USING THE UNIMUX USB KVM SWITCH Basic Operation

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 w hich port (and corresponding CPU) is being connected to the monitor and input devices.

The UNIMUX can be controlled by four methods:

• front panel control using touch-switches and LEDs

• OSD control via the user devices (models with video support only)

• RS232 control (see page 34)

• Telnet Interface- via command line interface (page 40)

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 starting on page 20). The three MODE LEDs on the front panel indicate which mode is selected. Release the touch-switch when the LEDs indicate the de sired 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.

If the UNIMUX includes the Transparent USB option (UNIMUX-USBV-xHDUT), and if the USB Device Warning is enabled (Setting, page 18), then pressing any touch-switch on the front panel will not immediately connect the corresponding CPU to the monitor and input devices. With the first press of any touch-switch (momentary or extended), a device warning (below) will popup on the user’s monitor.

To use COMMAND, BROADCAST, or SCAN mode, we recommend that you disable the device warning first. See page 18.

Select “N” to properly eject your devices through the CPU operating system before switching ports, and then return to the OSD menu to switch ports or press the touch-switch twice more to make the change in port connection.

Select “Y” to proceed with a port change to another CPU. Any devices connected to the transparent USB ports will automatically connect to the newly selected CPU.

If a touch-switch is pressed a second time instead of just once, this device warning will be bypassed and the port change will proceed immediately.

Device warning

Keyboard Control

Keyboard control of the UNIMUX can be achieved using OSD Command Mode. Command Mode is operated using the keyboard and mouse in conjunction with OSD menus superimposed onto the monitor. For all models use the menus as instructed on page

12. By pressing <Ctrl> + < ` > (accent 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.

NTI UNIMUX SINGLE-USER HIGH DENSITY KVM SWITCH

OSD CONTROL

(OSD Control applies only to UNIMUX models with video support)

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.

Guidelines for Navigating OSD Menus

Throughout this manual, various rules apply to navigating the menus used to control and operate the UNIMUX.

• OSD menus can be navigated using the mouse, the arrows on the keyboard, hot keys (highlighted in red) and the

<Page Up>, <Page Down>, <Home>,<Tab> and <End> keys.

- The <up arrow> and <down arrow> moves the cursor up or down one line item at a time in a scrollable

window, or between menu items in a menu item list

- The <left arrow> and <right arrow> will move the cursor left or right through menu items or while in

editable fields (such as when editing port names)

- <Page Up> and <Page Down> increase/decrease the listed ports by one page at a time

- <Home> will jump to the beginning of the list

- <Tab> will jump between selectable fields, left to right

to move between menu items

- <Shift>+<Tab> will jump between selectable fields, right to left

Security Option

The security option in the OSD Control of the UNIMUX USB KVM switch 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 security features on the user port. Finally, the administrator can set a maximum idle time value after which the current user will be logged out and the login screen displayed again if the user has no activity. 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. For more on security, see page 22.

- the port is not in the Scan List

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

- the CPU connected to the port is OFF

NTI UNIMUX SINGLE-USER HIGH DENSITY KVM SWITCH

When switching to a new port the port name is displayed by OSD in the left upper corner of the monitor for 5 seconds or until a key is pressed or the mouse is moved, whichever comes first. The scan dwell time is programmable from 2 to 255 seconds (default time-out period is 5 seconds). While using the mouse, keyboard or touchscreen the scanned port becomes active and scanning is stopped. The switch will resume scanning after a period of user inactivity determined by the scan dwell time. See Settings Menu on page 18 for configuring the scan dwell time.

To return to the Settings menu, press <Esc>. The scan selection list is automatically saved.

Note: The scan dwell time set by the user affects all users. Note: The keyboard, mouse and touchscreen must remain idle for the full scan dwell time before the switch selects the

next active port.

Broadcast Mode

To activate or deactivate Broadcast Mode press <Ctrl> + from the Command Mode menu. The text shown in the menu (Figure 16) will toggle between “BCast=N” and “BCast=Y”, each time the <Ctrl> + keys are pressed. When “BCast=Y” is

shown, Broadcast Mode is active. When “BCast=N” is shown, Broadcast Mode is OFF.

Broadcast Mode enables the user to type characters to more computers simultaneously. From the Settings menu (see page 18) press to access the “Broadcast List” where the user can edit the list of ports that receive data in Broadcast Mode.

The “Broadcast List” is a check list with all the port numbers displayed

To enter the Select Language menu (see Figure 39) press K from the System Configuration menu described on page 24. Only the administrator has the Select Language menu option.

The Select Language menu enables the administrator to select a specific keyboard language (country code) to be used. Typically only SUN CPUs require a specific country code to be registered at boot up. (For other types of CPUs this feature may have no effect.) A list of available languages is displayed and can be scrolled using the mouse (scroll wheel) and/or <up arrow>, <down arrow>, <Home> and <End> keys.

• To manually program a specific language, select a langua ge and press <Enter> (or click the left mouse button).

• To automatically detect the language of the keyboard, select "AutoDetect" and press <Enter> (or click the left

mouse button) . The list will advance to the actual detected keyboard language and that language will be programmed.

Some keyboards don’t have a country code. In this case the selection will remain in the “AutoDetect” position and the default country code "00" will be programmed in the UNIMUX. If a specific country code is manually programmed, it will be the country code for the switch, regardless of the actual country code of the connected keyboard. The programmed country code is saved in memory and restored each time the UNIMUX is powered-ON. Because the CPUs that use country code (i.e. SUN CPUs) read it at boot time, it is necessary to boot the CPU(s) after programming the country code.

The baud rate value can be set to 115000, 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. With the edit field highlighted, press the <Left arrow> or <Right arrow> to change the value of the baud rate.

Note: The baud rate can also be changed from the RS232 Command Protocol (see page 34).

For more on RS232 Control, see page 34.

Figure 42- Adjust Baud Rate

Serial Address

To allow multiple UNIMUXs to be controlled from a single control terminal, the RS232 control interface is designed to allow "daisy chaining" up to 15 units. Each unit must be assigned a unique address. The unit address for the UNIMUX can be changed by pressing <E> from the System Configuration menu. With the edit field highlighted, press the <Left arrow> or <Right arrow> to change the value of the unit address. The address range is 1-15. For more on daisy chaining, see page 34.

NTI UNIMUX SINGLE-USER HIGH DENSITY KVM SWITCH

SUN RAY SUPPORT

The UNIMUX fully supports SUN Ray CPUs, however, a lac k of horizontal mouse movement may be experienced. If this occurs, enable MAC mode (page 24) for the port that the SUN Ray is connected to. This should enable proper mouse movement.

RS232 CONTROL

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

• write a program that runs on a PC using the Command Protocol (page 36)

• use the NTI Switch Control Program (page 37) provided on the CD

• use the SerTest or RMTEST programs (pages 37 and 39) 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 - 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 8 - No connection

NOTE: Security must be disabled or user access granted on the port(s) to be selected by RS232 control.

A 5 foot patch cable and two adapters, RJ45-to-DB9 and RJ45-to-DB25, have been provided for connection to most CPUs (see page 9). 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 45).

Baud Rate

The baud rate can be changed using the OSD menu (page 34) or from the RS232 commands (page 36) . The baud rate can be set to 115000, 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.

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 and the CPU as shown in Figure 45. By setting the appropriate unit address (page 34), 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 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 (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 NTI Switch Control Program (below).

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

FIRMWARE UPGRADE PROCEDURE

This procedure describes how to upgrade the firmware in this UNIMUX switch. If you are not certain whether this UNIMUX has the most up-to-date firmware available, see page 51 for instruction on how to determine what versi on the UNIMUX has. All versions of firmware can be downloaded from the NTI firmware download website at http://www.networktechinc.com/download/d-

srvsw-usbu-hd.html ,

The UNIMUX switch has 3 types of micro-controllers:

1. Main User Controller – there is only one on each UNIMUX and it will be upgraded with a binary file.

¾ For switch models with the Transparent USB ports (i.e. UNIMUX-8HDUT) the file will be named unimux-suhdt-csx-x.bin (where x-x is the rev number). ¾ For switch models without the Transparent USB ports (i.e. UNIMUX-8HD) the file will be named unimux-suhd-csx-x.bin (where x-x is the rev number).

Note: Earlier models of UNIMUX that had the extra USB port for specific devices (i.e. UNIMUX-8HDU) will use the firmware version for models without Transparent USB ports.

2. HID Port Controller – there is one HID Port Controller for each CPU port available o n the switch – it will be upgr aded with an

Intel hex file named unimux-suhd-cpkmx-x.hex. Each CPU port is upgraded independently.

3. Vendor Specific Port C ontroller – there is o ne such controller for each CPU port available on the switch – it will be upgraded

with an Intel hex file named unimux-suhd-cpvdx-x.hex. Each CPU port is upgraded independently.

The UNIMUX firmware has a bootloader which can be used for fi rmware upgrades. The bootloader resi des in a protected area of Flash memory, so that if the upgrade fails for any reason, the bootloader will still be available to be used to re-program the entire unit.

Upgrades can be made to the User Controller, HID Port Controller, or V endor Specific Port Controller on an individual basis as needed. Not all CPU ports must be at the same revision level for the UNIMUX to work, but it is highly recommended that if you upgrade one CPU port, you upgrade all CPU ports on a switch.

Requirements

¾ CAT5 Patch Cable (supplied with UNIMUX) ¾ RJ45-DB9 or DB25 Adapter (supplied with UNIMUX) ¾ Computer with a Terminal Console (for example, HyperTerminal in Windows, or any similar program able to send files using

Xmodem protocol)

¾ Firmware files for the UNIMUX on the computer with the Terminal Console.

Figure 48- Preparation for firmware upgrade

2. Power ON the computer only. Open the terminal console and apply the following settings to the terminal console for the port connected to the UNIMUX:

Baud rate: 57600 Data bits: 8 Parity: none Stop bits: 1 Flow control: none

NTI UNIMUX SINGLE-USER HIGH DENSITY KVM SWITCH

Upgrade Procedures

Start the Bootloader

In the HyperTerminal window on the attached computer, press and hold the <Tab> key and power ON the UNIMUX. The following message (or one similar) will be displayed on the screen:

UNIMUX-HD-NxM Bootloader Revision: 1.1 Date: 2008/09/11 15:40:16 Copyright (C) Network Technologies Inc.

Press <H> for help… >

Release the <Tab> key.

The “>” prompt indicates that the bootloader is waitin g for commands. The available commands are composed by sending one ASCII character. To send a command to the bootloader, type t he key in the terminal window that corresponds to the desired command. The available commands, listed below, can be viewed by typing <h> or <H> (the Help command) from the keyboard.

Note: Commands can be typed using upper or lower case letters.

Commands:

-------------h, H – Display list of commands x, X - Exit Bootloader u, U – Upgrade user controller firmware p, P – Upgrade HID port controller firmware v, V – Upgrade vendor specific controller firmware s, S – Read Checksum of the HID port controller firmware t, T - Read Checksum of the vendor specific controller firmware

NTI UNIMUX SINGLE-USER HIGH DENSITY KVM SWITCH

Update the User Controller Firmware

Note: The User Controller Firmware update only needs to be done once, whether the UNIMUX switch is a single-user, or a multi-user model.

The user controller firmware comes as a file in binary format and has the extension .bin. (i.e. filename.bin). To upgrade the user controller to this file, press from Terminal window. The following message should appear on the screen:

Erasing flash memory… Memory successfully erased Send .bin file using Xmodem protocol..

At this point the binary file unimux-suhd-csx-x.bin must be sent. To do this, from HyperTerminal:

1. go to “Transfer” menu in the Menu Bar of the HyperTerminal window

2. click the item “Send File …”

3. in the dialog box which pops up on the screen, browse for the file to be sent and select it

4. select “Xmodem” from the Protocol drop-down menu

5. press “Send” button

The transmission will start shortly. Wait until the transmission is finished. There will be some pauses during transmission, since the processor writes blocks of 4KB.

When the transmission is complete, the HyperTerminal window should show the following status message and return to the menu prompt:

Device successfully programmed!

To exit from the bootloader, press <x>.

Update the HID Port Controller Firmware

The HID port controller firmware comes as a file in Intel Hex format and has the extension .hex (i.e. filename.hex). To upgrade any of HID controllers (there is one per CPU port) with this firmware, press from the terminal window. The following message should appear on the screen:

Send .hex file using XModem protocol...

At this point, the hex format file unimux-suhd-cpkmx-x.hex has to be sent, using HyperTerminal and the same procedure as before. When the transmission is done, the following message will be shown in the HyperTerminal window:

File transfer OK! Please, type the two-digit number of the port to be updated, <A> to program all or <X> to exit (the two-digit number should be between 01 and nn, where nn is the number of available ports):

NTI UNIMUX SINGLE-USER HIGH DENSITY KVM SWITCH

To program only one device (CPU port), the corresponding port number must be typed (two-digit number, zero leading, number

between 01 and the last CPU port number, depending on switch size. To program all devices, just press <a>).

The following message will be shown on the screen (it may take about 12 seconds to program each device):

Programming device, please wait...

Device ID: 0x001E Device successfully programmed!

The bootloader will then ask again for a port number. To program another port, type the two-digit number of the port, To exit from this function and the bootloader, press <x>.

If <a> was pressed instead of a single port number, and all devices were programmed, the message above will be re peated for each port that was programmed. After all are programmed, unless the switch has 32 CPU ports, the following message will be shown on the screen

Programming device, please wait...

Device ID: 0x0000 Device failed! Error Code 1

This is shown because the bootloader continues to look for devices until it has found up to 32 (the maximum number of possible CPU ports a single UNIMUX can have). If it doesn’t find another port, the procedure will fail and discontinu e. On switches with fewer than 32 ports, this is normal.

To exit from the bootloader, press <x>.

Update the Vendor Specific Port Controller Firmware

Updating the vendor specific port controller firmware is similar to updating the HID port controller firmware (described on page 3). The only differences are that key <v> is used to enter this command and the hex file to send will be unimux-suhd-cpvdx-x.hex

To exit from the bootloader, press <x>.

NTI UNIMUX SINGLE-USER HIGH DENSITY KVM SWITCH

Read the Checksum of HID or Vendor Specific Port Controller Firmware

Reading firmware checksum is useful to determine the version of software running on port controllers. While the firmware revision for user controller can be found on the UNIMUX splash screen when it is powered-ON, the firmware revision of port controllers is not displayed anywhere. Reading checksum is an easy way to identify the current firmware revision in your UNIMUX and to determine if a new firmware revision is available for download.

To read the checksum, type <s> for HID port controllers or <t> for vendor specific port controllers, at the bootloader prompt. The following message will be displayed:

Please, type the two-digit number of the port to be checked, <A> to check all or <X> to exit (the two-digit number should be between 01 and nn, where nn is the number of available ports):

To read the checksum for only one device, type the number of the port (two digits, leading 0). To read the checksum for all ports type <a>.

The device ID and the checksum will be displayed in the following format:

Device ID: 0x001E Device Checksum: 0x3AB1

The checksums for all revisions of UNIMUX firmware can be found on the NTI download webpage at

http://www.networktechinc.com/download/d-srvsw-usbu-hd.html ,

To exit from the bootloader, press <x>.
