Using the MKP 1000
In normal operation, the MKP 1000 is used to select an input source to be
displayed or recorded on a local video output device. Before this can
happen, at the time of installation, each MKP 1000 is programmed with a
unique address and is set to one of three operating modes:
• Room Preset Mode (Pr) – The user may select one of 10 “room
presets” programmed and made available to this room.
• Output Mode (OP) – Select one of 64 inputs to tie to this output.
• Global Preset Mode (GL) – Select one of 32 “global presets”.
With the MKP 1000, the user selects
an input or a preset from the choices
above. There may be more than one
keypad in a room. Although they
may share the same room number,
each has its own unique address (1-
64), which is normally assigned to
an output. Any changes to be made,
other than selecting an input or a
preset, are referred to as
programming and are not done by
the user. This is covered separately
on pages 3-2 and 3-3.

View Option
The MKP 1000 stores the last input number
selected from its keypad. If the View option is
On
, the number can be displayed in the LEDs
by pressing the View button. However, if the
last input was selected from another location
(the master or by RS-232 program for
example), that input number is not stored in
the MKP 1000 and pressing the View button
will not show the correct input number.
The View option is turned
on or off by the
programmer or technician
and not by the user. When
the View option is turned
Off, pressing the button
will give no response.

selection (channel or preset number)
Select an Input or a Preset
To change the input selection, see Figure
3-5a. Press the desired number on the
keypad, followed by the Enter key.
The first digit pressed (e.g., “1”) will blink
rapidly for 3 seconds. This is to allow
additional keys to be pressed, if required.
The subsequent keys must be pressed
during that 3-second interval. If not, you
must start again. (For this example, press
1, 7, Enter.) This sends a request to the
master switcher to tie input #17 to the
output device in your “room.”
If you pressed the wrong button,
or got an error, press the zero (0)
key to clear the display and then
start again.
If zero (0) is the first
key pressed,
followed by the
Enter key, this
requests a Mute
condition. Later, to
turn the mute
condition off, select
an input number and
press Enter again.

Error Display and Lockups
If communication is not made with the master unit,
trying to select an input will lock up the MKP 1000. This
will happen if the keypad is not properly connected to
the master.
If the number entered is out of range, an error code of EE
will be displayed. For a 64x64 system, The maximum
numbers are: Room preset = 10; Global preset = 32 and
Input # = 64.
