Professional broadcast equipment does not always use the same type of SDI connector. Traditional cameras, production switchers, monitors, and video converters commonly use standard BNC connections. However, high-density broadcast equipment may use smaller HD-BNC or DIN 1.0/2.3 connectors to accommodate more video connections within limited panel space.

When connecting these different interfaces, selecting the correct cable assembly is essential.

A standard BNC connector cannot be plugged directly into a DIN 1.0/2.3 port. Likewise, HD-BNC and DIN 1.0/2.3 connectors are physically different and cannot be connected directly to each other.

Professional 75-ohm cable assemblies are available with different connector types installed on opposite ends.

In this guide, we'll explain DIN 1.0/2.3 SDI connectors, compare them with standard BNC and HD-BNC connections, and show how to select compatible cables for professional 6G-SDI and 12G-SDI video systems.

WHAT IS A DIN 1.0/2.3 CONNECTOR?

DIN 1.0/2.3 is a compact coaxial connector interface used in telecommunications, professional video, and broadcast equipment.

Its small physical size makes it useful when equipment manufacturers need to install numerous coaxial connections in a limited amount of space.

Professional broadcast-video applications commonly use 75-ohm DIN 1.0/2.3 connectors. However, DIN 1.0/2.3 connectors are also manufactured in other impedance configurations, including 50 ohms.

For professional SDI video, select a connector assembly designed for the required 75-ohm signal path.

DIN 1.0/2.3 connectors should not be confused with traditional multi-pin DIN audio connectors or other similarly named connector families.

DIN 1.0/2.3 VS. BNC VS. HD-BNC

Standard BNC, HD-BNC, and DIN 1.0/2.3 connectors can all be used in professional broadcast-video systems when the appropriate 75-ohm versions and performance ratings are selected.

However, their physical interfaces are different.

The most important consideration is matching the connector installed on the cable to the actual connector interface on the equipment.

Do not select a cable solely because both devices support 12G-SDI. The physical connector type must also match.

WHEN SHOULD YOU USE A BNC TO DIN 1.0/2.3 CABLE?

A BNC-to-DIN 1.0/2.3 cable is used when one piece of equipment has a standard BNC connection and the other has a DIN 1.0/2.3 connection.

This configuration may be useful when connecting traditional broadcast equipment to high-density video routers, monitors, converters, or other compatible devices.

A purpose-built BNC-to-DIN cable provides the required connector types on one assembly without requiring a separate rigid adapter.

AV-Cables manufactures this configuration using genuine Belden 4855R Mini RG59 coaxial cable with precision 75-ohm connectors.

WHEN SHOULD YOU USE A DIN TO DIN SDI CABLE?

A DIN-to-DIN cable is designed for compatible equipment with DIN 1.0/2.3 connections at both ends of the signal path.

For example, a high-density video router may need to connect to another compatible device using the same compact interface.

Instead of converting to standard BNC and then converting back to DIN, a direct DIN-to-DIN cable can provide a simpler connection.

Advantages include:

• Matching connector types at both ends
• No separate conversion adapters required
• Compact cable routing
• Fewer individual connection components
• Custom cable-length options
• Professional 75-ohm construction

Confirm that the equipment ports are compatible with the exact DIN 1.0/2.3 connector design used on the cable.

WHAT ABOUT HD-BNC TO DIN 1.0/2.3?

Some professional video systems use multiple types of compact coaxial connectors.

One device may have an HD-BNC interface while another uses DIN 1.0/2.3.

Although both connector types are compact, they are not physically interchangeable.

An HD-BNC-to-DIN cable provides the correct connector on each end.

This configuration can be useful in high-density broadcast racks, mobile production trucks, fly packs, and professional video-routing systems.

AV-Cables offers professional HD-BNC cable assemblies for compatible broadcast equipment.

HOW TO CHOOSE THE CORRECT SDI CONNECTOR CONFIGURATION

Before ordering a cable, identify the physical connector type on both pieces of equipment.

This table assumes compatible female equipment ports and cable assemblies with corresponding male connectors.

Always confirm connector gender, impedance, and mating compatibility before ordering.

WHY BELDEN 4855R MINI RG59 WORKS WELL FOR HIGH-DENSITY SDI CONNECTIONS

When multiple SDI connections are installed behind a broadcast router or production rack, cable size becomes important.

Large coaxial cables can occupy substantial space and make equipment connections more difficult to organize.

Belden 4855R is a compact professional 75-ohm Mini RG59 cable designed for compatible single-link 12G-SDI applications.

Its nominal outside diameter is approximately 4.04 mm.

For high-density equipment connections, the smaller cable diameter can simplify routing compared with full-size RG59 or RG6 coaxial constructions.

However, larger coaxial cables may be preferable for longer signal paths where lower attenuation is required.

DOES A DIN 1.0/2.3 CONNECTOR SUPPORT 12G-SDI?

DIN 1.0/2.3 is a connector family, not an automatic guarantee of 12G-SDI compatibility.

Professional 12G-SDI applications require cable assemblies designed to support the required high-frequency signal performance.

The completed signal path must account for:

• Connector impedance
• Connector frequency performance
• Coaxial cable construction
• Connector termination quality
• Total cable length
• Additional adapters or patch connections
• Connected equipment capabilities

A DIN 1.0/2.3 connector designed for a lower-frequency application should not automatically be considered suitable for 12G-SDI.

Likewise, installing a 12G-rated connector on an unsuitable coaxial cable does not make the complete assembly 12G-capable.

DIRECT CABLE ASSEMBLY VS. SEPARATE CONNECTOR ADAPTER

When connecting different SDI interfaces, installers sometimes use a separate adapter to change connector types.

For example, a standard BNC cable might be connected to a DIN 1.0/2.3 device using a suitable BNC-to-DIN adapter.

This can be useful when adapting an existing installation.

Fewer Separate Components

A direct cable assembly eliminates the need to manage an additional adapter as a separate part.

Reduced Mechanical Complexity

A short flexible cable can help avoid placing the weight of a longer cable directly on a rigid adapter attached to a compact equipment port.

Custom Cable Lengths

A purpose-built assembly can be manufactured to the length needed for the equipment layout.

Simpler Cable Identification

Matching jacket colors, labeling, and connector configurations can help technicians identify the correct signal path.

A properly specified adapter may still be appropriate for certain applications. All components must support the required SDI signal format and electrical performance.

INSTALLATION TIPS FOR COMPACT SDI CONNECTORS

COMMON DIN 1.0/2.3 SDI CONNECTION PROBLEMS

Problem 1: The Connector Does Not Fit

The equipment may use HD-BNC instead of DIN 1.0/2.3, or the selected connector may have an incompatible mating configuration.

Solution: Verify the exact connector interface in the equipment documentation.

Problem 2: The Cable Works at HD-SDI but Not 12G-SDI

The cable assembly or another component in the signal path may not provide sufficient performance for the higher data rate.

Solution: Verify cable and connector ratings, total length, and connected equipment specifications.

Problem 3: Video Drops Out When the Cable Moves

A damaged connector, compromised termination, or mechanical stress may be affecting the connection.

Solution: Inspect the assembly, support the cable properly, and test or replace the suspect cable.

Problem 4: Signal Problems Appear After Adding an Adapter

An additional adapter introduces another connection interface into the signal path.

Solution: Confirm that the adapter supports the required impedance and signal format. Consider a purpose-built cable assembly with the correct connectors.

THE BOTTOM LINE

DIN 1.0/2.3 connectors provide a compact option for professional broadcast equipment where panel space is limited.

However, DIN 1.0/2.3, HD-BNC, and standard BNC connectors are not physically interchangeable.

When connecting different interfaces, select a cable assembly with the correct connector type on each end.

For 12G-SDI applications, the entire cable assembly must also support the required electrical performance.

Purpose-built BNC-to-DIN, DIN-to-DIN, and HD-BNC-to-DIN cable assemblies can simplify installation and reduce the need for separate connector adapters.
