NTI KEEMUX Series PS/2 KVM Switch OSD CONTROL (Optional) 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.
NTI KEEMUX Series PS/2 KVM Switch User Login Mode (Cont'd) Function: Submit user name/password Exit User Login Mode and return to previous mode. This function is only available if security is not currently active. Keystroke: Enter If the password submitted is incorrect, the user will not be able to proceed. If the password submitted is correct, the user will proceed to the maintenance menu for additional feature options. Esc .
NTI KEEMUX Series PS/2 KVM Switch System Access List The System Access List displays a list of numbers representing the ports so the administrator can change access rights to the ports for the selected user. The user’s name is displayed at the top of the access list. The mouse is used to change access rights by clicking on a given number to toggle a port’s status. A user that has access to a port can connect to that port and control the CPU connected to that port when in Normal Mode.
NTI KEEMUX Series PS/2 KVM Switch OSD Command Mode (Cont'd) Function: Keystroke: Sets scan time-out on each port Ctrl Selects a specific port Ctrl Enters Search Mode and adds a character to search string and selects the CPU’s name that matches best. A-Z 0-9 + T - + P - (0-2) x (0-9) x - (0-9) x - (0-9) x - (0-9) x (xxx from 002 to 255. ie. t002 would set the time-out period for 2 seconds) (Pxx would be P01, P02, etc.
NTI KEEMUX Series PS/2 KVM Switch Broadcast Mode (Use with extreme caution or commands intended for one CPU will be sent to all CPUs) Broadcast Mode allows the operator to send keystrokes to all active CPUs simultaneously (even those CPUs the user cannot connect to due to lack of security access ). To enter Broadcast Mode press + from Command Mode. Broadcast Mode is indicated by the illumination of the BROADCAST LED on the front panel. The BROADCAST LED will remain ON while in Broadcast Mode.
NTI KEEMUX Series PS/2 KVM Switch Search Mode Search Mode allows the user to enter and maneuver through a list of CPU names. As the user types, the best matching CPU name is selected. The list of CPUs may also be searched for a specific (or similar) name. From Command Mode, type any alphabetical or numeric character to enter Search Mode. The following commands are valid when the search option has been invoked from Command Mode.
NTI KEEMUX Series PS/2 KVM Switch Maintenance Mode (Cont’d) Function: Keystroke: Make OSD window taller T Make OSD window shorter S Change user password.

NTI KEEMUX Series PS/2 KVM Switch Unit Address and Loop Back To allow multiple units to be controlled from a single CPU 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 table below to set the unit address.
NTI KEEMUX Series PS/2 KVM Switch Command Protocol Host controller commands supported by the unit are defined below. Notes: • All commands should be terminated with an (ASCII 13) denoted by . When a command is sent, the entire string is echoed back to the CPU along with a response from the addressed unit as shown in the command definitions. Unit response will be sent within 500 msec after . • Use a program that will send an entire command line all at once, not character by character.

NTI KEEMUX Series PS/2 KVM Switch HOW TO DISABLE OPERATING MODES The operating modes of the KEEMUX can be disabled if a user desires to do so. The Command Mode can be disabled which would also disable the Scan and Broadcast Modes, or, the Scan and/or Broadcast Modes can be individually disabled leaving the other features in Command Mode enabled. To disable these operating modes, the user must get access to the jumper block.
NTI KEEMUX Series PS/2 KVM Switch NOTE: Before proceeding, it is important to discharge any static charge you may be carrying by touching any large metal object (away from the KEEMUX). 4. The first visible circuit board, the uppermost board, is the video board. Along the back of the video board are between 3 and 5 video ribbons (depending on how many monitors the unit is designed to connect to) connecting the video board to a circuit board on the rear panel with 15HD connectors on it.
NTI KEEMUX Series PS/2 KVM Switch Configuring The Jumper Block Once the jumper block is exposed, apply a jumper across the appropriate pins to disable the desired mode(s) according to the chart below. Pin Designation Mode KCMD Command Mode* BRDC Broadcast Mode SCAN Scan Mode *Note: Putting a jumper across pins KCMD to disable Command Mode will also disable Broadcast and Scan Modes. If the unit has an LCD this jumper will be here.
NTI KEEMUX Series PS/2 KVM Switch AUDIO SUPPORT (Optional) Audio support provides the following additional features: • Audio signals from the same CPU that keyboard, mouse, and video signals are from can be received by the user. • Audio inputs accept any standard line level audio (1Vrms or 2.5Vp-p). • Audio outputs are capable of driving an 8 Ohm speaker load with 200mW of continuous RMS power.
NTI KEEMUX Series PS/2 KVM Switch TROUBLESHOOTING If the KEEMUX is not working properly, please look for a solution in the list below: PROBLEM: SOLUTION: Keyboard Errors Check cable connections on each CPU and the switch. PROBLEM: SOLUTION: No Video Check cable connections on each CPU and the switch. Verify that keyboard, video, and mouse connect from each CPU to matching ports. After reconnecting, the CPU may need to be re-booted in order to sense the monitor connection.
