  • Page 13: Hardware Hookup

    NOTE: For the C2N-NPA8 to function, power must be applied to a power or Cresnet connector on either NET A or NET B. The C2N-NPA8 will not function if 24VDC power is not applied to either NET A or NET B’s power connectors.
  • Page 14 Network Poll Accelerator Segments that are not in use or have devices that are not polled by a Crestron SIMPL Windows program are logically ‘disconnected’ from the other segments in operation. The LEDs for these segments are not illuminated. To properly configure a network using a C2N-NPA8, the network traffic should be balanced across the eight legs of the C2N-NPA8.
  • Page 15 Crestron C2N-NPA8 Configuration Example NOTE: 24 VDC power must be supplied to the C2N-NPA8 by the PWR connector on segment A or B. The control system must communicate with the poll accelerator via serial or Ethernet communications. Operations Guide – DOC. 6087A Network Poll Accelerator Network Poll Accelerator: C2N-NPA8 •...

    Supply. This power supply features eight power outputs, which can be used to control power to each of the eight segments on the C2N-NPA8. By wiring each power segment from the C2N-SPWS300 to a segment on the C2N-NPA8 (as shown...

  • Page 17: Communication Connections

    Although equipment damage is unlikely, Crestron does not recommend applying two power sources to the same segment. Communication Connections When using a PC for console operations on the C2N-NPA8, refer to “Establish a Serial Connection” on page 14. The C2N-NPA8 can also be connected to compatible control systems that are equipped with an Ethernet port.
  • Page 18 TCP/IP Communications Between a Control System and the C2N-NPA8 If the control system is to communicate with the C2N-NPA8 over TCP/IP, a serial connection must first be established to configure the C2N-NPA8 TCP/IP settings. Establish a Serial Connection Connect the COMPUTER port on the C2N-NPA8 to one of the COM ports (usually COM 1) on the PC.
  • Page 19 C2N-NPA8 for TCP/IP communications. NOTE: The terms used in the following steps are explained in detail in the Crestron e-Control Reference Guide (Doc. 6052). The latest version is available as a PDF on the Crestron website (www.crestron.com).
  • Page 20 TCP/IP communications between the C2N-NPA8 and the control system will be disabled while serial communication will be enabled. Once the IP settings have been defined in the IP tables of the C2N-NPA8 and the control system, the C2N-NPA8 can communicate with the control system using a TCP/IP connection.

  • Page 21: System Monitoring/Diagnostics With The C2N-Npa8

    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.
