button on the LCD.
All LOCAL operation of the matrix is accomplished via the front panel’s Touch Screen
LCD. Regions that respond to touches are called Active Areas or Buttons.
IMPORTANT NOTE: The touch screen is best operated with a stylus, rather than a
fingertip. The LCD will respond better to a taping action rather than just touching it.
22
Manual (LOCAL) Operation
The figure above shows the matrix LCD touch screen (sometimes referred to as the
“User Interface”, or “UI”) at the main menu screen.
Most buttons have a gray background, while indicators will be either green or red. All
screens, with exception of the ‘Main Menu’ screen, will have a green ‘back’ button to
return to the previous screen.
In the above picture the matrix is indicating that there are No Errors (see green
indicator) and the matrix is in LOCAL mode (see green indicator).
If an error condition is detected the green ‘Error” indicator will illuminate red.
The LCD in the figure above shows the top level of the matrix’s operational screen,
which happens to be a menu; the gray buttons are used to select menu items. Other
screens encountered allow the operator to modify various parameters’ values; all such
“data fields” are presented with a currently set or default value blinking, prompting the
operator to modify the value. Some screens present multiple data fields, and a virtual
keypad with arrows will appear to navigate around them and change the values.
! Note:
To preserve the life of the LCD, it has a ‘screen saver’ feature. After 5 minutes the LCD
backlight will turn off. To turn it back on, tap anywhere.
The various screens encountered in the matrix’s operation contain the following
controls:

Set Switch Positions
View the currently set position and change the position of a
switch who’s ID has been configured to the matrix. Use the
arrows to change switch and position numbers.
Refer to Appendix B to set the RF switches in the correct
desired positions.
Current Positions
View the currently set positions of all switches whose ID’s have
been configured to the matrix. This screen can show a
maximum of 12 switches at a time; press NEXT button to view
the next set of a maximum of 12. Note: the presentation of
switch positions is a “one way” experience in that the operator
can only view successively greater ID’s. BACK will bring the
Operator back to the Switching Menu.
Remember that a switch position reported as 255 (0xFF) is
meant to mean “position unknown”, and is often the result of a
switch not responding to a query for position.
Note that all Dow-Key switches have “open” defined but not all
switch types have an actual open position (the switch is not
closed to any of its RF ports).
For most switches this “open” is the default position and is
defined as position 0. But for transfer switches there is no
“open” condition, hence the default position is pos.1. As a result
of this, commanding the switch to pos 0 or pos 1 will have the
same result, closing it to its default position 1.

Recall Positions
Recall from non-volatile memory the state of the positions of all
switch ID’s configured to the matrix, saved as 1 through 30, and
set the positions of those switches.
Clear Positions
Cause all switches configured to the matrix to assume their
default position. For most switches this is position 0 (open
positions). Note that all Dow-Key switches have “open” defined
but not all switch types have an actual open position, such as a
transfer switch. In this case “open” means “close on its default
position 1”.
Cycle Positions
Step all switches configured to the matrix through all of their
positions. NOTE: the Cycle Position function is intended for use
at the Dow-Key factory during the assembly process. In fact,
the Cycle Position function will generate errors when
commanding a Transfer switch to switch from position 0 to
position 1, which may be ignored. For this reason, the Operator
is discouraged from exercising Cycle Positions.

The Error Data contains various parameters associated with certain
Errors. For instance, an Error Code 10 “Switch Did Not Respond” will
show the offending switch ID in the Error Data field.
As each error is being read (displayed locally or queried remotely) it will
also be removed from the Error Log.

! Important Note:
The matrix controller is designed to offer the maximum expandability and
flexibility possible and therefore has features common to other Dow-Key matrix
models. The here described ‘Add’, ‘Delete’ and ‘Find Switch ID’ features are
some of those that, although available and fully functioning, should only be
used if needed and appropriate.
Switches may be added and deleted from the Matrix Configuration using these
commands.
For those matrix models with a custom or fixed RF configuration (in other words
where the internal RF switches and its connections are defined on a custom
bases or are established and fixed by design), no switch shall be added or
removed from the matrix configuration. Not following this instruction will result in
a non working matrix!

Find Switch ID
Discover and view the ID of any switch by following these steps:
1. Using a matrix with at least one unused CAN Bus connector,
and leaving the switch in question unconnected, select Main
Menu>System Settings>Find Switch ID. The screen will
indicate that no switch is connected.
2. Connect the switch in question. The screen will now display
the unknown switch ID. NOTE: occasionally, the switch will
not immediately report its ID; in this case, simply disconnect
and reconnect the switch.
3. Multiple switches may be connected and disconnected one
at a time while in this screen.

Manual (LOCAL) Operation
4. NOTE: this operation “puts the matrix’s switches to sleep”
thereby rendering the matrix inoperable during the process.
ENTER or CLEAR or rebooting returns the matrix to normal.
5. NOTE: proper performance of Find Switch ID relies on the
behavior of Dow-Key Switch firmware revision 4 and above –
revision 3 and below does not allow “putting the switch to
sleep”. So, this feature is best executed on a matrix that
does not contain switches with firmware revision 3 or less, or
those switches will respond with their ID’s as well as the
switch in question. The revision of firmware of any switch
configured to the matrix may be learned with Main
Menu>System Settings>Switch Information (see below).
Temperatures
View current values of a maximum of 4 temperature sensors,
and set thresholds at which an Over Temperature alarm should
occur. Setting all 4 alarm thresholds to 0° Celsius disables Over
Temperature alarms and causes the current temperatures to

Products that contain no temperature sensors.
Most standard Models do not feature temperature
sensors.

Introduction to SCPI
SCPI is a command structure that is based on the IEEE-488.2 specification
which Dow-key has adapted to work with Ethernet, RS-232 and USB controls.
The matrix has internal software loaded that uses SCPI command structure.
SCPI is the abbreviation of Standard Commands for Programmable
Instruments. These commands are standard messages for the (remote) control
of programmable instruments, which are sent by the Ethernet and/or RS-232
and/or USB controller. The principal objective of SCPI is to make the
programming of a test system easier for the user. When the basic concepts
and command structure of SCPI is understood, it will be easy for the user to
write or modify a control program for the matrix.
The Socket Type of the matrix is server while your remote control computer is
the client.
NOTE: Not all commands for SCPI are compatible with Ethernet, RS-232
and USB, only the ones stated in this document.
6.2
Command Syntax Structure
[ROUTe]:SWITch<id>[:VALue] <number>|MAX
•
•
•
•
Square brackets [ ] indicate optional keywords or parameters.
Braces { } enclosure parameter choices with a command string
Triangle brackets < > enclose parameters for which you must substitute a
value.
Vertical bar | separates multiple parameter choices.
The command syntax shows most commands as a mixture of upper and lower
case letters. The upper case letters indicate the abbreviated spelling for the
command. For shorter program lines, the abbreviated form is used. For better
program readability, the long form is used. For example, in the above syntax
statement, ROUT and ROUTE are both acceptable forms. Since both upper
and/or lower case letters are acceptable, ROUTE, rout and Rout are all
acceptable. Other forms, such as RO and ROU are not acceptable and will
generate an error.
NOTE: Each command must be terminated with a carriage return (0×0D)
followed by a line feed (0×0A).
e.g. ”ROUT:SWITx n\r\n”
“ ROUT:SWITx n; SWITx?\r\n”
Where “\r” stands for carriage return (0×0D) and “\n” stands for line feed
(0×0A).
31
Remote Operation
6.3 Command Separators and conventions
•
•
•
•
•
A colon (:) is used to separate a command keyword from a lower level
keyword.
A blank space is used to separate a parameter from a command keyword.
A comma (,) is used if a command requires more than one parameter.
A semicolon (;) is used to combine multiple commands into one message
string. Commands from the same subsystem are permitted to skip repeating
the upper-level keyword.
Eg. “Route:Switch1 8; Switch2 5; Switch3 2”
A colon is used when linking commands from different subsystems into one
message string, allowing a new upper-level keyword to be introduced. Since
the keyword is optional, such keyword could also be omitted (see example
2).
Only the first command requires the colon. Any subsequent commands of
the same subsystem do not require the colon (see example 3).
Ex. 1: “Route:Switch1 8; Switch2 5; Switch3 2; System:Error?”
Ex. 2: “Route:Switch1 8; Switch2 5; Switch3 2; :Error?”
Ex. 3: “Route:Switch1 8; Switch2 5; Switch3 2; :Error?; Timeout 2; status?”
•
•
•
•
When linking multiple commands the maximum number of characters
supported is 220. The limit of 220 characters is valid in transmission and
receiving.
All messages are in ASCII format (numeric values are represented in
decimal format with exception of the MAC address which is expressed in
hex format).
Timing, sequences and action requirements are only shown where
applicable and are under the TIMING sub-paragraphs on each command
description.
Any string returned by the matrix is terminated with a carriage return (0×0D)
followed by a line feed (0×0A).
e.g. ”ROUT:SWIT2?\r\n”
will return
“1\r\n”
Where “\r” stands for carriage return (0×0D) and “\n” stands for line
feed (0×0A).

Common Commands
The following contains the common commands of SCPI that the Ethernet
controller is compatible with.
The possible error codes assume that the correct syntax is used and, in case of
a multiple command string the string is not too long.
If these conditions are not met, any given command can generate these error
codes: 3, 4, 30
6.4.1*IDN?
Syntax
*IDN?
Result
A string is returned which consists of the following parts:
Model
Model
Matrix model number
Possible error codes
None
Example
“*IDN?”
Result
“MS-2U18S-1/6T-ENET”
33
Remote Operation
6.4.2*OPC?
Syntax
*OPC?
Description
This query returns an ASCII character “1” when all pending operations have
been finished.
Result
ASCII character “1”.
Possible error codes
None
Example 1
*OPC?
Result
“1”
Example 2
:SWIT1 4; SWIT2 4; *OPC?
Result
“0”
Timing
In example 2 the matrix did not have the time to execute the command. Hence
a “0” is returned. A subsequent *OPC? will return a “1” as shown in example 1.
The timing to execute a command depends on the length of the command (in
case of concatenated commands).
As a rule of thumb electromechanical switches require approximately 30ms to
switch position. It is safe to consider some safety margin and increase this
timing to 40-50 ms when developing the control software.
34
Remote Operation
6.4.3 *RST
Syntax
*RST
Description
This command performs a device reset.
This will set the instrument so that all switches are in the default state.
For SPnT switches the default state is: all RF ports are open.
For a transfer switch the default state is: position 1 is closed.
Possible error codes
11, 12, 13
Timing
As a rule of thumb electromechanical switches require approximately 30ms to
switch position. It is safe to consider some safety margin and increase this
timing to 40-50 ms before issuing any other command after a *RST.
6.5
System Commands
The following contains the system commands of SCPI that the Ethernet and
RS-232 control is compatible with.
6.5.1 SYST:ERR?
Syntax
SYSTem:ERRor?
Description
Query the instrument’s error queue. A record of up to N errors is stored in the
instrument’s error queue. Errors are retrieved in first-in first-out (FIFO) order.
The first error returned is the first error that was stored. Each additional error
up to N is read by N subsequent queries (one for each error). For this
instrument N=10. The error queue has to be read until no more errors are
returned, otherwise the error status is not cleared.
Note: some of the listed error codes are here for backwards compatibility with
legacy products and other are reserved for future applications. Not all error
codes are applicable to this matrix.
Result
String with the following syntax:
code, message
code: Numeric value with the error code (0 if no error).
Message: String with error message.

Switch [Module] Command Set
The following contains the switch [module] commands of SCPI that the Ethernet
control is compatible with.
6.6.1 :SWITch<id>[:VALue] <number>
Syntax
[ROUTe]:SWITch<id>[:VALue] <number>
Description
This command is used to control the position of the switches. The switch
specified by the numeric suffix <id> is set to position <number>. Switch
positions are specified in a 0 to N fashion, therefore legal values for <number>
are from 0 to the maximum number of position for the switch. For example, a
SP10T switch has 11 positions, 0 thru 10. Position 0 means the switch is set to
its default position.
For most switches the default position is pos 0 (open switch). So in case of a
SP10T switch this means no position is closed.
In case of a transfer switch, since it does not have an open position, the default
position is pos 1. So commanding it to pos 0 will close it to position 1.
48
Remote Operation
6.6.2 Setting switch x to position n
x = switch [module] address.
n = position to set and must be within the switches parameter.
(Example: SP10T valid positions are 0 thru 10 only).
Examples:
• ROUTE:SWITCHx n
• ROUT:SWITCHx n
• ROUTE:SWITx n
• ROUT:SWITx n
• :SWITCHx n
• :SWITx n
• ROUTE:SWITCHx:VALUE n
• ROUTE:SWITCHx:VAL n
• :SWITx:VAL n
Possible error codes

Power on behavior

*RST effect
SP6T switch: will open all positions
Transfer switch: will close position 1
Timing
The timing to execute a command depends on the length of the command (in
case of concatenated commands).
As a rule of thumb electromechanical switches require approximately 30ms to
switch position. It is safe to consider some safety margin and increase this
timing to 40-50 ms when developing the control software.
Multiple switch commands are not executed in a sequential manner but rather
in parallel.

Remote Operation
6.6.3 Requesting Switch x current position
x = switch address.
Examples:
• ROUTE:SWITCHx?
• ROUT:SWITx?
• :SWITx?
Result:
Returns the current position of switch x.
Possible error codes
10, 11, 12, 13
Timing
The timing to execute a command depends on the length of the command (in
case of concatenated commands).
As a rule of thumb electromechanical switches require approximately 30ms to
switch position. It is safe to consider some safety margin and increase this
timing to 40-50 ms before issuing this command after setting a new switch
position.
Multiple switch commands are not executed in a sequential manner but rather
in parallel.

Action
Returns string in ’Model Name’ in the configuration file.
As a minimum will have model name.
Could also have: Vendor, model, serial number, firmware revision (The response shown in this table
is just an example).
Gives 1 if previous operation was completed and gives 0 if previous operation is still not complete.
Puts all switches in the default position. (Transfer switches in pos.1. Most other switches in pos. 0 =
open).
Closes position y on switch x (N.B.: on SP12T x is 1)
Gives current position of switch x (N.B.: on SP12T x is 1)
Turns DHCP mode ON or OFF
Returns DHCP mode
Returns system IP address
Sets system IP address to xx.yy.zz.aa
Returns TCP port number
Sets TCP port number to x
Returns system gateway address
Sets system gateway address to xx.yy.zz.aa
Returns system subnet mask address
Sets system subnet mask address to xx.yy.zz.aa
Returns system MAC address
Returns system serial number
Returns Time out setting for TCP/IP connection (n is in seconds)
Sets Time out setting for TCP/IP connection (x is in seconds)
Returns system error number and error description. (The response shown in this table is just an

Web Page Server Control
The matrix may be controlled by way of web pages served by the matrix over its
Ethernet port. With the matrix properly connected to an Ethernet (see Section 4), type
the matrix’s current IP address into a browser’s Address Bar. The following page
should appear:
The Operator may select ‘Matrix Control’, ‘Matrix Configuration’, or ‘Matrix Status’;
‘Factory Configuration’ is reserved for the sole use by Dow-Key Microwave.

7.2
Matrix Control
Clicking on ‘Matrix control’ will show the below page.
Remote mode commands may be typed into the Command text box and then clicking
on the ‘Send’ button. See section 6 for the remote command list and its syntax.
If the command implies that the matrix responds (for instance when querying the matrix)
the matrix’s response will be shown next to the ‘Answer:’ label.
The bottom half displays the current position of all switches currently configured to the
matrix. Their positions may be set by selecting one from a switch’s drop down box and
then clicking ‘Set’. Clicking on the ‘Get’ button returns the position of all switches.
56
Web Page Server
7.3
Matrix Configuration
Clicking on ‘Matrix configuration’ will show the below page.
! Important Note:
The matrix controller is designed to offer the maximum expandability and flexibility
possible and therefore has features common to other Dow-Key matrix models. The here
described ‘Add a Switch’ and ‘Remove a Switch’ features are some of those that,
although available and fully functioning, should only be used if needed and appropriate.
Switches may be added and deleted from the Matrix Configuration using these
commands.
For those matrix models with a custom or fixed RF configuration (in other words where
the internal RF switches and its connections are defined on a custom bases or are
established and fixed by design), no switch shall be added or removed from the matrix
configuration. Not following this instruction will result in a non working matrix!
This page also allows to set the temperature alarm threshold of the temperature
sensors. This feature is disabled by setting all 4 temperature alarm thresholds to 0°C.
Most matrices do not contain any devices that produce significant heat, therefore these
models do not feature any temperature sensors. Leave all 4 temperature alarm
thresholds to 0°C.
57
Web Page Server
7.4
Matrix Status
Clicking on ‘Matrix status’ will show the below page.
This page displays the current status of alarm sources (power supplies, fans,
temperatures).
If the matrix does not have a redundant power supply, fans with stall sensors and
temperature sensors, than this page will not display any of this information.
