INSTALLATION

This NTI switch was designed to be mounted to a rack or to set on a desktop. It includes rack mount ears to make attachment to a rack easy, and rubber feet to be applied to the bottom of the case if it will instead sit on a flat surface. If this will sit on a flat surface, simply apply the rubber feet to the bottom of the case in each of the 4 corners.

To Mount to a Rack

1. (For SM-8X8-DVI-LCD, otherwise skip to step 2) Attach the ears to the switch using the #6-32x3/16" flat Phillips-head screws (6) provided as shown in the illustration below. The holes in the ears should line up with pre-threaded holes in the sides of the NTI switch. Tighten the screws securely.

OPERATING THE VEEMUX

The VEEMUX video matrix switch has four methods of control:

• Front Panel LCD with Keypad

• Directly via an RS232 Interface

• Remotely via Ethernet

• Infrared Remote (optional).

Every unit comes standard with all control methods built-in. An IRT-UNV-IR Remote Control is required (purchased separately) to use the Infrared option. No software is involved (see Infrared Control on page 36). With the RS232 option, there are no external devices to be purchased. NTI provides software commands as well as a test program to ensure the RS232 functions properly (see page 11 – RS232 Control).

Front Panel LCD with Keypad Control

The front panel LCD and keypad allow the user to monitor switch status and route any user to any video source on the switch.

When the unit is first powered-up, each monitor is automatically connected to the video source of its equal number (i.e. monitor 1 to source 1, monitor 2 to source 2, monitor 3 to source 3, etc.). (After configurations have been saved (page 23), upon power-up the VEEMUX will load the configuration saved into memory location 0.) Along with the routing of the inputs (video sources) to the outputs (monitors) the keypad and LCD allow the users to configure the RS232 control interface. The keypad buttons perform the following functions:

To change a connection

, simply press an Out number followed by an In number corresponding to the display device you want to connect to the video source. Whether the Out-x button or the In-x button is pressed first doesn’t make a difference.

To configure the VEEMUX, use the Menu keys.

Press the List button to list your main menu options:

1- Serial

2- Ethernet

3- DDC

4- Standby

Use the Up and Down Arrow keys to scroll through this list.

Use the Enter Key to select a menu item.

Press the List button again to exit the menu. If, while in a menu, you pause for more than 5 seconds, you will automatically exit the menu.

1. Under the “Serial” menu are two parameters:

1- Baud rate

2- Address

These parameters are used when the VEEMUX is controlled through an RS232 connection (page 11). If you select Baud rate, use the arrow keys to toggle through the available baud rates. The baud rate can be set to 115200, 57600, 38400, 19200, 9600,

4800, 2400, or 1200.

If you select Address, use the arrow keys to toggle through the address options (01-15). This is also the switch address used in conjunction with the IR Remote operation (page 40).

2. Under “Ethernet” menu are several parameters:

1- Mode

2- IP

3- Mask

4- Gateway

5- Primary DNS

6- Alt. DNS

The Mode parameter will let you select between a manual IP setting and a DHCP assigned dynamic IP address setting. An asterisk indicates which mode is configured, an arrow shows which mode is being selected. To change the configured setting and move the asterisk, select the desired mode and press the Enter button.

If you choose a manual IP setting, the IP parameter provides the fields for entering a valid IP address. Use the up and down arrows to advance the numbers, and the Enter button to move from field to field. Press List to exit this screen.

Selections 3, 4 are necessary to apply valid values for your Subnet Mask and Gateway. Navigate these settings as described for setting the IP address.

Selections 5 and 6 are not used at this time and are therefore unnecessary.

3. Under the “DDC” menu are two parameters:

1- Chose Input (Choose Input)

2- All Inputs

You can either 1) select the EDID information source for each input individually, or 2) for all inputs at once. Within this section you will need to select between:

direct- (available in 8x8 model only) the video source on an input will get EDID information from the video display device that is first connected to the output, regardless of what other display devices are also connected to the video source

default 1- the inputs will get EDID information from a predefined table in the VEEMUX supporting CPU monitors

default 2- the inputs will get EDID information from a predefined table in the VEEMUX supporting televisions

From Out (?)- select which Output port the Input will get EDID information from regardless of which output it is

connected to

More on “Direct” DDC: If the first output is switched to another input, the video source will look to the other connected outputs to get EDID information from, searching from the lowest numbered output port first.

For example: The video source on input 1 is connected to output 8, then 4, then 2, and then 5 for a total of 4 display connections. The video source gets it EDID from output 8, the first connected output. If output 8 is switched to another video source, the video source on input 1 will then get EDID information from output 2.

9


4. The fourth option in the main menu is ”Standby”. If you select Standby, the VEEMUX switch will immediately go into a power saver mode and the LCD display will go blank. It will remain in this state until

1) any button is pressed on the front panel,

2) the Standby button is pressed on the optional IR Remote Control (page 37), or

3) the “Disable Standby” button is pressed in the web interface (page 33)

Models SM-16X16-DVI-LCD and SM-32X32-DVI-LCD

The keypad control for the 16X16 and 32X32 models is very similar to that of the 8X8, with these differences:

•

The “In” and “Out” ports are selected by pressing the associated port number and then the “In” or “Out” button to designate the video source or the display (respectively). Alternatively, the “In” or “Out” button can be pressed, then the port number, followed by the “Enter” button.

•

Multiple displays can be connected to a single video source using one command sequence:

<In> xx<Out>xx<Out>xx<Out>xx<Out>xx<Enter> or

<Out>xx<Out>xx<Out>xx<Out>xx <In> xx <Enter> (where xx is the port number)

•

Within the “DDC” menu, “Default 1”, “default 2”, and “From Out (?) will work as described on the pevious page, however the “direct” option is not applicable.

•

The main menu has two additional options, 5-Save Config and 6-Load Config, described below

•

The list of current connections shown on the LCD screen can be scrolled using the Up and Down Arrows, rather than waiting for them to show the connection you are looking for.

Save and Load (Recall) Config

The SM-16X16-DVI-LCD and SM-32X32-DVI-LCD switches provide the ability to save and recall up to 100 switch configurations using the LCD menu. The switch configurations define the current port connections, volume control settings, and video blank status.

Note: The IRT-UNV IR Remote (page 36) can also be used to access these configurations by using the “SAVE” and

“RECALL” buttons.

To save a configuration, select “Save Config” from the main menu followed by a numeric button(s) (0-99) corresponding to the memory slot the configuration is to be saved in. Press Enter after your selection to force the current configuration to immediately be saved to the selected memory slot.

Configurations can be loaded (recalled) in much the same manner. To recall, select “Load Config” from the main menu followed by the numeric button(s) (0-99) corresponding to the memory slot from which the configuration is to be recalled. Press

Enter after your selection to immediately force the switch to change the current switch configuration to match that of the configuration recalled.

RS232 CONTROL

RS232 enables the VEEMUX to be remotely controlled via RS232. To control the VEEMUX via RS232 the user has three options:

• write a program that runs on a PC using the Command Protocol (page 13)

• use the Matrix Switcher's Control Program (page 14) provided on the CD

• use the SerTest program (page 14) provided on the CD

Remote Connection

The RS232 Interface is designed to meet the RS232C standard and can be controlled from any CPU or other controller with an

RS232 communications port. The pin-out for the RJ45 connector on the unit is as follows:

RS232 (RJ45) CONNECTOR

PIN SIGNAL FUNCTION

1 -

2 -

3 RX+ Receive data (TXD at host)

4 GND Ground

5 -

6 TX+

7 -

Transmit data (RXD at host)

8 -

A 5 foot patch cable and adapter, RJ45-to-DB9, have been provided for connection to most CPUs (see page 6). To daisy chain multiple units, connect a Matrix-Y-1 cable (sold separately) between the CPU and the first switch, and between each switch (as shown in Figure 8).

Baud Rate

The baud rate can be changed by selecting MENU on the front panel keypad, using the OSD menu, using Telnet commands

(page 16) or from the RS232 commands (page 13). The baud rate can be set to 115200, 57600, 38400, 19200, 9600, 4800,

2400, or 1200. A data protocol of 8 data bits, no parity, and 1 stop bit is used for communications. The default baud rate setting is 9600.

Unit Address and Loop Back

To allow multiple units to be controlled from a single host port, the RS232 control interface is designed to allow "daisy chaining" up to 15 units using an NTI Matrix-Y-1 cable. Connect the Matrix-Y-1 cable between the RJ45-to-DB9 serial adapter (provided with the RS232 option) and the CPU as shown in Figure 8. By setting the appropriate unit address (page 9), each unit can be given a unique address (1-15). Then the unit will only respond to commands on the bus if its address is embedded in the command.

Autostatus

When Autostatus is enabled, any output-to-input connection change in the VEEMUX will cause an Autostatus message to be sent via RS232 to the administrator. The format of the message would be "pc SW,OP:IP<CR>"

Example of an Autostatus message:

pc 01,01:04<CR> which means "At the switch with unit address 01, the output (01) has changed connection to input 04."

Notes: Message to the administrator will be delayed by any RS232 traffic being received by the switch from the

administrator.

Autostatus must be disabled before using SerTest or the Matrix Switcher's Control Program (page 14).

By default, Autostatus is disabled and must be manually enabled. Autostatus is also disabled any time the power to the

VEEMUX is interrupted.

ETHERNET CONTROL

Telnet Interface-Port 2000

The Telnet Interface enables the user to control the switch using telnet client through an Ethernet connection. The telnet server listens on ports 2000 and 2005. Port 2000 is for an operator telnet session while port 2005 (must be enabled) is intended for a software control type session (see page 17). For operator telnet control using the telnet interface and the current IP address, type the following in a command shell:

telnet 192.168.1.30 2000

The VEEMUX will prompt the user for a password. The user must enter the password followed by <Enter>.

The factory default password is "nti".

With a proper password sent the VEEMUX will respond with:

Password Successful

Connection Established

The command below are now available.

Web Interface

A user may control the connections of the VEEMUX using a Web Interface via any web browser (see page 1 for supported web browsers). With the VEEMUX connected to a LAN through an Ethernet cable, a user can access the web interface controls inside the VEEMUX.

FYI: To quickly locate a VEEMUX on the LAN and edit the IP address settings, use the Device Discovery Tool (page 35).

To access the web interface, type the current IP address into the address bar of the web browser.

Address http://192.168.1.30

To open a SSL-encrypted connection, type:

Address https://192.168.1.30

You will be prompted to accept a certificate. Accept the NTI certificate.

A "Login Page" will appear.

Figure 10- Web interface Login page

Enter the Password

The cursor will be flashing inside the username box. Enter the administrative username (this cannot be changed), then enter the default password:

User Name = root (lower case letters only)

Password = nti (lower case letters only)

To change the password, see page 31.

Note: The browser must be configured to accept cookies in order for the user to successfully make use of the web interface.

21


With a successful login, the main menu and Video Switch page will appear.

Figure 11- Main menu and Video Switch page

From the menu the user can choose from several links to either view the status of the switch or change the configuration of it. As described on the following pages, each link will enable different areas of control.

Video Switch Page

The Video Switch page (above) displays the active connections (shown in orange) and enables the user to control the video connections of the VEEMUX. Up to 100 different connection configurations can be saved and later recalled by any connection method. Scanning Sequences (page 28) for each output can also be enabled.

Note: Changes made using the keypad (page 8) or by another user through the web interface will be updated automatically to your browser every 10 seconds.

Note: Configuration 0 will be automatically loaded when the VEEMUX is powered-up.

To change a connection, click on the radio button (square image with circle in the center) that intersects the input and output columns. A black dot will be placed in the circle to indicate the selection. Then press the Submit button. The display will be reloaded with the selections changed to orange to indicate they are now active. Multiple connections can be changed simultaneously.

22


To quickly clear the selected radio buttons press the Clear Changes button. This will only work if the Submit button has not already been pressed with the selections made.

To quickly connect all outputs to a single input, click on the desired input.

FYI: See page 22 for an example of using the Outputs Scanning Sequences feature.

To save a configuraton, from the Stored Configurations user interface, use the drop-down list to select the desired slot (numbers 0-99) to save the active configuration into and press the Save button.

Note: This will save the currently active configuration on the

VEEMUX. If changes have been made in the web interface without first pressing the Submit button, those changes will not yet be part of the active configuration.

Note: If changes to the active configuration have been made by another user prior to saving the current connection selections, the changes made by the other user will be saved as the configuration.

The webpage configuration that loads after a Save is the configuration that was actually saved.

To load a saved configuration, from the Stored Configurations user interface, use the drop-down list to select the desired configuration. Then press the Load button. The VEEMUX will make the connections and the screen will refresh to show the connections associated with that configuration selection.

Alternate DNS- Enter a valid alternate Domain Name Server address if desired (not required)

This change will take a few seconds and automatically redirect the user to the IP address specified.

25


If telnet is going to be used to control the VEEMUX, place a checkmark in the “Enable Telnet” block.

If you wish to disable non-secure web access to the VEEMUX, remove the checkmark from “Allow HTTP Access”. With this box empty, only secure shell web access will be allowed.

A standard port number can be assigned for the HTTP (non-secure) and HTTPS (secure) ports, numbers ranging from 0-

65535. Default HTTP port is 80, and default HTTPS port is 443.

The Website Timeout option controls how long an inactive web connection will stay logged in. The range is 0-999 minutes (0 disables it). Any change to the Website Timeout configuration takes effect immediately.

Press the “Save” button to save any changes made.

Video Input Names

From the Administration menu, the Video Input Names page can be displayed. This page enables the Administrator to change the name of the input ports displayed on the Video Switch page.

From the Administration menu, the Scanning Sequence page can be displayed. The Scanning Sequence page displays the configuration of an automatic switching sequence from input (video source) to input for each output (monitor).

The page displays:

output number being configured

the Scanning Sequence function status for that output

the length of time in seconds (dwell time) that each input will be viewed when connected- the dwell time value ranges from 0-32000 seconds

Figure 16- Scanning Sequence page

The output selection at the top of the page can be changed to any output to display the Scan Sequence Input dwell time values for that output.

The inputs and the amount of time that each will be viewed (0-32000 seconds) can be set to cycle sequentially for each connected output. If an input is set to 0 seconds, that input will not be viewed and will be skipped from the scanning sequence. To include an input in the sequence, enter a dwell time period from 1-32000 seconds, and press “Save”.

If you make changes and change your mind and want to return the values back to what they were before changing them, press


To enable the scanning sequence for the output shown, place a checkmark in the “Sequence Enabled” block.

Tip: To quickly enable the scan sequence for multiple outputs, use the “Sequence Enable” blocks found on the Switch

Page (page 18).

Note: If only one input has a dwell time value entered, then the output connection to that input will not end when the

Scanning Sequence is enabled.

Example of using Outputs Scanning Sequences

Problem: A synchronous scan is desired for all outputs with a dwell time of 3 minutes per input, and no two outputs should be looking at the same input at any given time.

Solution:

1. Set the dwell time for all inputs listed in each output at 180 seconds (3 minutes). Press “Save” each time changes are

made to the selected output. .

2. Go to the Video Switch page (page 18) and set each output to an input of the same number (1 to 1, 2 to 2, 3 to 3, etc..).

Click on “Submit” at the bottom of the Video Switch Page to submit selections and establish a connection and starting

point for the scanning sequence. (Blocks shown in yellow in the third image indicate connections made.)

3. Click on the “Sequence Enable” box for each output (from the Video Switch Page).

4. Click on “Submit” again to begin the scanning sequence for each output.

From the moment the configuration is submitted, a synchronous scan will begin on all outputs. Each output will connect to its respective input for 30 minutes. After 30 minutes, the outputs will each switch to the next consecutive input and remain connected for 30 minutes. This cycle will continue indefinitely until sequencing is disabled.

Step 1- setup dwell times

Step 4- Click on “Submit” to begin

Step 2- setup starting point for scan and click “Submit”

Step 3- enable scanning sequences and click “Submit”

DDC Options

From the Administration menu, the DDC Options page can be displayed. DDC enables the video source to get EDID information from the display device. This enables the video source to automatically select the optimal resolution for the display by receiving, at power up, information from the display device concerning its resolution specifications.

Figure 17- DDC Options page

EDID information can be provided to the video source by the VEEMUX as follows:

Direct- (available in 8x8 models only) The video source on an input will get EDID information from the video display device that is first connected to the output, regardless of what other display devices are also connected to the video source. If the first output is switched to another input, the video source will look to the other connected outputs to get EDID information from, searching from the lowest numbered output port first.

For example: The video source on input 1 is connected to output 8, then 4, then 2, and then 5 for a total of 4 display connections. If output 8 is switched to another video source, the video source on input 1 will then get EDID information from output 2.

Default1- The video source on the input port will receive EDID information from the VEEMUX through an onboard table of values.

The values for Default 1 support computer monitors.

Default2- The video source on the input port will receive EDID information from the VEEMUX through an onboard table of values.

The values for Default 2 support televisions.

Load from Output- select the radio button for this option and enter the output number associated with the monitor that the CPU should get its EDID information from.

Once any changes are made, press “Save” to have them take effect.

Notes:

1. A Blu-Ray player, and any other video source with protective content, must use "Direct" DDC option and can be connected to only one output port at a time.

2. In order for the video sources to correctly receive the EDID information from the switch at boot-up, the switch must

be powered-up before all attached video sources.

Operation

Operation of the IRT-UNV is intuitive. The number of button presses required to complete any operation is kept to a minimum. This is accomplished using intelligent software within the NTI Matrix Switch. Additionally, the Matrix Switch allows for multiple ways for the user to complete the same operation – ensuring that the Remote will work as expected, regardless of who uses it.

Changing Ports

The first, and most important operational use of the IR Remote is changing ports of the switch. This requires the selection of both input and output ports. There are several methods of control.

Channel Surfing

The “IN +/-“ and “SCAN” buttons can be used to surf through input port connections. However, since there are multiple outputs/users, the question becomes “which output connection is being changed?” As a result, it is required that an output be selected prior to using the “IN +/-“ buttons.

The output port can be selected in two ways:

• by pressing the “OUT” button before selecting the output port number

• by pressing the “OUT” button after selecting the output port number

In both cases, the user must enter the output port number using the Numeric Keys (0-9). However, when the “OUT” button is pressed prior to selecting the port number, there will be a two (2) second delay after the last digit of the output port is entered that must expire before the output port is accepted. To avoid this delay, press the “ENTER” button to immediately accept the port number.

Once the output port has been accepted, there will be a five (5) second timeout, during which the user must press another button (“IN +,” IN -,” or “SCAN”). Each subsequent press of “IN+” or “IN-“ will renew the timeout, waiting for you to press it again (to advance or go back by one more Input channel). If no new command is sent to the switch before the timeout expires, the switch will forget the selected output, and pressing the “IN +/-“ buttons will have no effect.

All output channels can surf inputs at once by pressing the “ * “ button prior to pressing the “IN +/-“ buttons.

Examples:

Change connection of Output 1 from Input 1 to Input 3:

<OUT> + <1> + wait 2 seconds + <IN+> + <IN+>

<OUT> + <1> + <ENTER> + <IN+> + <IN+> (must press <IN+> within 5 seconds of pressing <ENTER>)

<1> + <OUT> + <IN+> + <IN+> (must press <IN+> within 5 seconds of pressing <OUT>)

38


Jump To Input

With the output port selected, a user knowing the desired input port number can enter it using the Numeric keys (0-9).

Just as with using the “OUT” button, pressing the “IN” button after the number will force the command immediately. If the “IN” button is pressed prior to the port number, the “ENTER” button must be pressed to avoid a two (2) second delay before the input port is accepted.

Examples:

Quick method to change Output 1 from Input x (any) to Input 8:

<1> + <OUT> + <8> + <IN>

Quick method to change Output 12 from Input x (any) to Input 20:

<1> + <2> + <OUT> + <2> + <0> + <IN>

Jump To Output

Users can also change ports by specifying the input port number first. Similar to selecting the output port first, the “IN” button can be pressed either before or after entering the port number. Once the input port has been selected, the output port can be selected, following the same format as “Jump to Input…”

Expiration of a five (5) second timeout will force the switch to forget the entered input port number.

Example:

Quick method to change Input 1 from Output x (any) to Output 8:

<1> + <IN> + <8> + <OUT> (must enter the <*> + <OUT> command within 5 seconds of pressing <IN>)

Connect Input to Multiple Outputs

Several displays can be connected to a single video source with a single sequence command, and the command can be entered in either of two ways:

<IN> + <mm> + <OUT> + <nn> + <OUT> + <nn> + <OUT> + <nn> + <Enter> or

<OUT> + <nn> + <OUT> + <nn> + <OUT> + <nn> + <IN> + <mm> + <Enter>

Connect a video source\input (mm) to as many displays\outputs (nn) as desired, and finish the command by pressing the

<Enter> button.

Connect All

It may be desirable to broadcast the video signals from one input to all of the outputs. In this situation, the user can quickly make all of these connections by using the “ * ” (asterisk) button which selects all outputs. With the input port selected, pressing the “ * “ button will immediately force the command to connect all output ports to the selected input.

Example :

Connect all users to Input 2:

<2> + <IN> + <*>

The “ * “ button can also be pressed prior to selecting the input port. In this case, the command will take effect once the input port has been selected.

<*> + <2> + <IN>

If no command is received before the five (5) second timeout expires, the switch will forget the “ * “ key-press.

39


Save and Recall

the 16X16 and 32X32 models). The switch configurations define the current port connections, volume control settings, and video blank status. The IRT-UNV IR Remote can be used to access these configurations by using the “SAVE” and “RECALL” buttons.

The SM-8X8-DVI-LCD video matrix switches provide the ability to save and recall up to 10 switch configurations (up to 100 in

8x8 Model

To save a configuration, press the “SAVE” button followed by a Numeric key (0-9) corresponding to the memory slot the configuration is to be saved in. Pressing a single numeric key will immediately force the switch to save the current configuration to the selected memory slot.

Configurations can be recalled in much the same manner. To recall, press the “RECALL” button followed by the numeric key corresponding to the memory slot from which the configuration is to be recalled. Pressing a single numeric key will immediately force the switch to recall the selected configuration.

16x16 and 32x32 Models

To save a configuration, press the “SAVE” button followed by Numeric key(s) 0-99 corresponding to the memory slot the configuration is to be saved in. After the numeric key(s) press the “Enter” button. If the “Enter” button is not pressed, after two seconds the function will timeout and the number entered will be saved as that configuration.

Configurations can be recalled in much the same manner. To recall, press the “RECALL” button followed by the numeric key

(s) corresponding to the memory slot from which the configuration is to be recalled. After the numeric key(s) press the “Enter” button. If the “Enter” button is not pressed, after two seconds the function will timeout and the number entered will be recalled to the current configuration.

Multiple Switch Control

All compatible NTI matrix switches will work with the same IRT-UNV IR Remote control. As a result, a user with multiple NTI matrix switches may find that, if the switches are installed too close together, both switches may respond to an IR command intended only for one switch. Or, the user may want to control multiple switches with a single remote, instead of having one remote per switch. To accommodate this situation, the IRT-UNV IR Remote provides the “SYS” button, which can be used to select the NTI switch to be controlled.

All switches will have the capability to allow the user to set the switch address (0-15). Each switch to be separately controlled must be set to a different address prior to using the Remote Control. With the addresses set, press the “SYS” button on the IRT-

UNV, followed by a two digit number corresponding to the address of the matrix switch to be controlled.

Upon accepting the “SYS” command, the switch with the corresponding address will illuminate the “IR” LED and respond to all IR Remote commands and will blink the “IR” LED on the front of the switch for visual indication. All other switches will ignore any further commands, until the “SYS” button is pressed again. To select a new NTI switch to control, press the “SYS” button again and repeat the process.

Canceling a Command

Considering the number of key presses required for some of the commands, it’s possible that the user may inadvertently press an incorrect button. Should this happen, the user can press the “ESC” button to cancel a command. Provided the command has not been accepted by the system, pressing the “ESC” button will cause the switch to “forget” or “erase” all button commands from the current command sequence. Once the command sequence has been cancelled, the user can begin entering the command again.
