1 FEBRUARY 00 KVA Serial Computer Interface Module for ServSwitch Summit. Introduction If you want to use your ServSwitch Summit system (KV00A series of product codes) to access a CPU or other device through an RS- port, attach a serial computer interface module ( CIM, product code KVA) to the device s serial port as described in Section. The KVA CIM is designed to emulate an ASCII terminal, converting keyboard input to RS- data input and converting RS- data output for display on a VGA monitor. This conversion allows any device that can be accessed by an ASCII terminal to be operated with a user station attached to your Summit system, across an end-to-end distance of up to 00 ft. (. m) as opposed to the normal RS- maximum of 0 ft. (. m). Here are some of the KVA s useful features: It maintains eight pages of data in a circular buffer. In its Buffer Edit Mode (see Section.), you can edit data, copy it, mark it, and/or resend it to the computer or other device. In its On-Line Mode (see Section.), you can operate the ASCII device as if it were attached to a text terminal. It has twelve programmable keys for frequently performed character-string commands (see Section ). You can directly attach a local PS/ or Sun user station (keyboard and monitor) if necessary (see Section ).

2 SERIAL CIM FOR SERVSWITCH SUMMIT. Installation Take these steps to attach a KVA CIM to the serial port of a computer CPU or other device and to your Summit system:. Run an appropriate cable from the KVA s DB female DTE connector to the device s serial port. The type of cable will depend on what type of connector the port is and whether it s pinned as DTE (for a data source/ destination such as a CPU) or DCE (for a data-communicating device such as a modem). Here are the product codes of some cables we recommend if the port is: DB male DTE (most PCs, some routers, etc.): EVMBMC-000 for a -ft. (.-m) cable; DB male DTE (some older PCs, routers, etc.): EYN0-000-MF for a -ft. (.-m) cable; DB female DCE (many external modems, muxes): BC000 for a -ft. (.-m) cable. If the device has some other type of serial port, call Black Box Technical Support.. If you need temporary crash cart access or permanent local control, you can attach a local user station (consisting of a keyboard and VGA monitor only) to the KVA. The user station s keyboard can be either be PS/ or Sun type; a Sun keyboard will require a special setting in the Setup Screen see Section ). To install a local user station, plug a PS/ keyboard into the KVA s -pin mini-din connector, or a Sun keyboard into its -pin mini-din connector. Plug a VGA monitor into the KVA s HD connector. NOTE This local station will contend for keyboard control with the remote user stations attached to Summit USMs based on a fixed one-second activity timeout. As soon as there has been no keyboard activity from the local station for one second, a remote station can take keyboard control, and vice versa.. Plug in and turn on the device. If possible, set it to communicate at 00 bps, data bits, no parity, and stop bit. (These don t have to be the permanent serial settings, but the device must be set this way to establish initial communication with the KVA; later you can configure both the device and the KVA to better settings see Section. If the device can t be configured for these settings, you ll need to temporarily attach a CPU or other device that can be.)

3 SECTION : Operation. Plug the KVA s power supply into the KVA and a working AC outlet. If the KVA and power supply are installed and operating properly, the KVA s green LED will start blinking: once per second while the CIM is idle, more quickly while it s passing data in either direction.. Connect one end of a CAT UTP cable (not included, we recommend product code EYNMS) to the RJ- port on the KVA. Connect the other end of the cable to RJ- channel port # on the back of one of your Summit Base Units, or to the RJ- port on the back of a USM if you want Direct Mode access (see Appendix B of your ServSwitch Summit Base Unit manual). If the CIM is installed properly and the attached device or port is configured correctly, you re ready to start using the CIM for your serial communication.. Operation. SCREEN LAYOUT The KVA produces eight-color video at 00 x 00 resolution, which can accommodate lines of 0 text characters each. A typical ASCII terminal uses lines, so the KVA uses the eight extra lines to provide system-status and help information. As shown in Figure, these eight lines are divided so that four are at the top of the screen and four are at the bottom: In line of the top pane, the KVA s firmware version is displayed at the right. In line of the top pane, the cursor position and buffer-page number are displayed at the left and the terminal type and data rate are displayed at the right. In line of the top pane, the communication status is displayed in the center. This status can be: On Line : The KVA is communicating with the computer and displaying the interactions in its terminal-screen area; Help : [Alt] + [F] has been pressed, so the Help screen is being displayed; Set Up : [Alt] + [F] or [Alt] + [F] has been pressed, so the KVA is in Setup Mode; or Buffer Edit : [Alt] + [F] has been pressed, so the KVA is in Buffer Edit Mode.

4 SERIAL CIM FOR SERVSWITCH SUMMIT In addition, the access type is shown at the right of line of the top pane. The access type can be either LOC (the local keyboard/monitor user station is active), RMT (a remote Summit user station is active), or NO (there is no current user-station activity the KVA is idle and will grant keyboard and mouse control to the first user station that attempts to assert it). The four lines in the bottom pane display command keys specific to the current screen Black Box Corporation Copyright 00 V.0 ASCII Terminal Converter, Model: KVA Line 0 Position 0 Page VT00 00 Baud Status: On Line RMT # Login: Huimin Password: Terminal-screen area ( lines x 0 characters) <Alt-F> = Display Help Menu Screen <Alt-F> = Set Up Programmable Keys <Ctrl-Break> = Reset Serial Communication and KVA <Ctrl-s>/<Ctrl-Q> = Stop/Resume output from Computer <Alt-F> = Setup serial communication <Alt-F> = Review/Edit Buffer Figure. KVA screen layout (an On-Line Mode session shown).

5 SECTION : Operation. ON-LINE MODE When you operate the KVA in On-Line Mode (see Figure ), the main screen area displays your interactions with the ASCII device, as if it were the screen of an ASCII terminal. Simultaneously, the data stream being output by the device is stored in an eight-page circular buffer, so you can not only access and operate the device, but you can also review its historical data as needed. Because the buffer is circular, it always retains the most recent eight pages of data from the device; the newest data will overwrite the oldest data. Conveniently, you may program any of the PC keyboard s twelve function keys to trigger your most-often-used data-stream commands (see Section ). Pressing any key you ve set this way causes the Summit to send the corresponding command to the device. During the online session, you can also send any of the following key combinations (press and hold [Ctrl] or [Alt], press and release the command key, and release [Ctrl or Alt]) to control your communication with the device or to access the KVA s help and setup screens: [Ctrl] + [Break] (the [Pause/Break] key next to the [Scroll Lock] key): Resets both the KVA and the serial communication with the device. [Ctrl] + [S] (not case-sensitive): Sends an X-OFF command to the device to temporarily stop it from sending any data; until the flow is allowed to resume, all output data will be queued by the device. (If the device doesn t support X-ON/X-OFF flow control, this command has no effect.) [Ctrl] + [Q] (not case-sensitive): Sends an X-ON command to allow the device to resume sending data after being halted by the [Ctrl] + [S] command. [Alt] + [F]: Displays the Help screen shown in Figure. [Alt] + [F]: Displays the Setup screen shown in Figure. [Alt] + [F]: Displays the Set Up Programmable Keys screen shown in Figure. [Alt] + [F]: Switch to Buffer Edit Mode, as shown in Figure.. BUFFER EDIT MODE The KVA stores the most recent eight pages of data from the attached ASCII device in a circular buffer. After you switch the KVA from On-Line Mode (see Section.) to Buffer Edit Mode by pressing [Alt] + [F], you can review the contents of the buffer by moving the cursor with the arrow keys, [PageUp], [PageDown], [Home], and [End]; see Figure. You can also edit the data in the buffer with [Insert], [Delete], [Backspace], and the other keys listed in the Help screen in Figure.

8 SERIAL CIM FOR SERVSWITCH SUMMIT. Configuration Press [Alt] + [F] to bring up the Setup screen, shown in Figure, where you can select your desired serial-communication parameters (baud rate [data rate], etc.) and type of local video output. The initial parameters will always start at their factory defaults, so make sure that the serial port or device to which the KVA is attached is temporarily configured for 00 bps, data bits, no parity, and stop bit. (If the port or device can t support all of these settings, you must temporarily attach one that can.) Also, if you want to perform initial configuration with a local user station, it must consist of a PS/ keyboard and VGA monitor. Available data-rate ( Baud Rate ) settings are 00, 00, 00, and,00 bps. You can select even, odd, or no ( None ) parity; or data bits; and or stop bits (but data bits requires stop bits). The terminal type is fixed at VT00. To force local VGA output even when your local keyboard is a Sun type, access the KVA from a user station with a PS/ keyboard and a VGA monitor. Bring up the Setup screen and change the video option for Sun keyboard to VGA. You can then access the KVA from Sun type user stations Black Box Corporation Copyright 00 V.0 ASCII Terminal Converter, Model: KVA Line 0 Position 0 Page VT00 00 Baud Status: Set Up RMT Baud Rate : 00 Parity : None Data Bit : Stop Bit : Terminal Type : VT00 ASCII Terminal Converter Setup Screen Video Output: PS/ Keyboard: VGA Only Sun Keyboard: Sun Composite Set up: Default Use <Tab>/<Shift-Tab> to go to a field to edit Use < > or < > to change parameter in a field <Esc> to return to On Line <Alt-F> = Display Help Menu Screen <Alt-F> = Setup Screen <Alt-F> = Set Up Programmable Keys <Alt-F> = Review/Edit Buffer <Ctrl-Break> = Reset Serial Communication and KVA Figure.

10 SERIAL CIM FOR SERVSWITCH SUMMIT. Troubleshooting. THINGS TO TRY If you don t get a device prompt:. If the KVA s screen is displayed on your monitor with the top and bottom help windows, make sure that it indicates On Line status. If not, press [Esc] to return to On-Line Mode.. Make sure that the KVA and the attached device are both receiving power. The KVA s power supply should be securely connected to both the KVA and a working outlet. Its LED (next to the -pin mini-din PS/ mouse connector) should flicker quickly if data is being transmitted and blink once per second at other times.. Make sure that the cable between the KVA and the device is securely attached at both ends.. Make sure that the serial-communication settings of the KVA match those of the device. Press [Alt] + [F] to check the KVA s settings in its Setup Screen. If you don t get any video or the video is degraded or distorted:. Make sure that all of your cables are connected securely.. Make sure that your monitor can handle 00 x 00 video resolution at a refresh rate of 0 Hz.. If you re at a remote user station s monitor, make sure that you aren t trying to run CAT cable too far end-to-end. The total length of CAT cabling from the serial device to the monitor shouldn t be greater than 00 ft. (. m).. If you re using a Sun keyboard at the local user station, the KVA will, by default, try to output legacy Sun compatible composite video on its HD connector. You ll need to temporarily attach a PS/ keyboard, press [Alt] + [F] to bring up the Setup Screen (see Section ), and change the video setting so that the KVA outputs VGA video even when a Sun keyboard is attached. 0
