– Key Features
• Line Conditioning Architecture — Mitigates voltage spikes, electrical noise, and ground loop interference across all four serial channels
• Replaceable Line Conditioners — Individual serial line conditioners support field maintenance and component upgrades
• Address Configuration Jumpers — Selectable A32, A24, and A16 addressing modes for flexible VMEbus integration
• System Controller Mode — Jumper-configurable for System Controller operation and VIC interprocessor communication facilities
• Power-On Self-Test (POST) — Loop mode test capability with LED status indication: yellow/green for normal operation, red for fault detection. POST jumper must be removed for production operation
• ESD Protection Requirements — Requires anti-static handling procedures, including static control bags and ESD-controlled workstations during installation and service
– Typical Applications
Ideal for VMEbus-based systems requiring enhanced serial line stability in harsh electrical environments, mission-critical data acquisition, industrial control systems, and avionic/defense platforms where EMI rejection and ground isolation are mandatory.
– Compatibility & Integration
This module integrates directly into VMEbus architectures and is compatible with Macrolink’s full range of replaceable serial line conditioner products. Configuration flexibility through jumper settings enables deployment across diverse VMEbus memory addressing schemes and multiprocessor communication topologies.
