Key Digital KeyCode Open API enables third-party network control of external hardware
— The KeyCode Open API architecture native
to Key Digital® controllers and control-equipped 4K AV over IP
encoders/decoders offers an affordable and simple means of extending digital AV
network control to non-networked devices through translation of networked text
streams to RS-232 or IR commands —
VERNON, NY, August 1, 2022 – Digital control, processing and signal
distribution networks have revolutionized the AV systems industry for the
better. Yet, many AV networking systems do not have the ability to control
disparate external hardware components that lack network interface
capabilities. “There is a simple, affordable solution to extending the control
capabilities of such systems,” says Jonathon Ferry, VP of product education and
experience at Key Digital®, an award-winning developer and manufacturer of
leading-edge digital video processing, video signal distribution, collaboration
and communications solutions.
Digital offers a standalone controller, and video encoders and decoders with
built-in controller functionality,” Ferry continues. “By means of our KeyCode Open
API architecture, our hardware can control any device that accepts RS-232 or IR
commands, such as video displays, projectors, motorized screens, cameras,
cable/satellite TV boxes, lighting controllers, music players and thermostats, as
well as our own hardware. The proprietary networked system simply sends a
device command to a flexibly designated port as an ASCII text string via
TCP/IP.” Key Digital hardware sharing the TCP/IP network can be configured to
monitor a defined port, intercept and translate the text stream and deliver it
to the target device via IR or RS-232. The bi-directional ports can also
receive data, such as a command acknowledgement or status report, and return it
to the source network.
control capability is native to Key Digital’s KD-CX800 Controller and 4K AV
over IP system encoders and decoders, all PoE-ready for ease of installation.
The KD-CX800 Controller is a dedicated control-over-TCP/IP device with dual
TCP/IP ports and three bi-directional control ports – one supporting IR out
(emitter) and IR in (sensor or hardwire) and two multi-function ports
supporting IR, RS-232, voltage trigger or voltage sensor operation. The
flexible KD-CX800 can serve as a control gateway for Key Digital 4K AV Over IP
systems, “enabling more third-party control options than other HD over IP
systems,” says Ferry. What’s more, he adds, “Through support of generic RS-232
and IR command strings delivered via TCP/IP, “the KeyCode Open API brings
cost-effective bi-directional control expansion to advanced third-party control
systems and adds a reliable hardware interface to network-based control apps.”
As a CAT-connected network device, the KD-CX800 by default can extend control
signals up to 400ft / 121m.
the robust API allows for bi-directional communication with third-party
networked hardware implementing the Compass Control® Pro fully integrated
iOS-based control system (developed by Key Digital and supported in hardware
from more than 60 Compass Alliance partner brands) and also allows direct
TCP/IP device control from iOS controllers with no ports used.
CX800 Controller functionality is also available in Key Digital’s family of 4K
UHD AV over IP HDMI-to-IP encoders and decoders. The KD-822ENC/DEC is equipped
with a single TCP/IP port and one bi-directional IR port and one multi-function
port. The KD-922ENC/DEC devices have the full CX800 feature set while adding
audio de-embedding with Lip Sync control, audio pre-amp and video wall
processing. The advanced-featured KD-1022ENC/DEC devices add independent video,
audio and USB switching, audio control, video mosaic wall processing and
KVM/USB extension and routing to the feature set. “These devices let users
create matrixed 4K AV over AV systems of any size and level of sophistication
with the benefit of third-party control of the system and external devices via
the KeyCode Open API,” says Ferry.
networks can expand into video with Key Digital 4K AV over IP hardware and
retain centralized control,” he elaborates. “Or, where a networked system
simply needs to add control of a few external devices, one of our
control-capable devices employing the KeyCode Open API provides an elegant
solution that’s very simply implemented.”
