NTI KEEMUX Series PS/2 KVM Switch
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. Internal microprocessor driven circuitry allows all CPUs to be booted simultaneously and
error free with only one keyboard and mouse present. Port selection is accomplished through front panel push buttons or
commands typed on the keyboard. Port status LEDs continuously update on the front panel of the switch.
Available Options
• Switch models are available in 60 or 50 Hz, and 110 or 220V.
• OSD -On Screen Display feature will superimpose operating menus directly onto the monitor for security administration and
control. Add "-O" to the part number (i.e. KEEMUX-Px-O)
• RS232 support for alternative control using RS232 connection
• Audio support to enable user to connect stereo speakers to receive audio signals from connected CPUs- add "-A" to the part
number (i.e. KEEMUX-Px-A)
• Dual Video option supports CPUs with two video outputs. Add "-DV" to the part number (i.e.KEEMUX-Px-DV)
• DDC Support- for use with DDC enabled monitors. Add "-D" to the part number. (i.e. KEEMUX-Px-D)
See our catalog, visit our website at http://www.networktechinc.com, or contact an NTI sales representative at 800-742-8324 (800-
RGB TECH) or 330-562-7070 for more details.
Limitations
• The KEEMUX Px KVM switch is compatible with PS/2 mice and PS/2 CPU ports ONLY. Serial mice cannot be adapted for
use with the KEEMUX Px KVM switch.
• Serial ports on CPUs require the NTI VOPEX-IM9D for use with this switch.
Add "-RS" to the part number (i.e. KEEMUX-Px-RS)

INSTALLATION
Prepare To Connect
1. Before connecting the KEEMUX to the CPUs, make sure all CPUs, the monitor, and the KEEMUX are turned OFF.
WARNING! DAMAGE MAY OCCUR TO THE CPU IF POWER IS NOT DISCONNECTED BEFORE CONNECTING OR DISCONNECTING
!
CABLES.
2. The dip-switches on the front panel are configurable for several tasks. Switches 1-6 are used for cascading actions (see
CASCADING on page 5) and switches 7 and 8 are for keyboard configuration. These keyboard configuration switches come
pre-configured with both in the “OFF” position. Do not change these settings, as this will cause the PS/2 keyboard to not
work.
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.
Refer to Fig. 1 for instructions on proper keyboard dip-switch configuration.

2. Connect the keyboard cable to the 6 pin miniDIN female port labeled “KEY BOARD” 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.
Figure 3- Connect the user keyboard and mouse
3. Connect each CPU to the keyboard, monitor and mouse ports using VEXT-xx-MM for the monitor and VKEXT-xx-MM (2) for
the mouse and keyboard– REQUIRED (not supplied). See Fig. 4.
• Group the keyboard, monitor and mouse interface cables from each CPU.
• Make sure that cables from the first CPU are connected to the VIDEO 1 and CPU 1 MOUSE and KEYBOARD
connectors.
• Cables from the second CPU should connect to the VIDEO 2 and CPU 2 MOUSE and KEYBOARD connectors...etc.
NOTE: If an AT style keyboard connector is on a CPU, insert an
adapter cable (ADP-5D6MD-R) between the CPU and VKEXTxx-MM cable.

Power Up
1. Turn the KEEMUX power ON first. The mode LEDs on the KEEMUX should flash twice.
2. Turn the monitor power ON.
3. Turn any or all of the CPUs ON.
FYI: Do not press any port buttons on the front panel until the PORT 1 light on the front panel illuminates.
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". All KEEMUXs are fully configurable for this expansion method.
The only additional hardware required is a set of keyboard, monitor, mouse, and RMT extension cables for each slave unit (see
Fig. 5 below).

Limitations
a. All the slave units must be the same size.
b. Only 4, 8, or 16-port switches can be used as slave units.
c. Up to 8 slave units may be connected to form a maximum system size of 152 ports (1 x 32 port master + 8 x 16 port slaves).
d. Slave units must be added to the master unit in order (slave #1 to master’s port 1, slave #2 to master’s port 2, etc.).
FYI: Port 1 of the master unit (with a 4-port slave unit connected to it) will function and be controlled as ports 1-4 (1-8 for
an 8-port slave, 1-16 for a 16-port, etc.). Port 2 of the master unit (with a second 4-port slave unit connected) will
function and be controlled as port numbers 5-8 (9-16 for an 8-port slave, 17-32 for a 16-port slave, etc.). See Fig. 6 on
page 6.
e. All units must be powered OFF during configuration and interconnecting.
