KD-PS42
Key Digital ® KD-PS42 is a 4K/18G KD-App Ready Presentation Switcher kit
with CEC Manager ™, auto switching, and audio de-embedding creating a user-
friendly, simplified presentation system. KDPS42 features three HDMI and one
HDBaseT input which integrates natively with HDMI + Display Port wall plate,
KD-X2x1WDTx (sold separately). Mirrored HDMI and HDBaseT outputs enable
audience + presenter views and the HDBaseT output marries in with the included
KD-X40MRx for integrating monitors or projectors up to 40m / 131ft away when
the selected source is outputting 4K/UHD (up to 70m / 230ft at 1080p).
Designed for professional audio video installations in conference rooms, board
rooms, classrooms, lecture halls, auditoriums, and more, KD-PS42 enables
multiple video sources to be displayed on up to two connected displays while
analog (balanced/unbalanced) and digital (PCM) audio de-embed ports feed audio
of the selected source into an amplifier, DSP, or sound bar. Integrating KD-
PS42 with KD-AMP220 will enable an app-ready all-in-one solution for control
of video switching with sound and speech enforcement. Key Digital CEC Manager
™ enables basic controls of the connected displays for a simplistic all-in-one
integration system. KD-PS42 presentation switcher supports all SD, HD, VESA,
and Ultra HD/4K video standards with HDR header information included in a
variety of 4K EDID handshakes. In addition to IR,
RS-232, and TCP/IP control, KD-PS42 can also be controlled via trigger voltage
and features status monitoring LEDs.

Your unit is now ready to control from the KDMS Control Panel, KD-App, or by the professional control system.
CONTROL
Option 1: Control via Remote Control
http://www.keydigital.com/items.asp?ItemCode=KDAPP&Company=KEY
- Display Control via CEC Manager™ buttons at the top left and top right
- Input selection via buttons at the bottom
- Note: Blue buttons at the center are for KD-CAM USB control. KD-CAM USB does not natively integrate with KD-PS42.
Option 2: Control via KD-App, Key Digital® Management Software™ Pro
KD-PS42 is controllable by Key Digital’s user-friendly iOS App (downloadable in the App Store) or Key Digital® Management Software™ Pro (downloadable here).
- Connect and Configure your KD-PS42 as described in this Connect & Configure sections
- Download and open KD-App and/or KDMS™ Pro
- Ensure the iOS device and/or PC computer are on the same network with KD-PS42
- Perform a network scan in the KD-App and/or KDMS™ Pro
- Select and control the selected KD-PS42
- To enter KDMS™ Pro end-user mode, key CTRL + ALT + N after selecting the KD-PS42
Option 3: Control via the professional control system
KD-PS42 allows control over the serial interface for bi-directional
communication.
-
For RS-232 control use pins 4, 5, and 6 of the Main Control port
-
For TCP/IP control, the default static IP address is 192.168.1.239, with port 23
-
For the past 10 years, most Key Digital switches have supported a standard HDMI switching command. KD-PS42 is also controllable by this command, so if you have previously integrated Key Digital matrixes by third-party control systems you may have success using the same driver/module.
