KD-BYOD4KHub Setup Guide — Wireless Presentation & Conferencing Gateway

Quick answer: Connect the Main HDMI OUT to a display, power the unit (or use PoE on LAN 1), join KD-BYOD4KHUB-XXXX (default 12345678), browse to 192.168.43.1, admin password admin, choose your network mode. Up to 5 presenters can share at once; the hub forwards wireless USB camera/mic/audio to the host PC.

What makes the Hub different from the KD-BYOD4K

The original KD-BYOD4K is presentation-only. The Hub adds conferencing (BYOM): it captures the room's USB camera, microphone, and speakers and routes them — wired or wirelessly — to a presenter's computer for Zoom, Teams, Meet, or any UVC/UAC software. It also adds dual HDMI outputs, a wired HDMI input, Miracast, RS-232/CEC display control, and digital signage mode.

Key capabilities

• BYOD presentation: KDPlay+ app (Windows/Mac), AirPlay (iOS/Mac), Chromecast (Chrome), native Miracast (Windows/Android).
• BYOM conferencing: forwards USB camera, mic, and speakers (UVC/UAC; 8/16/24-bit USB audio) to the host computer.
• Up to 5 simultaneous presenters; up to 16 connected devices.
• Dual HDMI outputs (Main + Sub): Mirrored, Full-Screen + Multi-View, or Multi-View + Full-Screen.
• Wired HDMI input (up to 1080p 50/60) for a room PC or camera.
• Annotation/whiteboard, output capture/preview for remote participants, extended-monitor support.
• Digital signage mode, customizable home screen.

WiFi Direct vs WiFi Client vs LAN Connection

• WiFi Direct (default): clients connect to the Hub's own access point. Fastest setup.
• WiFi Client: the Hub joins your existing WiFi router with no permanent network cable.
• LAN Connection: the Hub is wired into your network; clients reach it over your WiFi.

Setup

1. Cabling

• WiFi Direct: Main HDMI OUT → display; connect power (or PoE on LAN 1); optional LAN to an internet-enabled network for client internet.
• WiFi Client: Main HDMI OUT → display; power; temporarily connect a LAN cable for initial setup (removed later).
• LAN Connection: HDMI → display; LAN cable from router/switch (LAN 1 supports PoE); optional second network.

LAN port facts: LAN 1 = 1 Gbps + PoE (powers the Hub). LAN 2 = 100 Mbps, no PoE.

2. Configure

1. Join KD-BYOD4KHUB-XXXX (default 12345678), browse to 192.168.43.1, ADMIN ACCESS → admin.
2. WiFi Direct: Network → Wireless → set SSID + password (letters/numbers only) → Save.
3. WiFi Client: with a LAN cable attached, confirm the Hub's IP on the home screen, join the same LAN, browse to that IP → Network Mode → WiFi Client → Wireless Scanner → pick WiFi → password → Connect → Save, then remove the cable.
4. LAN Connection: Network Mode → LAN Connection → reconnect at the shown IP → Wireless tab → SSID/password → 2.4/5 GHz → Wireless Scanner → connect → optional static IP via Ethernet LAN.

3. Cast

• Driver note: Windows/Mac need the WMMeeting driver (installs on first KDPlay+ use; may need admin rights). On macOS Sequoia, enable KDPlayPlus under Login Items & Extensions → Camera Extensions.
• KDPlay Flash (preferred): insert the included KD-BYODFD dual-head dongle → auto-joins and connects → Start Mirroring.
• iOS: Control Center → Screen Mirroring → choose the Hub.
• Android: Settings → Connected Devices → Smart View → pick the Hub (Miracast recommended for audio).
• Chrome OS: Chrome ⋮ → Cast → choose source → select the Hub.

4. Conference (BYOM)

1. In the KDPlay+ app, open Settings → set Wireless Device as the USB host.
2. Connected camera/audio show as dark-grey buttons (also on the home screen).
3. In your conferencing app choose "Virtual Meeting Camera" and "Virtual Meeting Audio" — buttons turn green when in use.
4. Use the Preview Monitor to screenshare the room's casted content to remote participants.

To send the room's USB devices to a wired host instead, connect it to the USB Host port — KDPlay+ isn't required.
