Specifications

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 requir
ed. Potentiometers are included
for coarse and fine adjustment of range and level centering.
The AMX AXC-EXTN Extender Card (FG760) is recommended
when on-site adjustment is desir
ed.
APPLICATION
• 12 VDC ramp control of dimmers, lenses, or small motors, 8-bit,
256-step resolution
CONTROL PORTS
• Four DC ramp outputs, -12 to +12 VDC, 10 mA
• 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
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 ar
e 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 cur
r
ent. 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 dir
ect 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
