CNRACKX-DP
CNX Dual Processor Modular Control System
The three 9-pin DB9 female connectors shown on the previous page, (one on the
front panel and one on each CNXCPU) are used when programming the
CNRACKX-DP with a personal computer (PC). A standard DB9 female (PC end) to
DB9 male (CNRACKX-DP end) straight-through serial cable (not supplied) is used
to communicate with any COMPUTER port. The ports are electrically connected and
are modem compatible. The null modem cable is not included.

On each CNXCPU, there are two parallel network connectors, 4-wire and modular.
The 4-wire male connector (standard Crestron network port labeled 24 Y Z G) is
used to provide regulated 24VDC power to the CNRACKX-DP via an external
power supply that is sold separately. The recommended power supply for the
CNRACKX-DP 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.
CAUTION:
The external power supply provides power to the CNRACKX-DP and
its expansion cards and is
NOT
designed to fulfil the power requirements of all
devices in a Cresnet system. Depending upon the load factor(s) of the devices, power
supplies and wiring that are independent of the CNRACKX-DP may be required.
Refer to
on page 9 for additional information.
NOTE:
Refer to the latest revision of the Cresnet Network Interconnect Drawing
(Doc. 5411) or Modular Cable Requirements (Doc. 5682) when making connections
to the port labeled CRESNET. These documents can be obtained from the
Downloads page (CABLES and MANUALS Libraries) of Crestron’s website
(
. Search for CRESNET.PDF or MODULAR.PDF, respectively.
