Abaco Systems / SBS / Bit 3 418-101 VME Bus Repeater Module

The Abaco Systems / SBS / Bit 3 418-101 VME Bus Repeater Module is designed to extend a VMEbus backplane from a primary chassis to a secondary chassis, effectively creating a single, unified system controlled by the primary chassis. This module facilitates the expansion of VMEbus systems, allowing for greater flexibility and increased capabilities in embedded computing applications. The primary chassis functions as a standalone unit, while the secondary chassis, lacking its own system controller, relies on the primary for operation.

### Technical Specifications

* **Product Name:** Abaco Systems / SBS / Bit 3 418-101 VME Bus Repeater Module
* **Functionality:** Extends VMEbus backplane from one chassis to a second VMEbus chassis.
* **System Architecture:** Both chassis operate as a single unit, controlled by the system controller in the primary chassis. The primary chassis can operate independently; the secondary chassis cannot operate without the primary.
* **Model Variants:**
* Model 418: Includes two size 6U Repeater cards.
* Model 418-50: Includes one size 6U Repeater card and one Repeater card in a 6U/9U metal holder.
* The 418-101 is a specific model within the 418 series.
* **VMEbus Support:**
* Supports VME-32 and VME-64 (including VME64 Revision D1.4 enhancements).
* Supports D8 (EO), D16, D32, and D64 VMEbus data sizes.
* Supports A16, A24, A32, and A64 address sizes.
* Supports BLT, RMW, and UAT transfer types.
* Supports ROAK, ROR, RORA, and RWD release.
* Supports SGL, PRI, and RRS arbiters.
* **Interconnect Cables:**
* Two round EMI-shielded copper-conductor cables are used to interconnect the Repeater cards.
* Standard lengths include 8-foot (Model 400-135) and 25-foot (Model 400-136).
* Cables are purchased separately from the Repeater package.
* Standard cables feature Subminiature D connectors.
* **Enable/Disable Function:**
* Optional software-controlled enable/disable function.
* A write to the Repeater I/O register switches the Repeater on or off.
* This feature can be disabled by a jumper, making the Repeater transparent to the VMEbus systems and eliminating I/O address usage.
* **System Integrity:**
* Provides a glitch-free environment on the primary chassis during power on/off of the secondary chassis.
* Handles bus requests, bus grants, and interrupts that could otherwise cause VMEbus timing errors on the primary chassis during secondary chassis power down.
* **Card Form Factor:** 6U VMEbus Repeater cards.

### Electrical Specifications

* **Power Requirements:** 2.75A at 5V.

### Environmental Specifications

* **Operating Temperature:** 0°C to 60°C.
* **Storage Temperature:** -40°C to 85°C.
* **Humidity:** 0% to 90% non-condensing.

### Physical Specifications

* **Card Size:** 6U VMEbus form factor.

### Compatibility

* **Bus Masters and Slaves:** Can reside in either the primary or secondary chassis.
* **VMEbus Standards:** Supports VME-32 and VME-64.

### Documentation

* Datasheets and manuals are available for the Abaco Systems 418 Series.
