* **Interface:** VMEbus
* **Reflective Memory Network:**
* **Maximum Nodes:** Up to 256 independent systems (nodes)
* **Serial Data Rate:** 1.2 Gbaud
* **Network Transfer Rate (Non-Redundant):** 29.5 Mbyte/s
* **Network Transfer Rate (Redundant):** 14.8 Mbyte/s
* **On-board Memory:**
* **Configurable SDRAM:** 256 Kbyte to 16 Mbyte
* **Data Transfer:**
* **Direct Memory Access (DMA):** Supported, enabling block transfers without significant CPU overhead. The VMIVME-5588DMA includes DMA capabilities, distinguishing it from the 5576 and 5588 models.
* **Software Transparency:** Data transfer is software transparent, requiring no explicit I/O overhead.
* **FIFOs:** Transmit and Receive FIFOs buffer data to optimize CPU and bus performance during peak data rates.
* **Interrupts:**
* **Node-to-Node Interrupts:** Any node can generate an interrupt in any other node or all nodes on the network with a single command.
* **Physical Connections:**
* **Fiber Optic:**
* **Multimode Fiber:** Up to 1,000 ft (approximately 300 m)
* **Single-mode Fiber:** Up to 10 km (approximately 6.2 miles)
* **Coaxial Cable:** Up to 30 m
* **VMEbus Access:** Supports A24:A32:D64:D32:D16:D8 memory access.
* **Error Handling:**
* **Error Detection:** Supported
* **Redundant Transmission Mode:** Available for suppressing errors
* **Form Factor:** Single-slot 6U VMEbus board
* **Processor Overhead:** Minimal to none; no processor involvement required for network operation.

### Compatibility and Software

* **Supported Operating Systems:** Solaris 2.x, SGI IRIX 4.x, SGI IRIX 6.x, VxWorks, DEC UNIX 4.x.
* **Windows NT Support:** Achieved using GE Fanuc’s VMEbus CPU boards with VMISFT-9420, enabling reflective memory access. Support for interrupts, DMA, and IP protocols requires additional user-supplied software.
* **Driver Software:** VMIVME/SW-RFM1 Network and Shared Memory Driver is compatible with VMIVME-5588DMA. This driver supports programmed I/O (Peek and Poke), Direct Memory Access (DMA), and TCP/IP protocols (VxWorks option).

### Fiber Optic Connectivity Options

* **Transmission Modes:**
* Multimode Fiber (MM Fiber)
* Single-mode Fiber (SM Fiber)
* Mixed Mode (MM/SM Fiber)
* Twinax Cable
* **Optional Converters:** Optional multimode/single-mode converter for extending reach up to 6.2 miles (VMIVME-5592A).
* **Bypass Switch Options:**
* Automatic fiber-optic bypass switch (VMIVME-5599).
* Active fiber-optic bypass switch (VMIVME-5591 or -5593).

### Options and Configurations

* **Memory Options:** Available in configurations from 256 Kbyte up to 16 Mbyte of on-board SDRAM.
* **FIFO Options:** 512 Transfer FIFO or 4 Kbyte Transfer FIFO.
