System Configuration
System is constructed using 2 wires for audio and 2 wires for video and requires minimal work for installation. In addition, a maximum of 6 video trunk lines can be used in fact from the video bus controller and audio signal lines and use a distribution point from the bus controller. Likewise, there is an option for audio systems can also be configured.
The maximum wire distance specifications published in the literature equally important for the GT system are based on PE insulated (low capacitance), non‐shielded, 20 or 18AWG wire, and above all for full station capacity.
Furthermore, smaller gauge and/or higher capacitance wire can be used for smaller systems at shorter distances.
To summarize, for complete distance specifications on alternative cables, see attached charts. * To extend video distance to tenant stations, add GT‐VBC’s. See bottom of page 8 in Installation Manual.
