Overview

The Extron SY ISTP/100 is a purpose-built install cable that bridges VGA sources to BNC-input equipment such as matrix switchers, distribution amplifiers, and professional monitors. One end carries a standard 15-pin HD male connector, while the opposite end breaks out into five individually shielded BNC male connectors for Red, Green, Blue, Horizontal Sync, and Vertical Sync. The MHR-5P cable construction uses mini high-resolution coaxial conductors bundled together, providing consistent impedance and low signal loss across the 100-foot run length.

What sets this cable apart from generic VGA-to-BNC adapters is its NEC CMP plenum rating. In commercial buildings, any cable routed through air-handling spaces must meet strict fire safety standards — the SY ISTP/100's low-smoke, flame-retardant jacket satisfies that requirement, keeping your installation compliant with local building codes and inspection requirements. For AV integrators working in offices, conference centers, houses of worship, or education facilities, this cable eliminates the need to run standard cables inside separate plenum-rated conduit, simplifying installation and reducing labor costs.

Pros & Cons

👍 Pros

  • Plenum-rated jacket meets NEC CMP fire code requirements for in-ceiling and in-wall installation.
  • Five individual BNC connectors provide discrete RGBHV signal paths for cleaner high-resolution video.
  • 100-foot length suits most commercial AV runs without requiring extenders or repeaters.
  • Extron-branded build quality with connectors designed to match Extron switching and distribution equipment.
  • Pre-terminated ends eliminate the need for on-site crimping or soldering during installation.

👎 Cons

  • VGA/RGBHV is an analog standard with no support for HDMI, DisplayPort, or digital audio signals.
  • 100-foot fixed length cannot be shortened without re-terminating, and may be excessive for smaller rooms.
  • Five individual BNC connectors require more patch panel space and labeling effort than a single HDMI or HDBaseT connection.
  • Premium plenum-rated pricing is unnecessary if your installation does not require in-plenum routing.

Frequently Asked Questions

The Extron SY ISTP/100 carries a NEC CMP plenum rating, meaning its jacket produces low smoke and flame spread when exposed to heat. This allows it to be legally installed in plenum airspaces — the areas above drop ceilings and below raised floors used for HVAC airflow — where standard PVC-jacketed cables are not permitted by building codes.
The MHR-5P cable type is designed to carry high-resolution RGBHV analog video signals. It supports resolutions typically up to 1920x1200 at distances appropriate for the cable length, making it suitable for most professional AV presentation and signage applications.
One end terminates in a 15-pin HD (VGA) male connector, and the other end splits into five individual BNC male connectors, carrying the Red, Green, Blue, Horizontal Sync, and Vertical Sync signals separately.
This is an install-grade cable intended for permanent runs through walls, ceilings, and conduit. Its plenum rating and build quality are engineered for fixed infrastructure, not portable setups.
The "/100" in the model designation indicates a 100-foot cable length.
