Quick answers about the DCNM-WD, and how it compares.
DCNM-WD or DCNM-WDE?
| DCNM-WD | DCNM-WDE | |
|---|---|---|
| Screen | None | 4.3-inch touch: custom logo, speaker list, request list, user interface languages in original characters |
| NFC identification | No | Yes, with DCNM-LSID |
| Voting at the seat | No | Yes, with DCNM-LSVT |
| Dual use | With DCNM-LSDU | With DCNM-LSDU |
| Battery life | Over 24 h | Over 20 h |
| Weight with battery | 1051 g | 1131 g |
Both have a microphone socket, a built-in loudspeaker and two headphone sockets, and can be set as a participant, dual use or chairperson device. Choose the WDE where participants vote or log in with NFC cards.
Can two participants share one DCNM-WD?
Yes, with a DCNM-LSDU dual use license for the device. Each participant has their own microphone request button, and their name shows correctly in the speaker list. One can speak while the other waits in the request list.
How long does the battery last?
Over 24 hours (20% speaking, 80% listening) on a fully charged DCNM-WLIION2. The pack swaps in seconds, and the access point web interface shows battery status per seat. A DCNM-WCH05 charges five packs at once in about three hours.
Can participants listen on headphones?
Yes. Each device has two 3.5 mm stereo headphone sockets, left and right, each with its own volume control, so the speaker is clear even in a noisy room. The built-in loudspeaker and microphone can be on at the same time for a face-to-face feel; a built-in feedback suppressor prevents howling.
Is a microphone included?
No. DICENTIS discussion devices come without a microphone, so you choose one for each seat: the DCNM-HDMIC high directive microphone, or the DCNM-MICS (short) or DCNM-MICL (long) stem microphone. All three click into the same socket.
The screw-lock DCNM-MICSLS / DCNM-MICSLL are for flush seats and do not fit these devices.
What do the red and green lights mean?
The light on the microphone head shows your status: red means the microphone is on and you are live; green means your request to speak has been accepted and you are next.
What do I need for a DICENTIS Wireless system?
DICENTIS Wireless runs stand-alone, with no central control unit. You need:
- One DCNM-WAP access point: controls up to 120 DICENTIS devices. You set up and run the meeting from its web browser interface on a tablet or laptop.
- A wireless device per seat: DCNM-WD for discussion, or DCNM-WDE with a touch screen and NFC reader.
- A microphone per device: DCNM-HDMIC, DCNM-MICS or DCNM-MICL.
- A battery pack per device: DCNM-WLIION2, charged five at a time in the DCNM-WCH05.
- Optional licenses for dual use, identification, voting and camera control.
Typical coverage is 30 x 30 m per access point. A second WAP can be set up as a secondary access point for redundancy and meeting continuity.
Which licenses does DICENTIS Wireless use?
Discussion works without a license. These functions are added with licenses, activated in the DCNM-WAP web browser interface:
| Function | License | How many |
|---|---|---|
| Dual use: two participants share one device | DCNM-LSDU | One per WD or WDE |
| Identification by NFC card | DCNM-LSID | One per WDE, two in dual use |
| Voting at the seat | DCNM-LSVT (ask us) | One per WDE, two in dual use |
| Camera prepositions per seat | DCNM-LCC (ask us) | One per WAP |
Identification and voting work on the DCNM-WDE only. Each license is delivered as an activation code by e-mail.
Will DICENTIS Wireless interfere with our Wi-Fi?
No. It uses standard Wi-Fi (IEEE 802.11n) in the license-free 2.4 GHz and 5 GHz bands and is designed to co-exist with other Wi-Fi networks, mobile phones and access points nearby.
- Automatic channel switching: the access point moves to another channel seamlessly.
- Range test: checks that every device is in range on any channel the system may use.
- Packet loss concealment: masks lost packets in the audio.
- WPA2 encryption: protects against eavesdropping and unauthorized access.
No extra Wi-Fi router is needed: the tablet used for control connects to the DCNM-WAP directly.
