Description
Functional Description
The CNRACKX is an integral part of Crestron’s new generation of control system
technology featuring the newest series of Ethernet/LAN compatible control systems.
The CNRACKX is a modular “card cage” control system offering the ultimate in
flexibility and customization. In addition to the CNXCPU (central processing unit),
the unit has the capacity for 15 expansion cards. The variety of CNX expansion cards
provides a very high degree of functionality and therefore, this type of system is
suitable for relatively large systems. The CNRACKX requires an external power
supply, CNPWS-75 (sold separately).
Expansion Slots
The 15 open “card cage” slots accept any combination of CNX expansion cards. A
slot for the CNXCPU that optionally features Crestron’s exclusive DPA (Direct
Processor Access) port for Ethernet/LAN expansion of the control network. This port
provides high-speed access directly to the processor while maintaining bandwidth
network connections. The DPA permits 10BaseT and is ready to support Firewire,
ATM, 100BaseT and other future protocols.
LCD Display
An 80-character (two 40-character lines) LCD display is located on the front panel to
provide extended features, status information, and troubleshooting indications.
Network Analyzer
To further assist with troubleshooting, the CNRACKX contains Crestron’s patent-
pending network analyzer to continuously the integrity of the Crestron network for
wiring faults and marginal system performance or other network errors. For more
