Communication Settings
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.
The procedure in this section provides details for RS-232 communication between
the PC and the control system. If TCP/IP communication is preferred, consult the
latest version of the Crestron e-Control Reference Guide (Doc. 6052) of the
respective Operations Guide for the control system. These documents are available
from the Downloads | Product Manuals section of the Crestron website
(www.crestron.com). Refer to the following figure for a typical connection diagram
when uploading files.
NOTE: Use a standard DB9 male to female “straight-through” cable.
