Chapter 1

Introduction

Overview

The KH1508i / KH1516i KVM Switches are control units that allow access to multiple computers from a single KVM (keyboard, monitor, and mouse) console.

A single KH1508i / KH1516i can control up to 8 / 16 computers. As many as 15 additional KH1508 / KH1516 switches can be daisy chained from the original unit, so that up to 256 computers can all be controlled from the original KVM console.

Note: Aten ACS1208 / ACS1216 switches can also be installed on a KH1508i

/ KH1516i daisy chain.

Since the KH1508i / KH1516i uses TCP/IP for its communications protocol, it can be accessed from any computer on the Net - whether that computer is located down the hall, down the street, or half-way around the world.

Over the

NET

Local

In addition to TCP/IP connectivity, the KH1508i / KH1516i provides KVM ports for a locally attached PS/2 console – allowing access and control from the data center as well as over the Net. The switches utilize a single shared bus implementation – although they support local and remote login at the same time, they do not support independent operation. If a local user logs in while a remote user has already opened a session, the local user sees the same screen that the remote user is working on.

KH1508i / KH1516i User Manual

For local access, the KH1508i / KH1516i supports resolutions of up to 1600 x 1200, as well as 1280 x 1024 @ 75Hz for an extended distance of up to 40 m. For remote access, the switches support up to 1280 x 1024 @ 75Hz.

The switches feature RJ-45 connectors and CAT 5 cable to link to the computers. Utilizing PS/2, USB, and serial KVM Adapter Cables for the final linkup, the KH1508i / KH1516i permits any combination of PCs, Macs, Sun computers, and serial devices to coexist on the installation. Use of the adapter cables dramatically reduces cable clutter, and makes reconfiguring the installation easy and convenient.

A custom ASIC (patent pending) provides an auto-sensing function that recognizes the position of each station on the chain, eliminating the need to manually set the position with DIP switches. A seven segment front panel LED displays each Station's position for easy identification.

The KH1508i / KH1516i has been designed to work seamlessly with the ALTUSEN CC1000 Control Center Over the NET™ for ease of access and administration. It also allows the IP address configuration to be easily configured from the local console OSD.

Your KH1508i / KH1516i investment is protected by a firmware upgrade utility. You can stay current with the latest improvements in functionality by downloading firmware update files from our website, and using the utility to quickly and conveniently install them.

Setting up the KH1508i / KH1516i is fast and easy; plugging cables into their appropriate ports is all that is entailed. Because the KH1508i / KH1516i intercepts keyboard and mouse input directly, there is no software to configure; no need to get involved in complex installation routines; no need to be concerned with incompatibility problems.

Access to any computer on the installation is easily accomplished--either by pressing front panel port selection switches; entering hotkey combinations from the keyboard; or by means of a powerful menu driven OSD (On Screen Display) system. A convenient Auto Scan function also permits automatic scanning and one-by-one monitoring of the activities of selected computers.

There is no better way to save time and money than with a KH1508i / KH1516i installation. By allowing a single console to manage up to 256 computers, a KH1508i / KH1516i installation: (1) eliminates the expense of having to purchase a separate keyboard, monitor, and mouse for each; (2) saves all the space those extra components would take up; (3) saves on energy costs; and (4) eliminates the inconvenience and wasted effort involved in constantly moving from one computer to another.

Daisy Chaining

Up to 15 additional KH1508 / KH1516 KVM switches can be daisy chained down from the KH1508i or KH1516i. As many as 256 computers can be controlled from a single console in a complete installation.

Note: Aten ACS1208 / ACS1216 switches can also be installed on a KH1508i

/ KH1516i daisy chain.

To set up a daisy chained installation, do the following:

1. Use a daisy chain cable set to connect the Chain Out port of the parent unit

to the Chain In port of the child unit (First Station Out to Second Station In, Second Station Out to Third Station In, etc.).

Note: 1. The KH1508i / KH1516i doesn’t have a Chain In port since it is

the highest level parent – it only has a Chain Out port.

2. Daisy chain cable sets require a separate purchase – see your dealer for details.

3. The KH1508i / KH1516i does not support distances that exceed 100m between the first station and the last station.

2. Use Cat. 5 cable to connect any available KVM port to a KVM Adapter Cable that is appropriate for the computer you are installing (see KVM Adapter Cables, page 5 for details).

Note: The switches do not support distances that exceed 40 m between

themselves and the KVM Adapter Cable.

3. Connect the KVM Adapter Cable to the computer. Refer to the installation diagram on the previous page for details.

4. Use the power cord supplied with this package to connect the KVM switch to an AC power source.

5. Repeat steps 1–4 for any other switches you want to add to the chain.

6. Power up the installation according to the following procedure: a) Power up the First Station. Wait for the unit to ascertain its Station ID

and display it on the Station ID LED. (The Station ID for the First Stage unit is 01, the ID for the Second Stage unit is 02, the ID for the Third Stage unit is 03, etc.)

b) Power on each station in turn (Second S tation, then Third Station, etc.).

In each case, wait for the Station ID to be ascertained and displayed before powering on the next station.

c) After all the Stations are up, power on the computers.

Basic Operation

Port Selection

KH1508i / KH1516i installations provide three methods to obtain instant access to any computer in your installation: Manual, OSD, and Hotkey.

Manual

For manual port selection, simply press the Port Switch that corresponds to the device you wish to access.

OSD

OSD (On Screen Display), provides a menu driven interface to the computer switching procedure. The KH1508i / KH1516i provides two OSD systems: A text-based OSD when you log in from a local console; and a graphical OSD when you log in remotely over the internet. Local console OSD operation is discussed in the next chapter; graphical OSD operation is discussed in Chapter 7 (for Windows logins) and Chapter 8 (for Java logins).

Keyboard Hotkeys

Hotkeys allow you to conveniently provide KVM focus to a particular computer from the local console keyboard, instead of having to manually select them by pressing Port Selection switches. See Keyboard Port Operation, page 34, for details.

KH1508i / KH1516i User Manual

Hot Plugging

The KH1508i / KH1516i supports hot plugging – components can be removed and added back into the installation by unplugging and replugging their cables from their ports without the need to shut the unit down. In order for hot plugging to work properly, however, the procedures described below must be followed.

Hot Plugging Stations

You can switch station positions by simply unplugging from the old parent and plugging into a new one. After you do, in order for the OSD menus to correspond to the change, you must reset the OSD. See RESET STATIO N IDS, page 29, for details.

Hot Plugging KVM Ports

After switching KVM ports, in order for the OSD menus to correspond to the change, you must manually reconfigure the OSD information for the new Port information. See F3 SET, page 26, and the Port Setting selections under the F4 ADM function, page 29, for details.

Note: If the computer’s Operating System doesn’t support hot plugging, this

function may not work properly.

Hot Plugging Console Ports:

Keyboard, monitor, and mouse can all be hot plugged. When hot plugging the mouse:

 You may un plug the mouse and plug it back in again (to reset the mouse,

for example), as long as you use the same mouse.

 If you plug in a different mouse, all the stations and all the computers on

the installation must be shut down for 10 seconds, then restarted following the Power Up Sequence described under Step 6 on page 16.)

Note: If, after hot plugging (or at any other time), there is no response to

keyboard and/or mouse input, perform a Keyboard and Mouse Reset by pressing in the Reset switch (see page 7).
