NTI UNIMUX SERIES USB KVM SWITCH

USING THE UNIMUX DVI 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 USB Device 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

• RS232 control (page 13)

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 "Command Mode" below). 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 Command Mode (below). The keyboard can be used to control all functions of the UNIMUX as an alternative to using the front panel on the UNIMUX.

By pressing <Ctrl> + < ` > (accent/tilde key), the user can enter Command Mode. 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.

Command Mode

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

` `

~ (ACCENT/TILDE

KEY)

When the COMMAND LED is illuminated, all 3 status lights on the keyboard will illuminate (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:

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.

Scan Mode

To activate Scan Mode press <S> from the Command Mode menu. When in Scan Mode the switch scans to each port with a

CPU powered-ON. (The SCAN LED on the front panel will illuminate and 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 <B> from the Command Mode menu. (The BROADCAST LED on the front panel will illuminate and remain ON while in Broadcast Mode.) Broadcast Mode enables the user to type characters to all powered-ON CPUs simultaneously.

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

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

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.

11

NTI UNIMUX SERIES USB KVM SWITCH

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 the 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

Note: If any SUN CPUs are connected to the UNIMUX, they must be rebooted. Keyboard configuration is only read by

SUN CPUs on startup.

For more on international SUN keyboards, see page 19.

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 10), 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.

Unit Address and Loop Back

To allow multiple units to be controlled from a single CPU serial port, the RS232 control interface is designed to allow "daisy chaining" up to 15 units. By setting the appropriate RS232 DIP switches, 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. Use the following table to set the unit address.

Note: The "loop back" RS232 DIP switch (RS232 DIP switch 1) should be ON for each unit in the chain.

Note: Switch 4 on the RS232 DIP switch is not used.

In order to connect multiple switches (up to 15) with RS232 connections to the same CPU, an NTI Matrix-Y-1 cable must be used.

Connect the Matrix-Y-1 cable between the RJ45-to-DB9 serial adapter (provided with the RS232 option) and the CPU as shown in

Fig. 11.

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.

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 NTI Switch Control Program or SerTest to control the

UNIMUX via RS232 (see page 16).

If the first field is not a known command (as listed above) or SW field is different from the unit address programmed at the DIP switch (page 13), 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.

KEYBOARD FEATURES

The keyboard configuration of each CPU is saved in the UNIMUX. For example, if the CPU attached to Port 2 had CAPS LOCK and NUM LOCK selected the last time that CPU was accessed, then they will automatically be set when that CPU is accessed again.

Keyboard-To-Computer Translation

(See Fig. 14 on page 19 for reference.)

The UNIMUX enables a mixture of otherwise incompatible peripheral computer components to be connected together. This is accomplished by performing keyboard-to-computer translations automatically (i.e. translate a MAC keyboard and mouse to a

Windows type CPU). The chart below shows the capabilities of devices controlling certain CPU types.

Figure 14- 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 connected to the UNIMUX

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

3. Power-ON the CPU connected to the UNIMUX

It is also 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 the international keyboard identification number to the CPU by following the instruction on page 12.
