Functional Description

IS215UCVCH1A is a UCV Controller developed by General Electrics. It is a part of Mark VI control system. The controller, with its powerful processor, ample memory, and Ethernet connectivity, orchestrating and coordinating various operations. Its status LEDs provide real-time feedback on the system's health, ensuring that operators and maintenance personnel can promptly respond to any issues. Additionally, the error code display simplifies the troubleshooting process, minimizing system downtime and enhancing overall reliability. In critical industrial and computing environments, the controller plays a pivotal role in maintaining efficient and uninterrupted operations.


  • Double-Slot Board Design: Features a double-slot board design, which is common in industrial and computing applications. This design allows for greater integration and expansion options within the system.
  • Processing Power: At its core, the controller boasts a 133 MHz Intel Pentium processor. This processor is well-suited for handling real-time tasks and computations, making it an ideal choice for systems requiring high-speed data processing.
  • Memory Capacity: The controller is equipped with 8 MB of flash memory and 16 MB of Dynamic Random-Access Memory (DRAM). This memory capacity ensures that the controller can efficiently store and retrieve data, software, and configurations required for its operation.
  • Ethernet Connectivity: The presence of a single 10Base2 (BNC connector) Ethernet port provides seamless connectivity. This Ethernet port allows the controller to communicate with external devices, the toolbox for configuration and monitoring, or other systems through the Ethernet Global Data (EGD) protocol.
  • Status Indicators: Double column of eight status Light Emitting Diodes (LEDs). These LEDs serve as visual indicators of the controller's operational status. In normal operation, they sequentially illuminate in a rotating pattern, providing a visual confirmation of the controller's health.
  • Error Identification: When an error condition arises within the system, the status LEDs shift from their normal sequential pattern to display a flashing error code. This error code is a valuable diagnostic tool that helps identify the nature and source of the problem, allowing for more efficient troubleshooting and maintenance.

COM Ports in System Communication

COM1 - Reserved for Diagnostics:

  • Connector Type: This port utilizes a micro-miniature 9-pin D connector.
  • Function: COM1 is primarily reserved for diagnostic purposes. It serves as a communication channel to facilitate diagnostics, configuration, and monitoring of the system.
  • Baud Rate: The communication speed, or baud rate, for COM1 is set at 9600 bits per second. This baud rate determines how quickly data is transmitted and received over the port.
  • Data Bits: Data transmission through COM1 uses 8 data bits. Data bits represent the size of the data character in each communication frame.
  • Parity: There is no parity used in COM1 communication. Parity is a form of error-checking used to ensure data integrity during transmission.
  • Stop Bit: Each data character in COM1 communication is followed by one stop bit. Stop bits help signal the end of a data frame.

COM2 - Used for Serial Modbus Communication:

  • Connector Type: Similar to COM1, COM2 also employs a micro-miniature 9-pin D connector.
  • Function: COM2 serves a distinct purpose, it is used for serial Modbus communication. In this configuration, the controller operates as a slave device, meaning it responds to commands and requests from a master device or system.
  • Baud Rate Options: Communication via COM2 can occur at either 9600 or 19200 baud rates. The choice of baud rate depends on the specific requirements of the Modbus communication network.
  • Modbus Protocol: Modbus is a widely used communication protocol in industrial automation and control systems. It facilitates the exchange of data between devices in a standardized and structured manner.
