2000A89 Module Adapter
Assembly
Introduction
The 2000A89 Module Adapter Assembly consists of a 2000 Series rear
media module and front slot adapter that allows compatible 8900 modules
to be installed in the front slot of a 2000 Series frame (see
Compatible 8900
Modules on page 5 ). The 2000A89 module adapts the 8900 mechanical and
electrical connections to the 2000 Series frame. The module has an on-board
±12V power supply to meet 8900 voltage requirements. The 2000A89
assembly includes:
■ A rear mount module with:
■ Two BNCs providing a floating-shield 75
Ω
loop-through input
connection,
■ Eight 75
Ω
BNC input/output connectors, and
■ ±12V power supply that is fused on the input side and short-circuit
protected on the output side.
■ A front frame slot guide assembly to compensate for the width of the
narrower 8900 module.
