Functional Description
The CNX Control Processor Card, CNXCPU,
CNXCPU Physical View
is the central processor unit of the CNX Modular
Control System. The CNXCPU performs the
execution of the SIMPL Windows program and
SIMPL+ programs as well as managing the

installed in the control system. The CNXCPU
requires an external power supply, CNPWS-75
(sold separately).
The CNXCPU features Crestron’s exclusive
DPA (Direct Processor Access) slot for
Ethernet/LAN expansion of the control network.
This slot provides high-speed access to the
processor, allowing high-bandwidth network
connections. The DPA permits 10BaseT and is
ready to support Firewire, ATM, 100BaseT and
other future protocols.
Physical Description
The CNXCPU, shown at the right, is a circuit
board fastened to an aluminum faceplate. The
faceplate contains one computer port, two
Cresnet connectors, and two LED indicators.
The circuit board (not shown) contains the DPA
slot that is used by the optional Ethernet
Expansion Card. The LAN/DPA port on the
faceplate is available when that card is installed.
The ports, connectors and indicators are
