3.0 DESCRIPTION
As the name implies, the MPT9008PZ/CZ Coaxitron
Switcher/Controller is a unit that provides both a Con-
troller and Switcher in the same electronics package.
(Reference Figure 1.) The integration of these dual
functions into one package combines the functionality
of the Coaxitron transmitter/controller and the conve-
nience of an 8-input passive switcher with loop-through
capabilities. The transmitter/controller provides up to
16 remote control functions without the need for control
cables other than for a dedicated video cable for the
normal transmission of a remote camera signal to the
local monitoring and control position. The MPT9008PZ/
CZ lends itself to application in situations where short-
to-medium distances are involved.
Typically, these 16 transmitter/control functions can
be grouped as follows:
PTZ FUNCTIONS
1. Pan Left 5. Zoom In
2. Pan Right 6. Zoom Out
3. Tilt Up 7. Focus Near
4. Tilt Down 8. Focus Far
CAMERA/LENS FUNCTIONS
9. Iris Open 11. Camera Power On/Off
10. Iris Close 12. Auto/Manual Scan
Functions 1 through 10, 15 and 16 are momentary; that
is, they are only actuated while the associated control
switch located on the Coaxitron Switcher/Controller
front panel is operated. Functions 11, 12, 13 and 14 are
latching; that is, camera power, auto scan, and auto/
manual iris are latching functions and remain on until
turned off. The latching iris function is not dedicated,
and with proper interfacing, it can be used for some
other latching function. Alternately, AUX 1, 2, 3 and 4
may be used as momentary functions to control such
things as lights or gates with proper external interfacing.
Up to ten functions can be operated simultaneously.
Functions 11 through 16 must be used individually;
although any one of these functions may be used simul-
taneously with functions 1 through 10. These control
functions are active and control only the camera posi-
tion that is currently selected by the push buttons (1-8)
on the front panel of the unit.
The switcher portion of the MPT9008CZ/PZ provides
a convenient, inexpensive and reliable method of switch-
ing up to 8 video inputs, one at a time, to a single monitor
output. All switching is accomplished utilizing inter-
locked manual push buttons. The number on each push
button corresponds to the video input BNC on the rear
of the unit; i.e., push button #1 corresponds to video
input #1, etc. When any push button is depressed, the
corresponding video input is displayed on the monitor
and coax control functions are enabled for that camera
position.
AUXILIARY FUNCTIONS
