CNX Dual Processor Modular Control System Crestron CNRACKX-DP Physical Description The CNRACKX-DP is housed in a black enclosure with silk-screened labels on the front panel. On the front panel is a single RS-232 computer port, system status lightemitting diodes (LEDs), two reset buttons, a reverse LCD display with menu function and selection buttons, and a row of slot status LED indicators. The rear panel provides 13 open CNX expansion card slots and the two CNXCPUs.
Crestron 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.
CNX Dual Processor Modular Control System Crestron CNRACKX-DP CNRACKX-DP System Status Indicators There are 22 LED indicators on the front panel of the CNRACKX-DP. Four other LEDs are located on the rear of the CNXCPUs: PWR These LEDs (one on the front panel and one on each CNXCPU) illuminate when the CNRACKX-DP receives power from the CNPWS-75 External Power Supply (sold separately).
Crestron CNRACKX-DP CNX Dual Processor Modular Control System CNRACKX-DP LCD Display The front panel of the CNRACKX-DP incorporates a reverse mode (yellow on black) LCD display, shown below.
