1. Introduction
This manual provides comprehensive instructions for the installation, operation, and maintenance of the PVI MINIMOD 2 Vecoax HDMI to Coax Modulator. This device is designed to convert an HDMI video signal from any HDMI source into a real HDTV channel with Full HD up to 1080p, allowing distribution over existing coaxial cable networks to multiple televisions.
The MINIMOD 2 offers a simple and efficient solution for distributing high-definition video content throughout a building without the need for new wiring.
2. Product Overview
The PVI MINIMOD 2 Vecoax is a high-definition HDMI video digital TV RF coax modulator. It takes an HDMI input signal and modulates it into a digital television channel (ATSC or QAM), which can then be broadcast over a standard coaxial cable system.

- Supports Closed Captioning from the HDMI source.
- Selectable QAM Cable & ATSC RF Output (Agile: 30 MHz to 951 MHz).
- User-configurable channel number (1 to 9999) and channel name via color display.
- High RF output level (+45dB mV) capable of driving extensive coaxial networks.
- Plug-and-play operation for quick setup.
3. Setup and Installation
Follow these steps to set up your MINIMOD 2 Vecoax modulator:
- Unpack the Device: Carefully remove the MINIMOD 2 from its packaging. Ensure all components are present.
- Connect HDMI Source: Connect your HDMI video source (e.g., Blu-ray player, set-top box, computer) to the HDMI input port on the MINIMOD 2 using a high-quality HDMI cable.
- Connect Coaxial Output: Connect the RF output of the MINIMOD 2 to your existing TV distribution coaxial cable network. This can be done via a wall TV socket or directly to your TV distribution box.
- Power On: Connect the provided power adapter to the MINIMOD 2 and then plug it into an electrical outlet. The 'Power' indicator light on the front panel should illuminate.
- Configure Channel Settings:
- Use the control keypad (Navigator and Enter buttons) on the front panel to access the settings menu on the color display.
- Navigate to the 'Channel Number' setting and select your desired channel number (1 to 9999).
- Navigate to the 'Channel Name' setting and input a desired name for your new channel.
- Select the appropriate modulation standard (ATSC for over-the-air broadcast or QAM for cable systems) based on your region and setup.
- Rescan TVs: On all televisions connected to the coaxial network, perform a channel scan (or auto-tune) to discover the newly added channel from the MINIMOD 2. Refer to your TV's instruction manual for specific channel scanning procedures.
- Verify Signal: Once the scan is complete, tune to the channel you configured on the MINIMOD 2 to verify that the HDMI video source is being successfully distributed.
The MINIMOD 2 can combine its output with existing antenna or cable signals on the same coaxial network, allowing you to watch both standard TV channels and the modulated HDMI channel.

Any changes to the channel number or modulation type will require a re-scan on your connected televisions.
5. Maintenance
The MINIMOD 2 Vecoax modulator is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:
- Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use liquid cleaners or aerosol sprays, as they may damage the unit.
