Page 5: Introduction
The KEEMUX PS/2 KVM switch (KEEMUX) enables access to several IBM PC-AT, PC-AT Clone or PS/2 CPUs from one monitor, keyboard and PS/2 mouse (up to 32 CPUs as a single switch or 152 CPUs when switches are cascaded). These CPUs can be file servers, network managers, etc. -

FYI: Should switch 7 or 8 get changed to the “ON” position, it will be necessary to power-down the entire system (including CPUs), change the dip-switches back to the “OFF” position, and then power the system back up. If it is necessary to replace one PS/2 keyboard with another one, the keyboard can be hot-swapped without powering-down. -

NTI KEEMUX Series PS/2 KVM Switch Connect the keyboard cable to the 6 pin miniDIN female port labeled “KEYBOARD” on the rear panel of the switch. Connect the mouse cable to the 6 pin miniDIN female port labeled “MOUSE” on the rear panel of the KEEMUX. -
Page 9: Power Up
CASCADING The KEEMUX switch can be expanded to access up to 152 CPUs by cascading multiple units together, as illustrated below. The KEEMUX connected to the monitor and keyboard must be configured as the “master unit" (via dip-switches). Any switches connected to the master unit must be configured as “slave units". -
Page 10: Configuration
NTI KEEMUX Series PS/2 KVM Switch Configuration All 4, 8, and 16-port units are configured using the 8-position dip-switch (located on the front of each unit) according to tables 1 and 2 below. Front Panel Configuration Switches Table 1 * (default settings) -

Front Panel Control There is a touch-switch and LED on the front panel of the KEEMUX for each connected CPU. Pressing any touch-switch on the front panel of the KEEMUX will connect the selected CPU to the keyboard, monitor, and mouse. -
Page 12: Keyboard Control
Exit Command Mode If the SCAN LED is ON, pressing → or ← will cause the switch to select the next active port. NOTE: The “port” mentioned in the “Command Functions” above refers to the combination of the video (VIDEO x), mouse and keyboard (CPU x) of like numbers that a CPU is connected to (i.e. -
Page 13: Scan Mode
When in Scan Mode the KEEMUX scans 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. When the switch becomes idle for the configured time-out period (default time-out period is 5 seconds) the switch will connect to the next powered-ON CPU port. -
Page 14: Osd Control
This time out does not function while the OSD is active. 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. -

NTI KEEMUX Series PS/2 KVM Switch User Login Mode (Cont'd) Function: Keystroke: Submit user name/password Exit User Login Mode and return to previous mode. This function is only available if security is not currently active. Additional Modes Available With Security NOTE: The three modes that follow are only available if the administrator is logged in. -
Page 16: System Access List
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. -
Page 17: Scan Mode
Scan Mode 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.) To enter Scan Mode press <Ctrl> + <S> from Command Mode. The port with the CPU powered-ON remains active while in use. -
Page 18: Broadcast Mode
Edit Mode Edit Mode allows the user to modify the names of the CPUs connected to the switch. Names of CPUs can be up to 12 characters in length. To enter Edit Mode press <Ctrl> + <E> from Command Mode. When in Edit Mode, multiple keystroke combinations are not valid (<SHIFT>+<P>, <CTRL>+<P>, <ALT>+ <P>, and <P>... -
Page 19: Search 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. -

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 <Enter> (ASCII 13) denoted by <CR>. 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. -

If the unit is in a plastic case, the digital board is located on the bottom of the case, requiring the user to partially disassemble the unit to gain access to the jumper block. For models KEEMUX-Px in a plastic case: 1. Make sure the KEEMUX is completely disconnected from all CPU components. -

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. -
