Crestron c2enet-1 c2enet-2 User Manual

Crestron C2ENET-1/-2 

2-Series Ethernet Interface Expansion Cards 

The following instructions assume that the C2ENET-1/-2 is installed, Viewport is 
open on the PC, and the control system is powered up. 

NOTE:  If the PC has a DB25 male connector, obtain a DB9 to DB25 adapter (the 
adapter has a DB9 male end and a DB25 female end).  

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: 
 
 

Belkin (large model) F5U103 

 

Belkin (small model) F5U409 

 

I/O Gear GUC232A (discontinued) 

 

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. 

1.  Use the appropriate cable to connect the RS 232 COMPUTER port of the 

control system and the serial port of the PC. 

NOTE:  It is assumed that your PC is communicating with the control system and 
the appropriate update file has been loaded.  

2.  Obtain appropriate control system static IP and router addresses from 

the/your network administrator.  

NOTE:  The next three steps have you verify that the static IP address is not being 
used by another device.  

3.  On the PC, select Start | Run from the Taskbar to open the “Run” window. 

4. Type 

command in the Open field and click OK. A DOS window appears.  

5.  At the prompt, type PING and the IP number. Press Enter. 

Example: PING 192.168.1.102  

NOTE: Make sure you put a space between PING and the IP number. 

NOTE: If the system shows a “Request timed out”, go to step 6. If the system shows 
a “Reply from” with a time, the IP number is already in use. Obtain another IP 
number and repeat step 5.  

6.  Open the Crestron Viewport and select Functions | Set Control System IP 

Information from the main menu. The “Ethernet Configuration” window 
opens (refer to following graphics).
