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
Every unit comes standard with all control methods built-in. An IRT-UNV-IR Remote Control is required to use the Infrared
option. No software is involved (see Infrared Control on page 41). 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 24), 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:
Key Functions:
Up Arrow- Scroll up the menu
Down Arrow- Scroll down the menu
Left Arrow (Enter Key)- Select the menu item
List - Open the menu, or exit the menu (also used to back
out of the menu, one step at a time)

LCD Menus
Serial Menu
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 45).
Ethernet Menu
Under “Ethernet” menu are several parameters:
1- Mode
2- IP Address
3- Mask
4- Gateway
5- Pref. DNS
6- Alt. DNS
The Mode parameter will let you select between a manual IP setting, a DHCP assigned dynamic IP address setting, or disabling
the Ethernet port. 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.

DDC Menu
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.
Under the “DDC” menu are five parameters:
1- Chose Input (Choose Input)
2- All Inputs
3-FacDefault1
4-UsrDefault1
5-ReloadOptn
1) Choose Input- select the EDID information source for each input individually, or
2) All Inputs- select EDID information source for all inputs at once.
Within these sections you will need to select between:
default 1- the inputs will get EDID information from a predefined table in the VEEMUX supporting 1080p resolution
default 2- the inputs will get EDID information from a predefined table in the VEEMUX supporting UHD resolutions
From Out (?)- select which Output port the Input will get EDID information from regardless of which output it is
connected to
DDC Mix(?)- select which Input will receive EDID information that is common to the Outputs selected on the “DDC Mix”
page (page 36) for that input
3) FacDefault1- Select this to use the factory default EDID data for DDC “Default 1” configuration
4) UsrDefault1- Select this to replace the EDID information stored in the VEEMUX for “Default 1” with the EDID data from the
monitor presently connected to Output 1.
5) ReloadOptn- Select this and choose to enable or disable this feature. When enabled, the switch will refresh DDC data
stored in the VEEMUX each time the VEEMUX is power-cycled. The DDC data will be based on the current DDC configuration
settings.
Standby
The fourth option in the main menu is ”Standby”. When Standby is selected, 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 42), or
3) the “Disable Standby” button is pressed in the web interface (page 38)
Save and Load (Recall) Config
The SM-16X16-HD4K includes 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 41) 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 four options:
write a program that runs on a PC using the Command Protocol (page 12)
use the Matrix Switcher's Control Program (page 13)
use the SerTest program (page 14)
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 - No connection
2 - No connection
3 RX+ Receive data (TXD at host)
4 GND Ground
5 - No connection
6 TX+ Transmit data (RXD at host)
7 - No connection

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 13).
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
(telnet must be enabled- see page 26) listens on ports 2000 and 2005. Port 2000 is for an operator telnet session while port 2005
is intended for a software control type session (see page 18 for more on Port 2005 control). 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 (for Port 2005 control, substitute “2005” for “2000” in this command)
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 commands below are now available.
