AXC-PTI

Pan/Tilt Interface Card

(requires high power DC supply)

FG768

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

AXC-VAI2

Voltage Output/Analog Input Card (2 voltage outputs, 2 analog inputs)

FG737

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

AXC-VG24

Voltage Ramp Generator Card (24 VDC)

FG736

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

AXC-VRG4

Voltage Ramp Generator Card (12 VDC)

FG735

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.

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
