Amphenol 8-Way Digital Splitter MoCA 2.5 ABS318H Instruction Manual

Introduction

The Amphenol ABS318H 8-Way Digital Splitter is designed for distributing high-frequency signals across a coaxial home or business network. This splitter supports MoCA 2.5 technology, enabling efficient networking and video distribution applications with a frequency range of 5 to 1675 MHz. Its robust construction ensures durability for both indoor and outdoor installations.

Product Overview

The Amphenol ABS318H is an 8-way coaxial splitter featuring one input port and eight output ports. It is engineered to maintain signal integrity with low insertion loss and high isolation, crucial for optimal performance in MoCA networks.

Setup Instructions

1. Identify Components: Ensure you have the Amphenol ABS318H splitter, appropriate coaxial cables (RG-6 recommended), and any MoCA adapters or devices you intend to connect.
2. Locate Input Source: Identify the main coaxial cable carrying the signal from your service provider (e.g., cable modem, antenna). This will connect to the 'IN' port on the splitter.
3. Connect Input: Screw the main coaxial cable securely onto the 'IN' port of the ABS318H splitter. Ensure the connection is finger-tight, then use a 7/16 inch wrench to tighten an additional quarter turn. Avoid overtightening.
4. Connect Output Devices: Connect individual coaxial cables from the 'OUT' ports of the splitter to your MoCA-enabled devices, televisions, cable boxes, or other network equipment. Repeat the tightening process for each connection.
5. Secure Unused Ports (Optional but Recommended): For optimal signal integrity and to prevent interference, it is recommended to terminate any unused 'OUT' ports with 75 Ohm F-type terminator caps. These caps help maintain proper impedance and reduce signal reflections.

Operating Instructions

Once all connections are securely made, the Amphenol ABS318H splitter operates passively to distribute the coaxial signal. No external power is required. The splitter is designed to handle frequencies from 5 to 1675 MHz, making it compatible with MoCA 2.5 networks, standard cable television, and other coaxial signal applications.

• The splitter ensures minimal signal degradation through its low insertion loss design.
• High port-to-port isolation prevents interference between connected devices.
• The device is transparent to MoCA signals, allowing MoCA adapters to communicate effectively across the network.

Maintenance

The Amphenol ABS318H splitter is designed for long-term, reliable operation with minimal maintenance. Follow these guidelines to ensure optimal performance:

• Environmental Conditions: Install the splitter in a location protected from extreme temperatures and direct moisture. While the rugged metal housing offers durability, prolonged exposure to harsh elements should be avoided.
• Connection Integrity: Periodically check all coaxial cable connections to ensure they remain tight and secure. Loose connections can lead to signal loss or interference.
• Cleanliness: Keep the splitter free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners directly on the device.
• Port Protection: The 15 PSI pressure-sealed coaxial F-Ports provide protection against moisture ingress. Ensure that any unused ports are properly terminated or capped to maintain this protection.

Troubleshooting

If you experience issues with your network or signal distribution, consider the following troubleshooting steps:

• No Signal or Weak Signal:
  • Verify all coaxial cable connections are tight at both the splitter and the connected devices.
  • Inspect cables for damage (kinks, cuts, frayed connectors). Replace damaged cables.
  • Ensure the input signal source is active and functioning correctly.
  • If using a MoCA network, confirm that all MoCA adapters are powered on and properly configured.
• Interference or Pixelation:
  • Ensure all unused output ports on the splitter are terminated with 75 Ohm F-type terminator caps. This prevents signal reflections and ingress.
  • Check for external sources of interference near coaxial cables or the splitter.
  • Verify that the splitter is rated for the frequency range of your services (5-1675 MHz for MoCA 2.5).
• MoCA Network Issues:
  • Confirm that your MoCA adapters are compatible with MoCA 2.5 standards.
  • Ensure there is a MoCA filter installed at the point of entry to your home if you are using MoCA with a cable internet service, to prevent your MoCA signal from leaving your home network and to protect it from external interference.
