ADLINK cPCI-6965 6U CompactPCI Core Dual Core Single Board Computer

RS-232 full modem mode (default): A standard 9-wire full-featured serial port suitable for connecting traditional serial devices, modems, or industrial HMI panels.

RS-422 half duplex mode: differential signal transmission, strong anti-interference ability, suitable for long-distance (up to 1200 meters or more) point-to-point communication.

RS-485 half duplex mode: differential signal, multi-point bus topology, suitable for building industrial fieldbus networks (such as MODBUS RTU networks), connecting multiple sensors or actuators.

RS-485+Half Duplex Mode: An enhanced RS-485 configuration that typically differs in bias or terminal resistance handling to accommodate specific manufacturer's equipment requirements.

This design, which directly selects electrical characteristics through hardware jumpers, is more reliable and intuitive than pure software configuration, greatly facilitating engineers to conduct system debugging and fault isolation on site.

3. Rich onboard storage options

CPCI-6965 provides three flexible storage solutions to meet the differentiated requirements of different applications for capacity, speed, and reliability:

CompactFlash Type II slot: CF cards have become one of the most reliable boot media in embedded systems due to their anti vibration and wide temperature operation characteristics, making them ideal for installing embedded operating systems (such as Windows Embedded, Linux) and core applications.

Onboard 2.5-inch SATA hard drive installation position: With the included DB-6910SAT adapter board, a 2.5-inch SATA HDD or SSD can be directly installed on the PCB. This design provides convenience for applications that require large capacity data storage, such as logging and image caching.

USB NAND Flash module interface: The board comes with a 9-pin USB connector (CN7) that can be used to install a dedicated USB flash drive module. This provides a third option for applications that require additional small capacity, high reliability storage partitions.

I/O interface and system expansion capability

1. Front panel I/O layout (highly integrated)

The cPCI-6965 integrates rich I/O interfaces on the front panel, allowing it to complete complete complete system functions when running independently:

4 x USB 2.0 ports: Supports high-speed peripheral connections such as USB keyboard, mouse, USB flash drive, and dongle.

2 x 10/100/1000BASE-T Gigabit Ethernet ports: composed of two independent Intel ports ®  82573L PCIe Gigabit Controller Driver, supporting Teaming and PCIe remote boot, suitable for high reliability network communication or data transmission.

Dual DVI display output (one for DVI-I and one for DVI-D).

Dual DB-9 serial ports (supporting RS-232/422/485 configurable).

PS/2 keyboard mouse combination port (8HP version only).

Parallel port (limited to 8HP version only).

System status LED indicators: including power (green), general indicator (blue), watchdog timeout alarm (amber), and hard disk read/write indicator (red).

2. Rear Routing Module (RTM) Expansion

To achieve a true "front plug-in board+rear outlet" CompactPCI system architecture, the cPCI-6965 series offers multiple Rear Transition Module (RTM) options that route signals from the J3 and J5 connectors on the backplane to the back of the chassis, facilitating cable management and maintenance.

RTM model width mainly includes key components/interfaces on the rear I/O interface board

CPCI-R6000-965 4HP 2 × USB 2.0, VGA (DVI adapter), 68 pin SCSI external interface LSI53C1020 PCI-X Ultra320 SCSI controller (supports RAID 1), internal 68 pin SCSI, internal 7-pin SATA, floppy drive interface

CPCI-R6000-L 4HP 2 × USB 2.0, VGA internal 7-pin SATA, floppy drive interface (without SCSI)

CPCI-R6000-965D 8HP 4 × USB 2.0, VGA, PS/2 KB/MS, microphone/linear output, 68 pin SCSI LSI53C1020 SCSI controller, internal 68 pin SCSI, internal 7-pin SATA, floppy drive interface

CPCI-R6000D-L 8HP 4 × USB 2.0, VGA, PS/2 KB/MS, microphone/linear output internal 7-pin SATA, floppy drive interface (without SCSI)

Among them, the RTM model equipped with the LSI53C1020 Ultra320 SCSI controller supports data transfer rates of up to 320MB/s and RAID 1 (disk mirroring) functionality, providing a hardware level redundancy solution for critical data storage that requires high reliability. This feature is crucial in data acquisition and real-time control systems such as railway signal systems and power SCADA.

3. PMC expansion slot (8HP version only)

The cPCI-6965D and cPCI-6965DZ models (8HP width) provide a standard 32-bit/33MHz PMC (PCI Mezzanine Card) expansion slot through the included DB-6965PMC adapter card. The PMC slot supports 3.3V and 5V V (I/O) signals (selectable through onboard JPX1 jumper), allowing users to install dedicated PMC modules to enhance system functionality, such as:

Multi channel high-speed serial communication module (such as RS-232/422/485 multi port card).

Specialized data acquisition modules (such as A/D, D/A, digital I/O cards).

Fieldbus interface modules (such as CANbus, PROFIBUS, MIL-STD-1553).

Encryption/security module.

This PMC expansion capability greatly enhances the flexibility and lifecycle of cPCI-6965, allowing the system to adapt to different external interface requirements by replacing PMC modules without changing the basic CPU platform.
