Crestron CNXENET+ 

CNX Enhanced Ethernet Expansion Card

To work with CNXENET+ web pages, communication must be established with the 
control system. To establish communication through the control system 
COMPUTER port, obtain a straight-through RS-232 cable that has a DB9 male 
connector on one end and a DB9 female connector on the other. Straight-through 
means that pin-1 on the male end is connected to pin-1 on the female end, etc. The 
male end plugs into the control system COMPUTER port. The female end plugs into 
the serial port of a PC. If the PC has a DB25 male connector, obtain a DB9 to DB25 
adapter (the adapter has a DB9 male and a DB25 female end). Thereafter, 
communications may be achieved by using the Crestron Viewport to directly connect 
to the IP address assigned to the control system. To establish Ethernet 
communication, refer to “Communicating With the Control System via Ethernet” on 
page 16. 

After establishing communication with the control system and verifying 
communication parameters, use the Viewport (from either SIMPL Windows or VT 
Pro-e) to transfer web pages designed with VT Pro-e or the e-Control SDK.  

1.  From Viewport, select File Transfer | Send Web Pages.  

 

NOTE:  When the CNXENET+ card receives web page files, it first initializes itself 
which deletes all of the files on the card. The Crestron Viewport provides 30 seconds 
before file transfer begins and transferring large web files may exceed this time. 
When transferring large web files, the card may produce an error of “Can Not 
Delete Files” or “Transfer Error” in the Viewport. If so, transfer large web files 
one at a time.
