Functional Description

IS230SSCA2AG01 is a serial communications terminal board developed by GE. It is a part of the Mark VIe control system.The SSCA board is designed for serial communication within the system, offering versatility and reliability in data exchange. The board supports up to six communication channels, providing ample connectivity options for various system requirements. The PSCA I/O pack in Mark VIe systems interfaces with the SSCA. Connecting via the DC-37 pin connector, the I/O pack communicates with the controller through Ethernet. This configuration exclusively supports simplex systems.

Features

• Signal Configuration: Each channel can be flexibly configured for RS-232C, RS-485, or RS-422 signaling, allowing compatibility with different communication protocols and devices.
• Simplex Design: Available only in a simplex version, simplifying installation and usage while ensuring efficient communication functionality.
• Terminal Blocks: High-density Euro-style box-type terminal blocks are utilized for secure and organized wiring connections, facilitating straightforward installation and maintenance procedures.
• On-board ID Chip: An integrated ID chip on the board serves diagnostic purposes, identifying the board to the PSCA I/O pack. This feature enhances system monitoring and troubleshooting capabilities.

Configuration

• Signal Line Termination (JP1A - JP6A, JP1B - JP6B): These jumpers apply or remove termination resistors between signal lines A and B, and between signal lines C and D, for the six serial communication channels.
• Return Connection Selection (JP1R - JP6R): These jumpers determine whether the return connection has a resistive or capacitive connection to SCOM.

Installation

• Mounting: Secure the SSCA board on a DIN-rail using a sheet metal carrier and plastic insulator mount. This setup does not include a shield termination strip.
• Wiring: Utilize 18 AWG wiring, typically shielded twisted pair, for connecting the SSCA board. Ensure proper termination of the I/O cable shield, either using an external mounting bracket provided by the customer or by GE.
• Chassis Ground Connection: Utilize mounting holes E1 and E2 for the chassis ground connection. It's essential to connect one of the SCOM terminals (37-48) to a suitable shield ground for effective grounding.

Frequently Asked Questions

What is IS230SSCA2AG01?
It is a serial communications terminal board developed by GE under the Mark VIe series.

What is the purpose of the ID device on the JA connector?
The ID device on the JA connector serves as a read-only chip containing crucial information such as the terminal board's serial number, board type, revision number, and the specific location of the J connector.

How is the ID device interrogated?
The ID device is interrogated by the PSCA I/O pack, which reads the information stored on the chip.

What happens if there is a mismatch between the ID device and the I/O processor?
In the event of a mismatch between the information retrieved from the ID device and the expectations of the I/O processor, a hardware incompatibility fault is generated.

What does a hardware incompatibility fault signify?
A hardware incompatibility fault indicates that there is a discrepancy between the expected hardware configuration, as defined by the information stored on the ID device, and the actual hardware present in the system.
