TEL TVB-1202-1 ANET VME Bus Termination Board

The TEL TVB-1202-1/ANET is an active termination board designed for VMEbus systems, providing proper signal termination to maintain signal integrity and reliable operation. This module ensures that VME backplane signals are correctly terminated, preventing reflections and signal degradation that can cause system errors in high-speed industrial computer applications.

Technical Specifications

The board is designed for installation in standard VME card cages, occupying a single slot. It terminates all critical VMEbus signals including address lines, data lines, arbitration lines, and interrupt lines. The active termination circuitry is powered from the VME backplane, drawing minimal current while providing stable termination characteristics. The module is compatible with both 3U and 6U VME systems when used with appropriate adapters.

System Integration

The TVB-1202-1 is typically installed in the first and last slots of a VME backplane to properly terminate the bus. In systems where the backplane does not include integral termination, this board provides the necessary termination for reliable operation. It is commonly used in industrial control systems, test equipment, and military applications where VME-based computing is deployed.

Reliability Features

Constructed with high-reliability components and conformal coating, the TVB-1202-1 is designed for continuous operation in industrial environments. The active termination circuitry includes protection against power supply fluctuations and maintains stable termination characteristics even under varying temperature conditions. This ensures consistent system performance and reduces the risk of bus-related errors in critical applications.
