AD1684B DESCRIPTION
DESCRIPTION
The AD1684B Receiver is used with American Dynamics
Matrix Switching Systems to control pan, tilt, zoom, focus,
iris, and auxiliary functions at a camera site. This Receiver is
classified as a dual channel type, since two independent control
channels are supplied. The AD1684B will control two
cameras with no auxiliaries or one camera with auxiliaries.
The output voltage of this unit is 24 VAC.
Receivers obtain control instructions via the common code
lines originating directly from a Matrix Switching System or
an intervening Code Distribution Unit. To enable each
Receiver to identify those control signals intended for it, each
Receiver must be set up at installation to identify the camera
number with which it is to be associated.
In systems over 64 cameras the numbers are block-related, i.e.,
System camera #1 is camera #1 in Block #1, System camera
#65 is camera #1 in Block #2, System camera #129 is camera
#1 in Block #3, etc.
As delivered, the AD1684B is a two-channel controller for
Pan/Tilt and Lens control of two separate cameras. The
channels are designated as Channel A and Channel B.
Channel A always controls the drive motors of a Pan/Tilt and
motorized Lens units. Channel B has a selectable output to
control either the drive motors of a second Pan/Tilt and Lens
or four auxiliaries. The auxiliary outputs are provided as two
latching or two momentary controls.
FEATURES
Pan/Tilt and Lens Control
As delivered, each channel of the Receiver provides drive
outputs at 24 VAC for control of Pan/Tilt motors and 10 VDC
output for Lens control. One ten-pin connector contains all the
connections required for control of the Pan/Tilt and Lens.
Note: Certain Pan/Tilt units require alternate voltages
other than those noted in this manual. If desired,
call the Technical Support Center for information or
assistance (1-800-442-2225).
Table 1 - Pan/Tilt and Lens Ratings
FUNCTION VOLTAGE CURRENT
PAN MOTOR 24 VAC 2.4 Amps (note 1)
TILT MOTOR 24 VAC 2.4 Amps (note 1)
IRIS MOTOR 10 VDC .05 Amps
FOCUS MOTOR 10 VDC .05 Amps
ZOOM MOTOR 10 VDC .05 Amps
Note: Total of all 24 V Pan/Tilt motor currents and Auxiliary
currents (both channels combined) is not to exceed 2.4
Amps. Continuous current for each Pan/Tilt or
Auxiliary output must not exceed 1.5 Amps.
Auxiliaries
If configured for auxiliary operation (Setup, page 2), the
AD1684B Receiver provides two latching and two momentary
outputs. These 24 Volt outputs may be used to operate user
controlled devices, provided that the total current for Pan/Tilt
and Auxiliaries does not exceed 2.4 Amps.
Auxiliary loads are subject to the same constraints as if the
channel was set for Pan/Tilt operation.
Preset Scene
This optional feature allows the operator to save a pre-selected
scene (pre-positioned scene) and recall the scene upon
keyboard command. The programmed scene is stored at the
Receiver and is backed-up in the event of a power failure.
The number of presets allowed by the Receiver is determined
by the Matrix Switching System. Refer to the Matrix
Switching System installation and operation manuals for
programming procedure.
The placement of jumper J9 determines whether the presets are
enabled. All units are factory set with the presets enabled.
