The LNK-MHD-1V Series is a compact, high-performance Mini-type HD-SDI to Fiber Converter
with Tally & Reverse RS485, specifically engineered to integrate multi-signal transmission into a
space-saving mini form factor—ideal for scenarios where installation space is limited, such as
portable broadcast setups, compact control cabinets, on-site surveillance deployments, or small-
scale live event production environments. As a Mini-type HD-SDI to Fiber Converter with Tally &
Reverse RS485, it combines reliable HD-SDI video transmission with essential auxiliary signals,
catering to professional fields that demand both miniaturization and multi-functional integration for
efficient, space-efficient workflow operations.
This converter supports synchronized transmission of 1-channel HD-SDI video signals (with
embedded audio for seamless audio-video synchronization, ensuring no latency or desynchronization
between sound and image), 1-channel Tally signal, and 1-channel Reverse RS485 data signals via a
single fiber optical cable—eliminating the need for multiple independent cables, simplifying on-site
infrastructure deployment, and reducing overall installation and maintenance costs. It is equipped with
a local HD-SDI loop output, allowing users to monitor the source video signal in real time at the transmitter
end; this real-time monitoring function ensures signal integrity before long-distance transmission, facilitates
quick troubleshooting in professional workflows (such as identifying signal distortion or loss early), and avoids
potential disruptions to critical applications like live broadcasts or high-definition surveillance.
The Mini-type HD-SDI to Fiber Converter with Tally & Reverse RS485 is supplied as a complete functional
set, including one dedicated transmitter unit and one matching receiver unit, which work together to form a
stable, full-duplex transmission link optimized for HD-SDI signal transmission. It delivers broadcast-grade
HD video quality, meeting the strict standards of professional AV applications—whether used in live event
streaming, studio monitoring, educational video transmission, or high-definition security surveillance systems.
Meanwhile, the converter maintains strong compatibility with mainstream HD-SDI devices, ensuring seamless
integration with existing infrastructure without the need for additional adapters or configuration.
The integrated 1-channel Tally signal function is critical for professional broadcast and live production scenarios,
enabling real-time status indication of video sources (such as “on-air” active status or “preview” standby status)
to help production teams coordinate smoothly and avoid operational errors. The 1-channel Reverse RS485
function supports bidirectional serial data communication, allowing remote control of connected devices
like PTZ cameras, studio lighting controllers, or industrial monitoring equipment from the receiver end
—enhancing operational flexibility and reducing the need for on-site manual adjustments. With its compact
mini design, stable multi-signal transmission, and broadcast-grade video performance, this converter
effectively resists electromagnetic interference (EMI) and signal attenuation over long fiber distances,
ensuring consistent HD video quality, reliable Tally status feedback, and smooth Reverse RS485 control
—making it a practical, cost-effective solution for modern professional HD-SDI video transmission needs.
