C2N-NPA8

 

If using a serial connection for communications between the control system and the 
C2N-NPA8, connect a straight through serial cable (Crestron cable number  
CNSP-587 or equivalent) from a compatible COM port on the control system to the 
COM port on the C2N-NPA8. All serial communication parameters between the 
control system and the C2N-NPA8 are automatically configured by the program 
stored on the control system. 

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. Use a straight through serial cable (Crestron cable number 
CNSP-587 or equivalent) with a DB9 male connector on one end and a DB9 female 
connector on the other. Most commercially available cables are acceptable. Refer to 
“COMPUTER” on page 5 for pinout details. 

NOTE:  

For laptops and other PCs without a built-in RS-232 port, Crestron 

recommends the use of PCMCIA cards, rather than USB-to-serial adapters. If a 
USB-to-serial adapter must be used, Crestron has tested the following devices with 
good results: 
 
 I/O 

Gear 

GUC232A 

 

Keyspan USA-19QW (Discontinued) 

 
Results may vary depending on the computer being used. Other models, even from 
the same manufacturer, may not yield the same results. 

Open the Crestron Viewport and click 

Setup | Communication Settings

 to display 

the “Port Settings” window. Then click 

RS-232

 as the connection type. 

The PC communication settings specified here should match the protocol that the 
C2N-NPA8 uses. The settings are as follows: 

• 

Port = COM 1 through COM 8. Select the correct COM port on the PC. 

• 

Baud rate = 115200 (You can set the PC and the control system to a 
different baud rate, by using the 

Functions | Set Baud Rate 

command. 

• 

Parity = None. 

• 

Number of data bits = 8. 

• 

Number of stop bits = 1. 

• 

Hardware handshaking (RTS/CTS) enabled. 

• 

Software handshaking (XON/XOFF) not enabled.
