1 Introduction
CrossPoint Technologies Model MS-500x Matrix Switches are available in a variety of input/output
configurations. The operation and remote control interfaces are identical for all devices. The MS-
5000 series are solid state switches The chassis size varies with the complement of switches
installed. Frequency range is customer specified.
1.1 Applicability
This manual covers a family of Matrix Switches. The following models are included in this manual:
MS-5000-32x8-LB-FO
MS-5000-16X16-VHF-UHF-077
MS-5000-16X32-VHF-UHF-S
MS-5000-4X8-VHF-UHF-S
MS-5000-32X4-LB-FO
Detailed specifications and additional information specific to each model are found in the
Appendix.
Other models are available for different frequency ranges or for different numbers of channels.
The MS-500x can be optimized to your application.
1.2 Terminology
Matrix switches are specified in one of two ways. If the matrix is designed as “full fan out”, each
input can be routed to all its outputs simultaneously. Each output has only one input at a time. If
the matrix is “full fan in”, each output can sum all inputs simultaneously. Each input can only be
assigned to a single output at a time.
These matrix configurations exhibit a “one to many” (fan out) or “many to one” (fan in)
characteristic. The internal configurations of these two architectures are often a mirror image of
one another.

2.2 Rear Panel
Rear panels are customized to the different matrix configurations. Specific drawings found in the
Appendix for each model that identify the connector reference numbers (“J numbers”).
3 Installation
The Matrix Switch mounts in a standard EIA rack. Some units use internal fans provide cooling
from side to side. Standard rack mounting will allow adequate clearance for the air vents on the
sides. The unit does not require empty rack space above or below.
3.1 Connections
3.1.1 AC Power
The Matrix is provided with a standard detachable US AC line cord. However, the internal power
supplies have universal voltage capability (220/110 VAC). Plug the equipment into an AC source
of either 110 or 220 VAC.
3.1.2 Serial Port
The serial port is a dual purpose connector located on the rear of the Matrix. The connector is
labeled CTRL. It provides RS-232 format signals as well as RS-422 signals. The chassis
connector is a common 9 pin male D connector.
3.1.2.1 RS-232 Operation
RS-232 is recommended for cable lengths up to 50 feet between the computer and the matrix.
Longer links can be accommodated reliably, but may require experimenting with slower baud
rates, lower loss cable and better shielding.
The link can operate at four baud rates between 2400 and 19200 bits per second. The baud rate
is selected by the front panel menus. The other communication parameters are fixed at 8 bit
words, no parity and 1 stop bit. Set your remote computer interface to the same settings. Factory
default is 19200 baud.
The serial interface does not support hardware or software flow control. Commands and
responses are relatively short and flow control is not normally required. The command/response
method assures that the host computer can sense if the Matrix is unable to accept more
characters.
The RS-232 interface is pin compatible with standard PC serial ports, which use RS-574 pin
assignments. To control the system from a PC, a “null Modem” cable is required. A Null Modem
adapter can be used with a “straight through” cable, or a custom cable can be wired, following the
diagram below.

3.2 RS-422 Remote Control Operation
RS-422 operation allows data communication over cables of up to 4,000 feet. Use RS-422 when
the remote computer must be located far from the matrix chassis, or when ambient electronic
noise levels are very high. The RS-422 standard uses balanced differential signaling, for
significantly more reliable communication than RS-232. The drivers and receivers are RS-485
compliant, which makes them suitable for direct interface to full duplex RS-485 systems as well.
The link can operate at four baud rates between 2400 and 19200 bits per second. The other
communication parameters are fixed at 8 bit words, no parity and 1 stop bit. Set your remote
computer interface to the same settings. For long runs, a termination might be required to assure
reliable communication at high baud rates. If you experience data integrity problems (parity errors,
garbled data) try slower baud rates. If slower baud rates help, then try the faster rates with a 120
ohm terminating resistor across the receive data pins (RXA and RXB). Terminate each pair at its
receiver. The terminations can be installed inside the back shells of the cable connectors. The
actual resistance value may be adjusted to match the cable’s characteristic impedance. A value of
120 ohms is typical for twisted shielded pairs.
The serial interface does not support hardware or software flow control. Commands and
responses are relatively short and flow control is not normally required. The command/response
method assures that the host computer can sense if the Matrix is unable to accept more
characters.

Rev D Model MS-500x
CrossPoint Technologies, Inc 5
The interface requires 2 twisted pairs of wires between the communicating devices. Shielding is
recommended over the two pairs. For best performance and safety, do not ground the shield at
both ends. Leave one end of the shield unconnected. If each pair is individually shielded, ground
the shield at its source end (driven end) and leave it floating at its receiving end.
The suggested drawing below is for the RS-422 interface using 2 twisted shielded pairs. The
computer side does not show pin numbers, as there are many forms of RS-422 connectors
available. Notice the individual shields are grounded at opposite ends, and there is no ground
continuity between the two devices (the two shields are assumed isolated from each other). In
long runs, this serves to protect both devices from carrying ground currents, especially in the
event of a power line fault in either device. If your cable has individual shields that are in intimate
contact with each other, it may not be possible to avoid ground current flow down the cable shield.

Figure 3 : Computer to Matrix RS-422 Wiring
A standard PC RS-232 port can be transformed to balanced operation using an “RS-232 to RS-
422” or “RS-232 to RS-485” adapter device. These devices are available from a variety of
sources. Some can be powered directly from the RS-232 handshake signals available at the PC
connector. This type is recommended, as it does not require a separate power supply or
transformer for operation.
Suggested sources for these adapters are B&B Electronics (www.bb-elec.com or 815-433-5100)
and Black Box Network Services (www.blackbox.com or 877-877-2269).

4 Front Panel Operation
After all connections have been made, power up the Matrix. The matrix will power on in Local
mode, so the front panel is enabled. After displaying the model number, and initializing itself, the
matrix will set itself to the connection paths that existed when it was powered down.
The following sections discuss general operations. Detailed operating sequences appear after the
general discussion
4.1 Remote and Local Modes
Manual operation is permitted whenever the matrix is in Local mode. The front panel can always
be used to view the state of the matrix. But to make changes, the matrix must be placed into
Local mode.
The remote computer can place the matrix in Remote mode, thereby disabling changes from the
front panel. However, the matrix can be returned to Local mode using its front panel menus. The
remote computer can also place the matrix into Local Lockout state. In Local Lockout state, the
front panel is disabled and cannot be used. The remote computer must release the matrix from
Local Lockout state before front panel control can occur. To allow recovery if the remote computer
fails, the matrix can be power cycled. It will always release the Local Lockout and revert to Local
state at power up. The matrix paths will be interrupted during this power cycle operation.
4.2 Setting Switches
To change the matrix connection in a fan in switch, first select the Input that is to be sent to a
different output, by pressing the IN key. To change the matrix connection in a fan out switch, first
select the Output that will have a new input assigned to it, by pressing the OUT key.
Pressing IN/OUT will change the LCD display to an edit mode. A blinking cursor will appear to
indicate the Matrix is waiting for data. Use the numeric keys to specify the desired port, or use the
UP and DOWN keys to increment/decrement through the available port numbers. When the
display shows the desired port, press ENTer to confirm the choice. Pressing ESC will cancel the
edit. At this point, no change has yet occurred to any connections.
Now press OUT for a fan in switch, or press IN for a fan out switch. The appropriate field will
change to edit mode, with the blinking cursor. The text message for this field includes the notation
SEL to indicate that this field is the one that actually makes RF changes. Changes made here are
going to affect the actual paths through the switches. Use the OFF key to break the RF
connection, or enter 0 as the selection. When the display shows the desired port, press ENTer to
confirm the choice. Pressing ESC will cancel the edit. The new RF connections are established at
this time.
As digits are entered, they scroll left, to the maximum number of digits allowed for the matrix. If an
incorrect digit is typed, follow it by correct digits, allowing the erroneous digit to “fall out” of the left
of the display area. Leading zeroes may be entered to flush erroneous digits. The ENT key
accepts only the digits actually displayed. An entry of “0” is the same as pressing the OFF key
When the ENT key is pressed, the Matrix verifies that the number entered by the operator is
within the valid range of the matrix. If the operator enters a number that is out of range for the
matrix (e.g. typing in “9” for a 8x8 matrix), the operation is aborted, and the LCD displays the
previous selection. No change occurs in the RF path. If the number is accepted, the change is
made to the RF path, and the display is updated. Any leading zeroes are removed and the cursor
disappears

4.3 Using the Menus
The menu system provides screens for configuring certain internal parameters, such as serial
interface baud rates. It also provides status information regarding internal fault monitoring. There
are screens to restore the matrix to its default settings. Menus are multi-level hierarchies. The
operator chooses a level and moves to the next lower level until the specific items are reached
The normal display is the Connection screen, showing the state of the RF matrix. Press the
MENU key to change to the first menu heading. Use the UP/DOWN keys to scroll through the
headings. Press ENT to move down into the multi-level menus. Press ESC to return to the next
higher menu level.
Once a specific parameter is reached, the parameter can be changed by using the UP/DN keys to
see the various options. When the desired value is displayed, press ENT to make that the current
value of the parameter. Press ESC to abort, and return to the next higher level.
Certain parameters require that the matrix be reset. The reset operation occurs automatically,
without powering off the matrix. The LCD will show “Resetting” followed by the normal initialization
screen. The RF connection will be restored, typically without actually being broken. The reset
operation occurs whenever a communication parameter is changed (RS-232, RS-422 or Ethernet)

The sequence of keystrokes to make a connection will differ for Fan In vs. Fan Out switches. Fan
Out switches allow each output to be connected to only a single input at a time, while allowing any
input to be connected to multiple outputs simultaneously. Conversely, a Fan In matrix allows an
input to be connected to a single output at a time, while an output can receive signals from many
inputs simultaneously. The LCD display cannot easily show the multiple connections. Therefore,
Fan Out switches are controlled by first specifying an output, and then selecting an input to route
to that output. Fan In switches operate by first selecting an input and then selecting its single
destination at an output.
The display above is from the 32x8-FO. The Output is noted as “SEL OUT” to reinforce the idea
that the Output is being changed when a new selection is entered.
Begin by pressing the OUT key. The channel number can be entered using the numeric keys or
by the UP/DN keys to scroll. Press ENT when complete. Pressing OFF will turn the RF path off
completely. Entering an Input value of 0 will also turn the output OFF. After ENT is pressed, the
blinking cursor will disappear, indicating that the connection has been made. If a number is
entered that is out of range, the screen will revert to the previous Input, and no change in
connection will occur. Pressing ESC will exit the Edit mode without making any changes.

The default condition is for static IP addressing. Therefore, DHCP is off by default. The DHCP
selection menu appears first because its state will have an effect on data items presented in later
menus.

Pressing ENT will enter the DHCP edit mode. Then use the UP/DN keys to set DHCP ON or OFF
as desired. Press ENT to accept the setting and return to this level of the menu. Press ESC to
abort any change and leave the current value in place
The next menu item is the IP address screen. This screen shows either the static IP address
assigned during setup (when DHCP is off) or it shows the address received from the DHCP
initialization process if DHCP is enabled. If DHCP is enabled, but no address has been assigned,
the screen will show an address of 000.000.000.000. In this case, communication with the matrix
is not possible.

If DHCP is off, press ENT to manually set the IP address. Your network administrator will be able
to help determine this address. The address must be manually typed using the numeric keys.
Leading zeroes must be entered, as each field is a fixed 3 characters. Press ENT when done to
accept the new address and return to the upper level menu. If DHCP is enabled, this screen is
read-only.
The next menu item is the IP Port value. The default is Port 23, the standard port for Telnet
services. If another port is desired, it may be set here. Ports in the full range 1..65535 are
accepted. Leading zeroes are not required for this item.

When using static addressing (DHCP Off), a network mask must be supplied. The next menu
item allows this mask value to be entered. Like the IP address, leading zeroes are required
because the number is broken into 4 fields, and a decimal point key is not available. Set the
netmask according to the addressing system used in your network. Your Network Administrator
will know what this value should be.

If DHCP is On, this field is read only, and shows the last value entered manually, not the value in
use on the network.
For system administration, it is often important to know the hardware MAC (Media Access
Control) address. This address is assigned in silicon at the factory, and is globally unique among
all Ethernet devices. The next menu item displays the MAC address of the matrix switch, and is
read-only.

In some networks the System Administrator will want to put a name for the switch into the IP
routing tables. If DHCP is being used, the IP address can change dynamically, so it becomes
difficult to find the matrix by its IP address. A name can be assigned, so that the matrix can be
found by name-server techniques. To simplify this setup, the switch matrix creates a unique name
for itself and registers this name with the local router during DHCP initialization. The name is
always of the format “CPTI_” followed by the last 6 characters of its MAC address. (The first 6
characters of the MAC will always be the same for all CrossPoint products, so they add no
uniqueness to the name). The CPTI_ header allows the matrix to be easily identified in a router
table by the System Administrator, and matched to a specific switch matrix.

4.4.6 Set Defaults
This menu item erases all communication parameters, and sets the matrix to RS232, 19200
baud. All switches are set to their OFF condition (Failsafe models revert to failsafe condition). The
Matrix resets itself and will be operational again in about 6 seconds.

5 Remote Control
5.1 Interfaces
The matrix system may be controlled by serial port or by Ethernet (if installed). For serial control, a
dumb terminal or terminal emulator program, such as HyperTerm (found on most PC’s) provides
a manual interface for simple command entry and status message readback. For Ethernet
control, a Telnet program (or Hyperterm) provides similar capability across the network.
The matrix system does not echo characters as they are typed, so use the Local Echo feature of
your program to see what you type. Every completed command returns either a copy of what was
received, or an error code. This reply returns after the command has executed, signaling that the
command was acted upon.
5.2 Protocol
All messages and responses over the User IO interface are ASCII strings. No binary data is
transmitted over this interface. Commands consist of 2 ASCII characters and may require an
optional parameter string. Commands are terminated by carriage return (hex 0D). Execution does
not begin until the carriage return is received.
Multiple commands may be sent on the same line if separated by a semicolon (“;”). Incoming
command strings are limited to 63 characters, including the carriage return. Outgoing responses
are truncated if they would exceed 255 characters.
In most cases, a command mnemonic can be followed by an ASCII question mark (“?”). This form
of the command will be interpreted as a status request and the current value associated with that
command will be returned. The state of the device will not be altered by a status request.
Parameters are typically separated by commas. Certain commands can have multiple parameter
sets which are separated by parentheses.
The 2 character mnemonics are case insensitive on receipt, but will be upper case in the
response.
Transmit and receive operations are synchronous to one another. Incoming commands and
status requests are executed in the order received. Responses are returned when the command
is complete. All commands are echoed after completion as a verification to the remote computer.
If the host computer does not wait for the response string, it should allow 250 msec between
commands to ensure that it does not overrun internal buffers.
When input numbers or output numbers are required as parameters, they may omit leading
zeroes. Up to 3 characters are accepted. The maximum matrix size is 999 x 999.
When parameters are out of range (e.g. an input number is higher than the number of installed
inputs), those specific portions of the command are ignored. In commands which include lists of
items, all items are processed unless an error is encountered. All items after an error are
discarded, as well as the error itself. An error response is returned.
