Key Digital has released a firmware update for its KD-Pro4x1X-2 HDMI switcher, adding IP to RS-232 command forwarding to its capabilities. Introduced last month, Key Digital says the firmware update enables the second-generation 4×1 UHD/4K/18G HDMI switcher to function as part of a presentation system similar to Key Digital Unified Communication and Control products.

By connecting the KD-CamUSB PTZ camera or the KD-Amp220 audio pre-amp/amplifier to the KD-Pro4x1X-2 via each device’s RS-232 ports and enabling control of the devices from the free Key Digital Management Software Pro (KDMS Pro) app for Windows or a new web UI, users can control the camera and amp from the free KD App for iOS, the web UI, Key Digital’s Compass Control Pro integrated iOS control system or with TCP/IP commands from other networked devices.

Current KD-Pro4x1X-2 owners can download and install the firmware update via the KDMS Pro app.
