CNX Control Processor Card:
CNXCPU
Description
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
Cresnet network and the expansion cards
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
described on the next page.

CNXCPU Ports
The CNXCPU contains a COMPUTER port, two CRESNET connectors, and a DPA
slot. When the optional Ethernet Expansion Card is installed, the LAN/DPA port on
the faceplate is available. The ports are described below:

This 9-pin DB9 female RS-232 connector is used when programming the CNXCPU
with a PC. A standard DB9 male (attached to the CNXCPU) to DB9 female
(attached to the PC) straight-through serial cable (not supplied) is used to
communicate with the port. Additionally, there is a DB9 female connector on the
front panel of the control system and both ports are electrically connected. The ports
are modem compatible but the null modem cable is not included.

This 4-wire male connector (typical Crestron network port labeled 24 Y Z G) is used
to provide 24VDC power via an external power supply that is sold separately.
Crestron recommends specific power supplies for its network devices. The
recommended power supply for the CNXCPU is Crestron part number CNPWS-75
and for international configurations, part number CNPWSI-75.
The 6-pin RJ-type modular connector is used for expansion to (or from) SmarTouch
and Cresnet peripherals.
NOTE: If using the modular connector, review the latest revision of the Crestron
Network Modular Cable Requirements (Doc. 5682). Most 6-conductor telephone
cables are wired in a crisscross fashion and are not compatible with Crestron
equipment.

CNXCPU Indicators
The CNXCPU contains two LED indicators located on the faceplate. The indicators
are described below:

This green LED illuminates when the CNXCPU is connected to and receives power
from the CNPWS-75 External Power Supply (sold separately)
NET
This yellow LED illuminates when the CNXCPU is processing or communicating
with system hardware. Examples are button presses at a Touchpanel, data being sent
through the computer port, or a permanent memory image being created.

Leading Specifications
The table below provides a summary of leading specifications for the CNXCPU.
Dimensions are approximations rounded to the nearest hundredth unit.
Leading Specifications of the CNXCPU
SPECIFICATION
DETAILS
Power Requirements 24VDC from the CNPWS-75 External
Power Supply (not provided), load factor
of 4 Watts. (With optional Ethernet
Expansion Card installed, load factor is 8
Watts.) *
Connector 26-pin DPA connector for optional
Ethernet Expansion Card.

Depth: 6.65 in (16.89 cm)
Weight: 5.30 oz (0.15 kg)
*CAUTION: The total load factor of the CNXCPU depends upon the
components of the control system. Add the power requirements of the CNXCPU
plus the control system requirements plus the combined requirements of the
remaining expansion cards. Do not exceed 75 watts for total load factor.
As of the date of manufacture, this unit has been tested and found to comply with
specifications for CE marking.
NOTE: This device complies with part 15 of the FCC rules. Operation is subject to
the following two conditions: (1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may
cause undesired operation.
Setup
Installation or Replacement
