Closed circuit television (CCTV) and teleconferencing applications often require
that the audiovisual control system monitor display each camera' s position, as well
as move them to cover participants or scenes. The AXC–PTI Pan/Tilt Interface
Card mounts in an AMX CardFrame and controls voltage provided by an external
power supply to drive the pan/tilt unit in any direction. Movement commands may
also originate from computers, automatic microphone mixers and other sources,
as long as they are properly interfaced to an Axcess control system.
APPLICATION
High-current DC motor control of pan/tilt heads with 10-bit, 1,024-step resolution
•
CONTROL PORTS
Pan and tilt direct motor control from external 24 VDC max power supply, 1 A
•
Potentiometer inputs to read pan and tilt positioning
•
INCLUDES
Two status LEDs for channel 1 or 2 level change
•
One input for 12 or 24 VDC power supply
•
The AXC-VAI2 Voltage Input/Output Card provides two DC voltage outputs and
two DC voltage/potentiometer inputs. Typical applications include the control of
CCTV lenses (DC drive/pot), teleconferencing lenses (voltage reference), or small
DC motors up to 60 mA current. It may be used whenever a DC voltage ramp
and/or an analog-to-digital conversion of DC voltage or resistance is required.
APPLICATION
Low-current DC motor control of lenses or motors with 8-bit, 256-step resolution
•
Supports voltage/reference or potentiometer positioning control
•
CONTROL PORTS
Zoom and focus direct motor/reference control, -12 to +12 VDC, 60 mA
•
Potentiometer inputs to read zoom and focus positioning
•
INCLUDES
Two status LEDs for channel 1 or 2 level change
•
10 potentiometers for voltage level, range, and centering
•
Two micro-jumpers select voltage or potentiometer mode for each input channel
•
One micro-jumper selects center or low positioning on power-up

FG737
APPLICATION
24 VDC ramp control of dimmers, lenses, or small motors, 8-bit,
•
256-step resolution
CONTROL PORTS
Four DC ramp outputs, 0 to +24 VDC, 10 mA
•
Four relay channels (optional), rated at 750 mA, 28 VAC/24 VDC
•
INCLUDES
Four status LEDs for channels 1‹4 level change
•
Four groups of four potentiometers for voltage center, range for each channel
•
Certain applications require a variable low-current DC voltage to operate light
dimmers, camera pan/tilt units and motor speed controls. The AXC-VRG4
Voltage Ramp Generator Card can be programmed to provide a variable voltage
ramp from -12 to +12 VDC in 256 discrete steps. Preset positions or voltage
levels can be stored for later recall and can be sent to the four independent
outputs as required. Potentiometers are included for coarse and fine adjustment
of range and level centering. The AMX AXC-EXTN Extender Card is
recommended when on-site adjustment is desired.

•
Auxiliary DC on/off output (optional), adjustable to +12 VDC, 10 mA
•
INCLUDES
Four status LEDs for channels 1D4 level change
•
Four groups of four potentiometers for voltage center, range for each channel
