BOSCH DCNM-D Discussion device
- Removable Battery Pack, easy to change and charge
- Configurable as a participant, dual-use or chairperson Wireless Device by use of web browser interface
- Functionality can be expanded with software modules without the need for hardware modification
The elegantly designed Wireless Device (DCNM‑WD) of
the DICENTIS Wireless Conference System enables
participants to speak, register a request-to-speak, and
listen to the speaker during a meeting.
The device can be easily configured as a single-use,
dual-use or chairperson Wireless Device via the web
browser interface of the Wireless Access Point
(DCNM‑WAP).
Functions
General
• The Wireless Devices connect to the DCNM‑WAP.
• Single‑use, dual-use or chairperson can be configured
via the web browser interface.
• Audio mute button.
• Operates in the 2.4 GHz and 5 GHz (UNII1, 2
(extended) and 3) (license free) band.
Speech intelligibility
• Maximum speech intelligibility is guaranteed at all
times.
• The Wireless Devices connects to the DCNM‑WAP.
• The Wireless Devices produce crystal‑clear sound due
to a very high signal‑to‑noise ratio and smart
frequency selection.
• The loudspeaker and microphone can be active at the
same time for a face‑to‑face meeting experience. To
prevent acoustic feedback, a feedback suppressor is
built‑in.
Zero Interference
• Based on standard WiFi.
• Seamless automatic frequency channel switching.
• WiFi coverage area range test.
• Packet Loss Concealment.
Security
• The DICENTIS Wireless Conference System and
Wireless Devices have secure connectivity using
WPA2 to prevent eavesdropping and unauthorized
access.
• Encryption ensures that information within the
system remains confidential.
Microphones
• A socket is provided to connect the pluggable
microphone (DCNM‑HDMIC, DCNM‑MICS or
DCNM‑MICL, all to be ordered separately).
Headphones and loudspeakers
• The Wireless Devices accommodate two headphone
connections and controls (on the left and right-hand
side), so the speaker can be heard clearly even with
excessive background noise.
Battery maintenance
• Rechargeable Battery Pack (DCNM‑WLIION).
• The lithium‑ion Battery Pack can be removed and
replaced in a matter of seconds, providing maximum
flexibility in recharge scheduling.
• Smart battery management via web browser interface
control (battery status and usage counting time).
Controls and Indicators
• On top side:
– Microphone with a red or green indicator:
- Red indicates microphone is active.
- Green indicates request-to-speak accepted.
– LED indicators on device showing:
- Microphone on state – Red.
- Possible‑to‑speak – White.
- Priority – White (Chairperson only).
- Request‑to‑speak – Green.
• On the left and right hand side
– Headphone rotary volume controls.
• On rear side:
– Yellow out‑of‑range of Wireless Access Point LED
indicator.
– Red battery low LED indicator.
• Under base side:
– Recessed, so called ‘De‑init,’ switch to
disconnect the connected Wireless Device with
the Wireless Access Point (DCNM‑WAP).
Interconnections
• Socket for pluggable microphone.
• Two 3.5 mm (0.14 in) headphone sockets stereo jack type.
