Obtaining Communications
NOTE: In order for the CNRACKX-DP to be fail-safe operational, communication
must be obtained with both CNXCPUs. The following procedure must be performed
on the currently active processor, the processors must be electronically switched, and
the procedure repeated for the other processor. To switch processors from the
Viewport, select Diagnostics | Switch Processors (CNRACKX-DP). To switch
processors from the front panel default LCD display, press the DP button then CPU
and the CNRACKX-DP will reset and make the other CNXCPU active.

NOTE: If optional CNXENET+ Ethernet Expansion Cards are installed into the
CNXCPUs, communications can be obtained with the CNRACKX-DP over TCP/IP.
The CNXENET+ Operations & Installation Guide explains how to load the required
IP Table that contains the addresses of the Ethernet devices and set up the control
system for Ethernet communications. Refer to the CNXENET+ Operations &
Installation Guide (latest revision of Doc. 8153) for further information.

Before attempting to upload the program files into the CNRACKX-DP, it is
necessary to first establish communication between the CNRACKX-DP and a PC.
There are two ways of communicating with the CNRACKX-DP, either via the
COMPUTER port (RS-232 serial communications) or via Ethernet if optional
CNXENET+ Ethernet Expansion Cards are installed into the CNXCPUs. Prior to
completing the following steps, be sure the communication cable is properly
connected as described in
