Connecting the C2N-NPA8 to the Control System via Ethernet
To enable TCP/IP communication, use CAT5 straight through cables with 8-pin
RJ45 connectors to connect the LAN port on the C2N-NPA8 and the LAN port on
the control system to an Ethernet hub. Alternatively, you can use a CAT5 crossover
cable to connect the LAN port on the control system directly to the LAN port on the
C2N-NPA8 without using a hub. The following figure illustrates pinouts for straight
through and crossover RJ45 cables. Pins 4, 5, 7, and 8 are not used.
RJ45 Pinouts
Once the cable connections are made, verify communications by opening the
Crestron Viewport and clicking
Setup | Communication Settings on the menu to
display the “Port Settings” window. Select TCP/IP as the connection type and enter
the IP address of the C2N-NPA8. Click OK to connect to the C2N-NPA8 over
TCP/IP.
“Port Settings” Window
To verify communication, click Diagnostics | Establish Communications (Find
Rack). This should display a window that gives the IP address and port number.
If communications cannot be established between the C2N-NPA8 and a control
system, refer to “Troubleshooting Communications” on page 28.
System Monitoring/Diagnostics with the C2N-NPA8
A C2N-NPA8 in a Cresnet system provides improved troubleshooting abilities for
monitoring Cresnet devices. A common problem in building a system is the use of
devices with identical Cresnet IDs. In a system without a C2N-NPA8, Cresnet IDs
that are duplicated are not reported by the system when using the
REPORTCRESNET command in Viewport. A system with a C2N-NPA8
recognizes the existence of a duplicated Cresnet ID if the devices are on different
