System Application
The AXB-EM232 is an AMX Enhanced System Master Card in a single compact
enclosure. It is fully compatible with the AXCESS Control System and can be used
either as a stand-alone device or with other AMX bus controllers. The AXB-EM232
runs complete AXCESS programs and controls other AXlink components and two
devices using RS-232 as a control protocol. It can also control devices using RS-422
or RS-485 protocols.
The standard program configuration of this Camrobotics system application
(Figure 2) controls up to six camera stations. An AXB-CAM, CAM-1000, and PS2.8
are required for each station. There is also a provision for RS-232/422 interfacing
with a host computer through the AXB-EM232 or directly to the AXB-CAM.
The system software assumes a standard configuration using videoconference-style
lenses, including Fujinon BMD and Canon KTSA format lenses, which require no
modification. If the system includes optional components and software—such as
CCTV-type lenses (direct DC drive and reference POTs), RS-232-controlled lenses, or
video switching—refer to the documentation that came with those components and
software applications or contact their manufacturers for additional information.

Note
A separate power supply is only
required in applications controlling
more than one camera station, as in
Figure 1. For applications using only
one camera station, the power supplied
from the AXP-DTC via the +12 V wire
in the AXlink is sufficient to power the
three camera station components, the
AXB-EM232, AXB-CAM, and
CAM-1000.
The AXP-DTC provides a traditional joystick and illuminated pushbutton mode of
control for camera positioning and lens control. Two dual-axis, proportional-speed
joysticks with oversized handles furnish comfortable, precision pan, tilt, zoom, and
focus control. Adjustable iris control with automatic and manual modes is available
as well. You can select up to six camera stations as well as store and recall eight
preset shots for each of three modes per camera station. The three mode buttons can
provide a variety of features through AMX custom programming, including
selection of optional banks of cameras or activation of routing commands to a video
switcher.
The AXB-CAM is an AXlink device that can control a wide variety of motorized
pan/tilt heads and camera lenses that use low-current (5 VDC to 12 VDC) and/or
high-current (-24 VDC to 24 VDC) control voltages. The AXB-CAM uses 8-bit (256

steps) and 10-bit (65,535 steps) precision-control processing, and is equipped with a
lithium battery that protects stored memory.
The CAM-1000 is a motorized pan/tilt head designed for precision, preset camera
positioning. The motor drives are optimized for 0 to 12 VDC control and accept 0 to
24 VDC as well for universal system compatibility. Precision POTs provide pan and
tilt position sensing for presets.
