Establishing Communication with the Control
System
Before uploading a program to the control system or performing diagnostic
functions, you must connect the control system to the PC. This connection can be
serial or (if an optional Z-Bus card is installed) it can be TCP/IP.
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:
Belkin (large model) F5U103
I/O Gear GUC232A
Keyspan USA-19QW
Other models, even from the same manufacturer, may not yield the same results.

Serial Connection

Connect the COMPUTER port on the CNX-DVP4 to one of the COM ports (usually
COM 1) on the PC. Use a straight through RS-232 cable with a DB9 male connector
on one end and a DB9 female connector on the other. Most commercially available
cables are acceptable; they should have at least 5 pins for transmit, receive, ground,
and hardware handshaking.
Open the Crestron Viewport and click Setup | Communication Settings to display
the "Port Settings" window. Then click RS-232 as the connection type.
