Functional Description
IS200SSCAH1ACB is a Simplex Serial Communication Input/Output terminal board developed by GE. It is a part of Mark VIe control system. Simplex Serial Communication Input/Output terminal board manages serial communication channels within the Mark VIe system. The terminal board is designed to be compact, making efficient use of space within the system enclosure. It offers up to six communication channels, providing ample capacity for connecting various devices and peripherals. Each channel on the board can be flexibly configured to support RS-232C, RS-485, or RS-422 signaling protocols, catering to a wide range of communication requirements and device compatibilities.
Features
- Single Configuration Option: The board is available only in a simplex configuration, simplifying installation and setup processes. Despite its simplex nature, the board offers robust functionality and versatility in managing communication channels effectively.
- High-Density Euro-Style Box Terminal Blocks: The terminal board features high-density Euro-style box terminal blocks, known for their reliability and ease of wiring. These terminal blocks provide secure and organized connections for the communication channels, ensuring stable signal transmission and minimal interference.
- On-Board ID Chip for System Diagnostics: An on-board ID chip is integrated into the board, serving the crucial purpose of identifying the board to the PSCA I/O pack. This ID chip enables seamless communication between the terminal board and the PSCA I/O pack, facilitating system diagnostics and troubleshooting processes. By accurately identifying the terminal board, the system can efficiently monitor and manage the status of the communication channels, enhancing reliability and performance.
Installation
- Mounting Options: The terminal board is typically mounted on a DIN-rail using a sheet metal carrier and plastic insulator mount. Alternatively, it can be bolted directly into a cabinet, providing flexibility in installation based on the system's layout and requirements.
- Mounting Hardware: To secure card onto a DIN-rail, a sheet metal carrier and plastic insulator mount are utilized. These components ensure stable positioning and vibration resistance, enhancing the durability of the installation. For direct cabinet mounting, appropriate bolts or screws are employed to affix the board securely in place, minimizing the risk of movement or displacement.
- Euro-Block Terminal Blocks: There are two types of Euro-Block terminal blocks available for use with the terminal board, each offering distinct advantages:
- SSCAH1: This variant features a permanently mounted terminal block with 48 terminals. It provides a fixed connection solution, suitable for applications where terminal block configurations remain consistent.
- SSCAH2: The SSCAH2 terminal block incorporates a right-angle header that accepts a range of commercially available pluggable terminal blocks, also equipped with 48 terminals. This option offers greater flexibility, allowing users to interchange terminal blocks as needed and adapt to evolving system requirements.
- Secure Connection: Regardless of the type of terminal block used, ensuring a secure and reliable connection is paramount. Proper tightening of terminal screws or insertion of pluggable terminal blocks is essential to maintain electrical conductivity and prevent signal loss or intermittent connections.
- Alignment and Cable Management: During installation, attention should be paid to aligning the board correctly to facilitate easy access to communication channels and terminal blocks. Cable management practices should be observed to minimize clutter and ensure neat routing of wires or cables connected to the terminal blocks, reducing the risk of interference or accidental damage.
Configuration
- Configuration Method: The terminal board's configuration is achieved through the use of jumpers. These small connectors are placed over pairs of pins to either apply or remove specific settings. For the precise location of these jumpers, users should refer to the operation section of the terminal board's documentation.
- Jumper Options: The available jumper choices are organized into three categories, each addressing specific aspects of signal termination and connection:
- Termination Resistors (JP1A through JP6A and JP1B through JP6B): These jumpers control the application or removal of termination resistors between signal lines A and B, and signal lines C and D, respectively, for the six serial communication channels. Termination resistors help prevent signal reflections and ensure signal integrity, particularly in long communication lines or environments with high electrical noise.
- Return Connection Selection (JP1R through JP6R): These jumpers determine whether the return connection has a resistive or capacitive connection to SCOM (Serial COMmunication). The selection between resistive and capacitive connection options may depend on factors such as system requirements, environmental conditions, and compatibility with connected devices.
- Configuration Considerations: When configuring the terminal board, users should carefully assess the specific requirements of their application and ensure that jumper settings align with these needs. It's important to follow the manufacturer's guidelines and recommendations regarding jumper configurations to avoid signal interference, data loss, or other performance issues.
- Testing and Validation: After configuring the terminal board, users should conduct thorough testing and validation procedures to verify that communication channels are functioning as intended. Testing may involve sending and receiving data through the serial communication channels while monitoring for any anomalies or errors.
