System Description
APPLICATIONS
The DynamicX2Talk system is a professional TFT display with DynamicTalk and
an electrical lift system for installation into a horizontal furniture surface. The
DynamicTalk system is a universal motorized microphone lift system remotely
controllable through RS422 or GPI with Dynamic LED Ring for “Ready to Talk”
and “Talk” indicators.
In the starting position (retracted) the screen's monitor is placed inside the
table leaving the desk free of any obtrusive element. When in this position, the
power will automatically be disconnected in order to save energy and preserve
panel life. By pressing the rear button located on the table cover plate, the TFT
panel raises up into the working position (raised and tilted). The TFT power is
then restored.
This TFT-LCD product range is specially designed for desk integration in:
Conference rooms Meeting rooms Board rooms
Auditoriums Information desks Training rooms

MICROPHONE LENGTH SETTING PROCEDURE
DynamicTalk is designed to work with microphones of different lengths. Two
signs to identify an incorrect setup of the microphone length are:
- The microphone do not goes down completely.
- The microphone goes down too slowly and gets stuck inside.
The microphone length can be adjusted using the Monitor Configurator
Tool, but there is also a quick procedure that doesn’t require the use of a
PC or cable:
1. Disconnect the Power connector
2. Set switch 5 to ON position
3. Set the length of the microphone in the rotatory switch,
in cm. For instance, if the microphone is 40cm, set the
rotatory switch as: tens=4, unit=0
4. Connect to Power. There will be a 5 beep sound
5. Disconnect Power
6. Set switch 5 to OFF position
7. Set the AHnet address in the rotatory switch, the default
setting is address 01 (tens=0, units=1).
8. Connect the Power connector
