Functional Description

5463-716 is a SIO Module developed by Woodward. Functioning as a Serial In/Out (SIO) Module, its purpose is to orchestrate the harmonious convergence of four distinct serial communication ports with the VME (VersaModule Eurocard) bus- a feat that embodies a fusion of precision and integration.Delving into its core functionality, this SIO Module assumes the pivotal role of managing and governing the operational dynamics of these four communication ports. These ports act as conduits through which data traverses, facilitating seamless interaction between devices and the broader control system. By orchestrating this symphony of data flow, the SIO Module ensures that the communication process is controlled, coherent, and reliable.

Product Attributes

  • An aspect of paramount importance resides in the synchronization of baud rates within Ports C and D. With communication speeds set at either 38.4 Kbaud or 57.6 Kbaud, the harmony of these rates across both ports becomes imperative. This synchronization serves as the cornerstone of secure and precise data transmission between devices linked to these ports. Ensuring that the baud rates align effectively establishes a robust bridge for accurate information exchange, culminating in dependable data transfer.
  • The integration of the SIO Module into the larger system landscape brings forth a transformative impact. It introduces a pivotal gateway through which a plethora of serial communication devices can seamlessly interface with the commanding VME bus. This integration underlines a commitment to achieving synergy among disparate components within the system, ultimately resulting in elevated cohesion and reliability.
  • Embodies a collection of characteristics that redefine communication in the realm of control systems. Its proficiency in high-speed serial communication, compatibility with diverse systems, tailored configurability, and unyielding commitment to data integrity make it an exemplar of modern engineering. As it bridges the gap between systems, it doesn't merely transfer data; it instills a new level of confidence in the accuracy, efficiency, and reliability of communication across the intricate tapestry of control environments.

Port Specifications

Here are the specifications for each port:

  • Port A (J1): This port is an RS-232 serial communication port. It follows the RS-232 standard for serial communication and is designed for connecting devices using the RS-232 protocol.
  • Port B (J2): Similar to Port A, this is also an RS-232 serial communication port. It provides another RS-232 interface for connecting devices following the RS-232 standard.
  • Port C (J3): Port C is a versatile port that supports multiple serial communication protocols. It can be configured to work with RS-232, RS-422, or RS-485 communication protocols. These protocols offer different standards for serial communication over longer distances or in multi-drop network topologies.
  • Port D (J4): Similar to Port C, Port D is also capable of supporting RS-232, RS-422, or RS-485 communication protocols. It provides flexibility in choosing the appropriate protocol based on specific requirements.


  • When one or more transmitters are connected to a single receiver, termination should be located at the receiver for RS-422. When a single transmitter is linked to one or more receivers, termination should take place at the receiver furthest away from the transmitter. Termination for RS-485 should be at both ends of the cable. If termination cannot be placed at the end of a cable, it should be placed as close to the ends as possible. A three-resistor voltage divider between a positive voltage and ground is used to terminate the circuit. The resistor network's impedance should be equal to the cable's characteristic impedance.
  • This is usually between 100 and 120. The goal is to maintain a voltage level between the two differential lines so that the receiver remains stable. The differential voltage can be between 0.2 and 6 V, with a maximum voltage of less than 10 V between either receiver input and circuit ground. Each port on the SIO board has its own termination resistor network. The resistor network is connected via the 9-pin connectors on pins 6 and 9.


  • High-Speed Serial Communication: At the heart of this module lies its capability to facilitate high-speed serial communication, a conduit for expeditious and effective data transfer between interconnected systems and components. This characteristic amplifies the efficiency of data exchange, contributing to the swift dissemination of crucial information within complex control environments.
  • Seamless Compatibility: The hallmark of this SIO Module resides in its seamless compatibility with an extensive array of Woodward control systems. This intrinsic versatility underscores a commitment to harmony, ensuring that integration is effortless and operational cohesion is achieved across a spectrum of control setups. The module becomes a universal bridge uniting diverse components into a coherent orchestration.
  • Tailored Configuration: The SIO Module isn't a one-size-fits-all solution; it's a versatile tool that's meticulously configured to cater to specific application prerequisites. A versatile selection of input and output options empowers control engineers to align the module with the unique demands of their operational landscape. This adaptability underpins the module's ability to seamlessly integrate into diverse contexts.
  • Data Integrity Assurance: A foundational tenet of the SIO Module's design revolves around safeguarding data integrity. In a realm where precision and accuracy reign supreme, the module stands as a guardian. By incorporating features dedicated to validating data integrity and preventing errors during transmission, the module ensures that the data traversing its pathways remains untainted, accurate, and steadfastly reliable.
  • Reliable Data Transmission: The SIO Module isn't merely a conduit; it's a guarantor of dependable data transmission. With its vigilance against errors and its commitment to accuracy, the module not only empowers systems with communication but bestows them with communication of the utmost reliability. It transforms data into a dependable currency, fostering a realm where information exchange is synonymous with unwavering trust.
