[FINCH II, FINCH 5332E and FINCH IN-CAB Systems (Discontinued)](https://help.titanlogix.com/finch-ii-finch-5332e-and-finch-in-cab-systems-discontinued?hsLang=en) # SVBus Communication Overview ## The FINCH 5332E was the first external display developed by Titan Logix for use with the TD80 Guided Wave Radar transmitter. Communication between the TD80 transmitter and the FINCH 5332E is accomplished using a proprietary communication protocol known as **SVBus**. This protocol was originally developed by Sherrex Systems, a company acquired by Titan Logix in the late 1990s. Since its introduction, SVBus has been implemented across multiple Titan Logix products and remains the primary communication method used throughout the current Titan instrument lineup. ### **Key Advantages of SVBus** SVBus was designed specifically for industrial environments and provides several important benefits: - High immunity to electrical noise - Reliable communication over long cable distances - Excellent signal integrity in industrial installations - Stable operation in electrically noisy environments - Robust performance in mobile and vehicle-mounted applications ### **Communication Speed** Communication between the TD80 transmitter and the FINCH 5332E operates at approximately **1200 baud**. While this data rate is relatively slow by modern standards, it offers significant advantages for industrial instrumentation. The lower transmission speed improves communication reliability and increases resistance to electrical interference, signal degradation, and data corruption. As a result, SVBus provides dependable communication between the transmitter and display, even in harsh operating environments where electrical noise and long cable runs are common.     --- **Need more help?** Contact one of our Titan Logix's Service Team members for more technical assistance. **Phone:** 1-877-462-4085 (ext. 2) **Email:** [service@titanlogix.com](mailto:service@titanlogix.com) **Request Training:** [Click Here](https://help.titanlogix.com/kb-tickets/new?hsLang=en) -
