2.1 System Hardware Description
The InterReach Unison Accel system consists of two modular components:
• 19" rack-mountable Hub (connects to up to 8 Remote Access Units)
• Converts RF signals to electrical on the downlink; electrical to RF on the
uplink
• Microprocessor controlled (for alarms, monitoring, and control)
• Software configurable band
• Simplex interface to RF source
• Periodically polls all downstream RAUs for system status, and automatically
reports any fault or warning conditions
• Supplies DC power to RAU
• Remote Access Unit (RAU)
• Converts electrical signals to RF on the downlink; RF to electrical on the
uplink
• Microprocessor controlled (for alarms, monitoring, and control)
• Protocol/band specific units
The minimum configuration of a Unison Accel system is one Hub and one RAU
(1-1). The maximum configuration of a system is one Hub and 8 RAUs (1-8). Multi-
ple systems can be combined to provide larger configurations.
