Description
Product Overview
Communication faults and processor-card failures in marine automation systems can affect alarm reporting, equipment status visibility, and the transfer of operational data. The Samsung RSPC-X32 is documented as the CPU card used in the SSAS-Pro ship automation system. Its role combines processing and communications, connecting the system’s internal bus with Ethernet and serial interfaces used by external equipment. This makes accurate identification essential when maintaining an installed vessel automation system or sourcing a replacement for a failed controller card.
The available service-manual excerpt specifies an MPC860 processor operating at 50 MHz, 16 MB of main memory, 2 MB of EPROM flash memory, 4 MB of data flash memory, and an RTC/NVRAM device. It also lists two Ethernet ports arranged for redundancy and four optically isolated serial communication ports supporting RS-232, RS-422, or RS-485. The card uses a 48-pin DIN bus connector and requires a +24 VDC input. The manual reports a power requirement for +24 V, +5 V, and +3.3 V rails, with total consumption of approximately 14 W including the baseboard. These are specifications from the available service-manual excerpt; confirm the hardware revision and nameplate before using them as acceptance criteria.
For replacement planning, matching the model number alone is not sufficient. Verify the board revision, connector keying, firmware or application compatibility, and the configuration of the existing SSAS-Pro installation. Serial interfaces may be configured differently between connected devices, and the presence of redundant Ethernet ports does not by itself establish the network topology or failover behavior of a particular installation. Before commissioning, inspect the card and connectors, confirm the correct supply voltage, and check system diagnostics and alarm communication after installation. The Samsung RSPC-X32 should be evaluated as a system-specific marine automation component, not assumed to be interchangeable with a general-purpose industrial controller.
Product Introduction
When a ship automation processor stops communicating, replacing it with a card that has the wrong revision or interface configuration can prolong troubleshooting. The Samsung RSPC-X32 is the SSAS-Pro CPU card documented with an MPC860 processor, two Ethernet ports, and four optically isolated serial ports.
For legacy-system maintenance, confirm the 24 VDC supply, 48-pin bus connection, and software compatibility before installation. These checks help reduce avoidable commissioning delays and protect connected monitoring equipment.

Frequently Asked Questions
What is the Samsung RSPC-X32 used for?
It serves as a CPU and communications card in the SSAS-Pro ship automation system. The documented hardware includes Ethernet and serial interfaces for system communications, along with digital inputs and outputs.
Can I hot-swap the ?
Do not assume hot-swap capability. The available manual excerpt does not confirm live replacement support. Follow the vessel’s approved maintenance procedure, isolate power as required, and verify whether the installed system supports replacement without a shutdown.
Does the support firmware v3.1?
The available specification excerpt does not confirm firmware v3.1 compatibility. Check the installed board revision, firmware release notes, and SSAS-Pro application version before performing an upgrade or exchanging cards.
What supply voltage does the require?
The service-manual excerpt specifies +24 VDC input power and lists internal +24 V, +5 V, and +3.3 V rails. Confirm the input connection and polarity against the board markings and system documentation before energizing the card.
Can another SSAS-Pro card replace the ?
No—not simply because it belongs to the same system. The performs CPU and communications functions, while the SPDI, SPRDO, SPAI, SPAO, SPRI, and SPIRU modules provide specific I/O functions. A replacement must match the required processor-card role and system configuration.
How can I verify the authenticity and condition of a replacement?
Request clear photographs of the model label, board revision, connector layout, and any serial or identification markings. Ask for a condition statement and functional test results relevant to the SSAS-Pro system. Photographs and seller statements are useful checks but do not independently prove original manufacturing provenance.
Will replacing the preserve the existing configuration?
Do not assume the configuration will transfer automatically. The manual lists nonvolatile memory and flash storage, but the available information does not establish exactly which application settings are stored on the card or how they are restored. Back up supported configuration data where possible and follow the vessel’s documented recovery procedure before replacing the processor card.
