Abaco Systems / Ramix PMC661J Ethernet Interface Card

The Abaco Systems / Ramix PMC661J is a single-port 10/100BaseTX Ethernet interface card designed for PCI Mezzanine Card (PMC) form factor systems. This interface card facilitates Ethernet connectivity, enabling devices to transmit and communicate data across a network. It is engineered to provide reliable, high-performance network integration for embedded computing applications.

### Technical Specifications

**General**
* **Manufacturer:** Abaco Systems / Ramix
* **Model:** PMC661J
* **Product Family:** PMC661, PMC-661, PMC 661, PMC661J, PMC-661J, PMC 661J
* **NSN:** 7025-01-493-7656, 7025014937656

**Interfaces**
* **Ethernet Type:** 10/100BaseTX
* **Connector Type:** Front I/O via flush-mounted RJ45 connector
* **Data Transfer Modes:**
* Full duplex operation in 10Mbit and 100Mbit modes
* Half duplex operation supported
* **Auto-Negotiation:** Implemented for automatic configuration to the highest possible operating mode, including bandwidth and full duplex determination

**Performance**
* **Ethernet Controller:** PMC660 Ethernet/PCI engine
* **DMA Engine:** Powerful DMA engine with deep FIFO buffers to ensure continuous, full bandwidth operation with minimal PCI overhead
* **Throughput:** Assures continuous, full bandwidth operation

**Physical**
* **Form Factor:** PCI Mezzanine Card (PMC)
* **I/O:** Front I/O via RJ45 connector

**Compatibility and Integration**
* **PCI System Integration:** Can be integrated into card edge PCI systems using adapters such as the GE Fanuc Embedded Systems PMC239 adapter for rapid prototyping and development
* **Direct Cabling:** Two PMC661J boards can be directly cabled with a simple “cross-over” cable to create a full duplex 100Mbit dedicated data path
* **Network Interconnection:** Can utilize hubs or switches for more complex, dedicated interconnects. Point-to-point and switched hubs in full duplex mode can mitigate determinism concerns inherent in traditional Ethernet solutions, making it suitable for high-performance interconnects requiring real-time determinism

**Power**
* **Power Consumption:** 1.5 Watts @ 3.3V

**Software Support**
* **Drivers:** Abaco Systems (formerly GE Fanuc Embedded Systems) provides software drivers for popular operating systems such as VxWorks, LynxOS, Digital UNIX, Windows NT, and Solaris. These drivers are designed to integrate seamlessly with the host operating system’s LAN protocol stack, allowing full utilization of host OS facilities. User control over operating parameters, including auto-negotiation capabilities, is available through these drivers.
