This shielding strategy is required to minimize bit error rates when the cable is routed near process instrumentation operating on 4-20 mA HART loop protocol signals. By maintaining constant characteristic impedance through the coaxial construction, the cable ensures that RS-485 differential signals remain protected from external common-mode noise, preventing data corruption within the Ovation control bus.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003eQ: Can this cable be utilized for long-distance I\/O extensions?\u003c\/p\u003e\n\u003cp\u003eA: The 5A26141G06 is designated as a local I\/O bus cable with a fixed length of 4.5 feet. Exceeding recommended cable lengths for RS-485 communication can result in signal attenuation and timing violations; consult the Ovation system manual for maximum bus length specifications.\u003c\/p\u003e\n\u003cp\u003eQ: Are there specific grounding requirements for the DB9 shield termination?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the cable shield must be bonded to a low-impedance earth ground at the cabinet entry point. Failure to properly terminate the shield can lead to ground loops and significant noise injection into the serial data stream.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect both DB9 male connectors for bent pins or debris before engagement with the I\/O module ports.\u003c\/li\u003e\n\u003cli\u003eAlign the connectors carefully and secure the retaining screws to ensure a stable physical connection.\u003c\/li\u003e\n\u003cli\u003eRoute the cable through dedicated signal wireways, maintaining separation from high-voltage AC lines or motor power cables to mitigate crosstalk.\u003c\/li\u003e\n\u003cli\u003eEnsure the cable maintains a minimum bend radius consistent with 24 AWG coaxial standards to prevent internal conductor fatigue.\u003c\/li\u003e\n\u003cli\u003eVerify communication link status via the Ovation controller software after installation to confirm that no packet loss occurs at the 19.2 kbps operating speed.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"EMERSON","offers":[{"title":"Default Title","offer_id":52956148957493,"sku":"5A26141G06","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/5A26141G06.png?v=1780466774","url":"https:\/\/www.5gplc.com\/products\/5a26141g06-emerson-local-i-o-bus-cable","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
