If the installation contains another device that uses Bluetooth wireless technology, mountthe devices apart from each other as much as possible (at minimum, leave a small gap between the devices)to prevent signal interference.NOTEIf poor Connext wireless performance is observed, check the auto reconnect settings anddisable any devices that are not intended to be used.2.6 Cabling and WiringRefer to the interconnect examples in Appendix B for wire gauge guidance.If using larger barrel contacts, ensure that no two contacts are mounted directly adjacent to each other. Thisminimizes the risk of contacts touching and shorting to adjacent pins and to ground.Use wire and cable meeting the applicable aviation regulation. When routing wire and cable, observe thefollowing precautions:• Keep wire and cable as short and direct as possible• Avoid sharp bends• Avoid routing near power sources (e.g. 400 Hz generators, trim motors, etc) or near power offluorescent lighting• Route the GPS, ADS-B, SiriusXM antenna cables as far as possible away from all COMtransceivers and other antenna cables.• RG400 or RG142 coaxial cable with 50 Ω nominal impedance and meeting applicable aviationregulations should be used when installing optional external antennas.NOTEAvoid installing the unit near heat sources. If this is not possible, ensure that additionalcooling is provided. Allow adequate space for installation of cables and connectors. Theinstaller will supply and fabricate all of the cables.
