Power-Up Sequence

• The UNIMUX can be powered at any time.

• The CPUs can be powered at any time although if a CPU needs a keyboard and/or mouse at power-ON it should be powered

after connecting to and powering-ON the UNIMUX.

• USB input devices (keyboard and mouse) can be hot plugged to and from the UNIMUX at any time.

Immediately after powering ON the UNIMUX, the following splash screen will appear on the monitor if the OSD option is built into the switch:

If the security option is enabled (see page 12 for details on the "Security Option"), when the UNIMUX is powered up the user will be prompted for a username and password to continue. If the security option is not enabled the monitor will display the desktop image for the connected CPU and the user can continue with normal operation of the connected CPU.

Limitations

• Only USB input device or hub cables can be connected to the UNIMUX at the USB Type A female ports labeled "DEVICES". (See Features and Functions on page 3, item 11.)

• A USB hub (single or multi-port) can be used provided only USB input devices are plugged into it.

• Only a USB Windows or SUN keyboard or USB mouse may be connected to the USB port on a USB MAC keyboard

• A maximum of 8 input devices may be connected to the UNIMUX either directly or through hubs.

See Fig. 7 for some examples of input device combinations that can be used with the UNIMUX.

USING THE UNIMUX USB KVM SWITCH

Once the UNIMUX is properly connected, the UNIMUX will enable a connection to be made between the CPUs attached to its VIDEO and CPU ports and the monitor and input devices attached to the MONITOR and DEVICES ports. The LEDs on the control panel of the UNIMUX will illuminate depending on which port (and corresponding CPU) is being connected to the monitor and input devices.

The UNIMUX can be controlled by three methods:

• front control panel using touch-switches and LEDs

• keyboard control through Command Mode

• mouse clicks from within some menus of OSD Command Mode (optional).

Front Panel Control

There is a touch-switch and LED on the front panel of the UNIMUX for each CPU the switch will connect the monitor and input devices to. Pressing any touch-switch on the front panel of the UNIMUX will connect the corresponding CPU to the monitor and input devices. Holding down any front panel touch-switch for more than 2 seconds will cause the UNIMUX to cycle through all modes of operation including COMMAND, BROADCAST, SCAN, and NORMAL (described in "Basic Command Mode" on page 8 and in "User Access Functions" starting on page 15). The three MODE LEDs on the front panel indicate which mode is selected. Release the touch-switch when the LEDs indicate the desired mode. When no mode LEDs are illuminated the user is in Normal Mode controlling directly the CPU to which the user is connected through the UNIMUX.

Keyboard Control

Keyboard control of the UNIMUX can be achieved using either of two methods:

• Basic Command Mode- operated strictly by using keyboard commands as instructed below. Basic Command Mode is only applicable if the OSD option is not built into the switch.

• OSD Command Mode (optional)- operated using the keyboard and mouse in conjunction with OSD menus superimpos ed

onto the monitor. If OSD is built in, use the menus as instructed on page 12.

By pressing <Ctrl> + < ` > (accent key), the user can enter Command Mode (either Basic, or OSD). Once in Command Mode, typing a series of commands will cause the UNIMUX to connect the user to any one CPU connected to the switch. Pressing the <Esc> key will exit Command Mode.

NTI UNIMUX SERIES USB KVM SWITCH

MODES OF OPERATION

Basic Command Mode

In order to control the UNIMUX with the keyboard connected, Command Mode must be enabled. To enter Command Mode from the keyboard:

Press

Ctrl

NOTE: IF THE OSD FEATURE HAS BEEN INSTALLED, PROCEED DIRECTLY TO “OPTIONAL OSD CONTROL” ON PAGE 12. If not, continue on this page.

When the COMMAND LED is illuminated, all 3 status lights on the keyboard will illuminat e (if they aren't already due to caps lock, scroll lock, and/or num lock) to indicate that Command Mode is enabled and the following functions are available:

Basic Command Functions

Function: Keystroke:

FYI: The user must exit Command Mode to type to a CPU. To exit Command Mode, either hold down any touch-switch on the

front panel for more than 2 seconds, OR press <ESC> on the keyboard.

(Pxx would be P01, P02, etc.)

(xx= 01-32 <M> + <0> + <1> will enable function on Port 1 <M> + <3> + <2> will enable function on Port 32. Keyboard LED's will flash once to confirm command. )

(xx= 01-32 <W> + <0> + <1> will disable function on Port 1 <W> + <3> + <2> will disable function on Port 32. Keyboard LED's will flash once to confirm command. )

Scan Mode

When in Scan Mode the switch scans to each port with a CPU powered-ON. (The SCAN LED on the front panel will illuminate a nd remain ON while in Scan Mode. ) The port with the CPU powered-ON remains active while in use until it becomes idle for the configured dwell time (default time-out period is 5 seconds) before switching to the next powered-ON CPU port. See Command Mode section above for configuring the scan dwell time.

Note: The keyboard and mouse must remain idle for the full scan dwell time before the switch selects the next active port.

Broadcast Mode

To activate Broadcast Mode press <Ctrl> + <B> from the Command Mode menu. Broadcast Mode enables the user to type characters to more computers simultaneously. From the Change Settings menu (see

page 18) the user can edit the list of ports that receive data in Broadcast Mode. A port doesn’t receive broadcast data if one of the following conditions is true:

- the port is not in the Broadcast Mode list

- Security Mode is enabled and the user does not have access rights to the port

NOTE: The user must type somewhat slowly when in Broadcast Mode (less than 20 wpm) and cannot use the <Backspace> key.

Normal Mode

When all of the UNIMUX mode LEDs are OFF the user is in Normal Mode, controlling the CPU to which the user is connected through the UNIMUX.

No Sun Sleep Mode

PLEASE NOTE: It is necessary to configure a Sun CPU (most versions) such that the Sleep Mode is not enabled. If the Sun CPU goes into Sleep Mode either automatically or manually, the user must reboot the Sun CPU in order to resume use of the Sun CPU.

To disable the Sleep Mode, perform the following steps:

1. Select "Power Manager"

2. Look for "Device Idle Time Before Power Saving Starts"

3. Select "Always ON"

4. Look for "Override Device Idle Time For:"

5. Make sure neither "Monitors" nor "Disks" are selected.

Select Country Code

It is possible to configure the UNIMUX to emulate a specific international Sun keyboard regardless of what actual keyboard is connected. This is recommended when the CPU needs the layout code (i.e. a SUN CPU) and the keyboard doesn't have an explicit layout code (i.e. some Windows keyboards). To do this, manually set the UNIMUX to indicate th e international keyboard identification number to the CPU using the following procedure;

1. Connect the keyboard to be used to the UNIMUX

2. Enter Command Mode

3. Type Lxx, where xx is the number from the list below that corresponds to the desired country code

4. Exit Command Mode

5. Reboot the CPU connected to the UNIMUX

NTI UNIMUX SERIES USB KVM SWITCH

Mice and Trackballs with MACs

The UNIMUX can be configured to enable full functionality between mice and trackballs having two or more buttons and USB MAC CPUs. By default, the ports on the UNIMUX are configured for use with WINDOWS and SUN CPUs and have no special translation for using multi-function mice and trackballs when a MAC CPU is connected. Using the commands <M> + <x> + <x> (xx = port number), or <W> + <x> + <x> in Command Mode (page 8), either enable or disable this feature as needed for each port.

NOTE: Be sure to re-configure port for connection to a WINDOWS or SUN CPU if a MAC CPU is removed and a WINDOWS or SUN CPU is then connected.

NTI UNIMUX SERIES USB KVM SWITCH

OSD CONTROL

OSD superimposes a menu system on the user’s video screen with a list of all connected CPUs. OSD allows CPUs to be named (with up to 12-character names). OSD then allows selection of CPUs by that name. Connected CPUs can be listed by name or by port number. OSD Search Mode enables the user to type in the first few characters of the CPU's name and the OSD will locate it. Help screens assist with all OSD functions.

Security Option

The security option of the OSD Control enables an administrator to control access to CPU ports for each user. Up to 63 users can be created. These users have controlled access to any CPU. Only the administrator can activate or deactivate the secur ity features. Security can be activated from the Maintenance Mode menu (page 22) with a successful administrator login for verification purposes. Furthermore, the administrator can set a maximum idle time value after which the current user will be logged out and the login screen displayed. This time out does not function while the OSD is active. The current security status, idle time out, and scan dwell time are all saved and will be restored whenever power to the switch is cycled OFF, then ON. To reset the administrator's password call NTI and have the device serial number of the UNIMUX available.

Enabling the Security Feature

To enable the security feature the administrator must first enter Command Mode from the keyboard using the se quence <Ctrl> + <`> (accent key). The OSD menu will automatically appear on the monitor in addition to illuminating the Command Mode indicator LED on the UNIMUX. This provides a visual way to control the UNIMUX using the keyboard and mouse.

The administrator , when setting the USB KVM switch up for the first time, may want to proceed directly to the

ADMINISTRATION Mode by typing <CTRL> +<M> , then <A>, and then <Y>. The factory settings are:

• default user name = ADMINISTRATOR

• default password = ADMINISTRATOR

Note: The user name for the administrator cannot be changed from "ADMINISTRATOR".

FYI: Capital letters are introduced by keeping the <Shift> key pressed while typing. The <Capslock> does not work while in OSD.

Once logged-in, follow the instructions on page 14 for setting up users and changing the password. Once the password is setup, if it is lost or forgotten the administrator will have to contact NTI for assistance on clearing the password and set it up again. Within the Administration Mode the administrator can setup each of the users and the limitations of their use of the individual CPUs attached to the switch.

Figure 9- Administrator Login screen

When a standard user powers up the system a security screen will appear if security has been enabled by the administrator. The user will need to login to the switch by following the instructions on page 13 for the USER LOGIN. If the

user does not know the appropriate user name and password (setup by the administrator), contact the switch administrator for this information. Once logged-in a user can follow the Command Mode functions described on page 16 to control the switch within the limitations as determined by the administrator.

Note: The Alternate Command Hot Key does not replace the <`> (accent) key, it just works as another way to enter into Command Mode. After setting it, the user can enter into Command Mode either with <Ctrl> + <`> or with <Ctrl> + <Alternative Command Hot Key> combination. To disable it, the administrator should set <`> as the Alternate Command Hot Key.

USER ACCESS FUNCTIONS

Introduction

The OSD menu enables a user to name the CPUs connected to the UNIMUX and conne c t to them using that name from a single keyboard and mouse. The OSD is positioned on the user's monitor, displaying 8 CP U names at a time. The screen can be used for switching as well as editing the CPUs’ names. Through the OSD menu, the user can operate the UNIMUX to have the switch cycle through 3 extended modes of operation: COMMAND, BROADCAST, and SCAN . Three LEDs on the front panel indicate when these modes are enabled.

OSD Command Mode

When entering the Command Mode from the keyboard using the <Ctrl> + <`> (accent key), the OSD menu will automatically appear on the monitor in addition to illuminating the COMMAND indicator LED on the USB KVM switch. This provides a visual way to control the UNIMUX.

The list below describes the OSD Command functions available from the keyboard after enteri ng Command Mode and while the COMMAND LED is illuminated:

RS232 CONTROL

(Optional)

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

• write a pro gram that runs on a PC using the Command Protocol (page 26)

• use the Matrix Switcher's Control Program (page 27) provided on the CD

• use the SerTest program (page 27) provided on the CD

RS232 Connections and Configuration

Remote Connection

The RS232 Interface (optional) is designed to meet the RS232C standard and can be controlled from a ny CPU or other controller with an RS232 communications port. The pin-out for the DB-9 connector(s) on the unit is as follows:

RS232 CONNECTOR (DB-9 FEMALE)

PIN SIGNAL FUNCTION

1 CD Carrier Detect 2 TXD Transmit data (RXD at host) 3 RXD Receive dat a (TXD at host) 4 DTR Data terminal ready 5 GND Signal ground 6 DSR Data set ready 7 RTS Request to send 8 CTS Clear to send 9 - No connection

Note: Security must be disabled or user access granted on the port(s) to be selected by RS-232 control.

On the DB-9 female connector, pins 1 (DCD), 4 (DTR), and 6 (DSR) are shorted and pins 7 (RTS) and 8 (CTS) are shorted. Therefore, host handshaking is bypassed and TXD and RXD are the only active signals. A straight through DB-9 cable (not null modem) will work for most CPUs. To daisy chain multiple units, a Matrix Y-1 cable is used (see page 24) for each UNIMUX in the chain. The last unit will have no connection on its output port and should have DIP switch 1 ON (see table under "Unit Address and Loop Back" on page 25).

Baud Rate

The baud rate can be changed by powering down the unit, changing the 8 position RS232 dip switch on the front of the UNIMUX, and then powering back up. This table shows how to set the baud rate.

Unit Address and Loop Back

To allow multiple units to be controlled from a single CPU serial port, the RS232 con trol interface is designed to allow "daisy chaining" up to 15 units. By setting the appropri ate RS23 2 dip switches, each unit can be given a unique address (1-1 5) . T hen t he unit will only respond to commands on the bus if its addr ess is embedded in the command. Use the table below to set the unit address.

Command Protocol

RS232 commands supported by the unit are defined below. All command strings should be terminated with a <CR> (carriage return). When a command is sent, the entire string is echoed back along with a response from the addressed unit as shown in the command definitions. All characters in the command string should be upper case, and all numbers below 10 should have a leading 0 (ex: 1 = 01). As command strings are sent, the inner character delay cannot exceed 500 milliseconds.

Figure 29- RS232 Communication Illustrated

Note: To use this command protocol, the user is required to write a program that will send an entire command string all at once, not character by character. Programs that send one character at a time (such as HyperTerminal) cannot be used to control the UNIMUX. Alternatively, the user may use the Matrix Switcher's Control Program or SerTest to control the UNIMUX via RS232 (see page 27).

Legend: (All numbers must be two digits) SW : Switch (01-15) (Unit Address)

OP : Output (User) Port (01) IP : Input (CPU) Port (01-MAXINPUTS) <CR> : Carriage Return (Hex 0xD)

Note: For units with one output (user) port, use 01 for the output selection.

switch (page 25), the command will be ignored. If the SW field corresponds to the unit address, but if the syntax is wrong after this field, the switch will answer with a bad response ?<CR>.

Autostatus

When Autostatus is enabled, any output (user) -to-input (CPU) connection change in the UNIMUX 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 (User) (01) has changed connection to input (CPU) port 04."

Note: An Autostatus message to the administrator will be delayed by any RS232 traffic being received by the switch from the administrator.

By default, Autostatus is disabled and must be manually enabled.

Figure 30- Keyboard Layouts

International Sun Keyboards

The UNIMUX can recognize international layouts for Sun keyboards. In order to use an international Sun keyboard, follow this procedure:

1. Power-OFF the CPU from the UNIMUX

2. Connect the international keyboard to be used to the UNIMUX

3. Power-ON the CPU to the UNIMUX It is also possible to configure the UNIMUX to emulate a specific international Sun keyboard regard less of what actual keyboard is

connected. This is recommended when the CPU needs the layout code (i.e. a SUN CPU) and the keyboard doesn't have an explicit layout code (i.e. some Windows keyboards). To do this, manually set the UNIMUX to indicate th e international keyboard identification number to the CPU by following the instruction on page 9 (for switches without OSD feature) or on page 19 (for switches with OSD feature).

NTI UNIMUX SERIES USB KVM SWITCH

CASCADING

The UNIMUX-USBV-x USB KVM switch can be cascaded as shown in Fig. 31 below. Single user and multi-user UNIMUX switches may be connected downstream (see Figs.33 and 34). The first switch in a cascaded system is referred to as the "master", while all downstream switches are referred to as "slaves". The only additional hardware requi red to cascade switches is a set of device and monitor cables for each “SLAVE UNIT” (see MATERIALS on page 1). All CPUs and switches can then be controlled by users using OSD commands with Command Mode.

Notes:

• The UNIMUX USB KVM switch must have OSD installed to use cascading.

• Cascading is not an option in the UNIMUX-USBV-2 2 port USB KVM switch

• If the UNIMUX-USBV-x is connected in a cascaded system with earlier UNIMUX-USBV-x switches (product mad e

prior to 10-1-04), then the dipswitches must be configured as indicated on page 30 and REXT-SR-xx cab les must be used as shown in figure 28.

• Slaves in a cascaded system must be either all single-user switches or all multi-user switches, but not a

combination of both.

Configuration

In a cascaded system with single-user switches as slaves, if all switches being cascaded were made on or after 10-1-04, then no additional configuration is necessary. If any single-user switches in the cascaded system were made prior to 10-1-04, then all units must be configured using the 6-position dip switch (located on the front of each unit) according to the tables on page 32 (Table 1 and Table 2).

A cascaded system using multi-user switches as slaves requires no additional configuration.

Cascaded Installation

a. Follow the instruction under Configuration above before proceeding. b. Using the 15HD video cable ends of a USBVEXT-xx-MM cable, connect the USB KVM slave's MONITOR port to the master’s VIDEO 1 port. c. Using the USB ends of the same USBVEXT-xx-MM cable, connect one of the USB slave’s USB DEVICES ports to the master’s CPU 1 port.

Note: Only one of the two ports labeled DEVICES on a slave needs to be used in order for cascading to work.

d. Repeat step b. & c. for each additional slave, keeping in mind that each slave will connect to the next available master’s port (i.e. Slave #2 to master’s VIDEO 2 & CPU 2, etc.) See Fig. 33 on page 33. e. With a RMT extension cable, connect the master’s DAISY OUT port to slave #2’s DAISY IN port. Then connect slave #2’s DAISY OUT to slave #3's DAISY IN. Continue until all slaves are connected together.

Figure 32- Cascaded configuration with multi-user slaves

FYI: Any USER and MONITOR ports on a multi-user switch connected as a slave that do not get connected to the master can be connected to by users (for example users 5-8 in Fig. 30). Users connected to a slave downstream from the master will control only the CPUs directly connected to that slave switch (i.e. users 5 and 6 in Fig. 32 above can only control CPUs 25-40).

Note: All UNIMUX-USBV-x switches must be powered OFF during dip-switch configuration Note: Dip-switches only need to be configured if one or more slave switches was made prior to 10-1-04. Otherwise, all

switches should be OFF.

These switch settings (Table 2) enable the slave to establish its identity (i.e. location in the group) to the Master.

Side Note: In a Master, the same switches are used to configure the Master for how many slaves are attached to it.

NTI UNIMUX SERIES USB KVM SWITCH

Limitations

¾ If any switches made prior 9/22/04 are used as slaves, then all switches used as slaves must have the same number of CPU

ports (all 4, 8, or 16 CPU ports).

¾ Up to 8 slaves may be connected to form a maximum system size of 152 ports (1x32 port master + 8x1 6 port slaves). ¾ Slaves must be added to the master in order (slave #1 to master’s port 1, slave #2 to master’s port 2, etc).

FYI: Master Port 1 (with an 8-port Slave connected to it) will become ports 1-8 (1-4 for a 4-port slave). Master Unit Port 2 (with a second 8-port Slave Unit connected) will become port numbers 9-16 (5-8 for a 4-port slave).

¾ All UNIMUX-USBV-x switches must be powered OFF during dip-switch configuration. ¾ The front panel buttons are only used to o perate standalone switches. To control a cascaded network of switches, only the

OSD commands within Command Mode will be recognized.

Note: Cascading is not an option in the UNIMUX-USBV-2 2 port USB KVM switch.

TROUBLESHOOTING

PROBLEM: SOLUTION:

Keyboard Errors Check cable connections on each CPU and the switch.

No Video Check cable connections on each CPU and the switch. Verify that keyboard and video connect from each CPU to matching ports. After reconnecting, CPU may need to be re-booted in order to sense the monitor connection.

No Mouse Movement Check cable connections of mouse. Verify that mouse driver was loaded.
