SYSTEM DESCRIPTION
General
Arthur Holm’s DB2Share is a motorised retractable communication
solution that creates minimum impact on the furniture’s design. It is
easy to integrate, intuitive to use (one simple operation sensor located
on the top of the monitor) and almost invisible (no cover plate, neatly
streamlined into the furniture) when not in operation. This solution
provides full control to view and share documents and videos with a
motorised retractable HDMI cable that raises as an extension of the slick
design of the monitor.
By touching directly on the monitor, users can select the HDMI input
and share it. Monitors are equipped with 2 HDMI-HDCP compliant inputs
and 1 output, allowing the daisy chain of a maximum of 20 devices. An
Interactive Setup Display allowing the control, setup and diagnose of
the monitors. Monitors provide RS-422 I/O allowing the remote control of
movements, speeds, safety settings, brightness, contrast and backlight.
The monitors are equipped with AH-AMMC: an auto mechanical
calibration movement system.
The use of the Arthur Holm’s ERT will enable the address configuration
of all the monitors installed in a table by simply pressing a button. The
AHlink Android and iOS app allows getting the monitor’s serial number
without removing the unit from the table and allows access to the setup
and control menus.
Highlights
• The smallest impact on the table surface
• Includes a retractable HDMI cable and on glass touch buttons
• Front double sided anti-reective 2 sides coating 2 mm glass
• Energy saving, low consumption video controller
• AH-AMMC Auto mechanical movement calibration
• Wireless connectivity for setup and control
• No cover plate required
• 20 mm max thickness

GENERAL DYNAMICSHARE INFORMATION
DynamicShare is an equivalent to multiple HDMI selectors connected to
multiple cascade HDMI distribution amplifiers in a daisy chain topology,
allowing the user to display local sources privately, without affecting the
other users in the loop and allowing to share a local signal to the rest of
the monitors.
DynamicShare HDMI connection:
The HDMI loop daisy chain connection allows to share a local signal
with all monitors on a particular loop. The image that is displayed on
the screen is controlled by two buttons on the upper cover plate of the
monitors. On the DB2 monitors, two capacitive buttons are placed on
the screen’s glass.
Each monitor has different HDMI input signals. Depending on the model,
the monitor could have up to 3 HDMI local inputs. HDMI1 is located
below the monitor. Depending on the model, the monitor has 2 more
HDMI inputs located below the monitor on located on the monitor’s
cove plate. There is the option to add a fixed HDMI connector or a
retractable HDMI cable on the cover plate. A loop HDMI input signal
is used to receive the active share signal connecting the monitors in a
daisy-chain loop topology. The loop HDMI output signal is used to send the
active share signal to the next monitor or to send the local signal to the
rest of the monitors by using the share HDMI loop.
VIEW push button: This button selects the input signal to be shown on the screen
(local HDMI input or loop shared input). Note that by pressing the view button, the
system will only select one local active input. To activate the PRIVATE mode, press
the button for 5 seconds (the green LED will be on). In private mode, the monitor will
always display the local input, even if another monitor activates the share function.
SHARE push button: Press this button to share the local signal. The red LED indicates
that the monitor is sending the local image to the HDMI loop and all the monitors will
display this input. By pressing this button again, the share will be interrupted, and the
red LED will turn o.
