Black Box AVX-DVI-TP-100M XR DVI-D Extender with Audio and RS-232

Overview

The Black Box AVX-DVI-TP-100M is a DVI-D signal extender designed to push digital video, audio, and RS-232 serial control well beyond the reach of a standard DVI cable run. If you are wiring a boardroom, command center, digital signage deployment, or any environment where the source and display must be separated by a meaningful distance, the AVX-DVI-TP-100M handles all three signal types — video, audio, and serial — over a single twisted-pair infrastructure rather than requiring parallel cable runs for each.

The inclusion of RS-232 pass-through is the detail that separates this unit from basic video-only extenders. Serial control is essential when the display, projector, or controlled device needs to receive power-on commands, input-switching instructions, or status polling from a control system at the source end — without a separate control cable pulled to the display location.

Key Features

• DVI-D Digital Video Extension: Transmits an uncompressed digital DVI-D signal to the remote display, preserving the signal quality you would expect from a direct connection — no analog conversion artifacts, no compression-related latency.
• Integrated Audio Extension: Audio travels with the video over the same infrastructure, eliminating the need to run a separate analog audio cable to the display or speaker system at the remote end.
• RS-232 Serial Control Pass-Through: The AVX-DVI-TP-100M (often searched as AVX DVI TP 100M) extends RS-232 alongside video and audio, letting a control processor at the source location operate a display or projector at the far end without an additional control cable run.
• Twisted-Pair Transmission: Uses structured Cat-type cabling rather than proprietary coax or fiber, so installations can leverage existing building infrastructure and standard termination tools.
• Compact Black Chassis: The transmitter and receiver units are finished in black, appropriate for rack ears, credenza mounting, or discreet placement behind displays in low-profile AV installations.

Integration and Compatibility

As a signal-agnostic extender, the AVX-DVI-TP-100M sits between any DVI-D source — PC, media player, signal processor — and any DVI-D or HDMI-with-adapter display. RS-232 compatibility depends on the control protocol of the connected devices; confirm baud rate and command set support with your control system documentation before deployment.

If your project requires fiber-optic extension for longer runs or electrically isolated signal paths, explore the broader range of KVM and AV extension solutions available alongside this unit.

Frequently Asked Questions

Q: What signal types does the AVX-DVI-TP-100M extend?

A: The AVX-DVI-TP-100M extends DVI-D digital video, analog audio, and RS-232 serial control simultaneously over twisted-pair cabling.

Q: Does the AVX-DVI-TP-100M require proprietary cable, or will standard Cat5e/Cat6 work?

A: The unit is designed for twisted-pair transmission consistent with structured cabling standards. Confirm specific cable category requirements with Black Box documentation before purchasing cable in bulk.

Q: Can the RS-232 channel be used for bidirectional control?

A: RS-232 by nature supports bidirectional serial communication, but verify the specific implementation in the Black Box product documentation to confirm full duplex support for your control system.

Q: Is the AVX-DVI-TP-100M compatible with HDMI displays?

A: DVI-D and HDMI share the same digital signal standard; a passive DVI-to-HDMI adapter at the receiver output is typically sufficient, but verify the display's EDID and audio input path before assuming plug-and-play operation.

Q: What is the warranty on the AVX-DVI-TP-100M?

A: Warranty terms are set by Black Box and vary by product line. Contact Black Box or request documentation at point of purchase to confirm the applicable warranty period for this SKU.

The AVX-DVI-TP-100M sits in a specific niche that a lot of integrators overlook until they are mid-project: you need DVI-D video, audio, and RS-232 control at the far end of a cable run, and you want to do it over twisted pair rather than pulling three separate cables. The RS-232 channel is the real differentiator here — most entry-level DVI extenders drop serial entirely, which forces you to either run a dedicated control cable or leave the display uncontrolled from the head end.

Technical Highlights:

• DVI-D Signal Path: Uncompressed digital transmission means no generation loss or compression artifacts — what leaves the source is what arrives at the display, critical for applications like medical imaging displays or high-resolution presentation systems where pixel accuracy matters.
• RS-232 Integration: Serial control riding the same twisted-pair infrastructure as the video signal keeps conduit count down and simplifies troubleshooting — one cable path to trace, not three.
• Audio Extension: Integrated audio removes the need for a parallel analog audio run to the remote display or amplifier, which in a finished-wall installation can mean the difference between a clean job and a drywall repair.

Deployment Considerations:

• Confirm the maximum extension distance from Black Box documentation before committing to cable routes — the product name references 100M, but verify whether that applies to all signal types (video, audio, RS-232) equally or whether RS-232 has a shorter reliable range.
• EDID management is a common pain point on DVI extenders: if the source loses EDID on boot-up or standby, the display may not negotiate the correct resolution. Check whether this unit includes EDID emulation or buffering before finalizing the design.

This extender is well-suited for fixed-installation AV in corporate boardrooms, command-and-control consoles, or digital signage racks where the source equipment must be secured in a server room while the display lives 50–100 meters away and requires serial control from the same location.
