The following sections define how one would upload a SIMPL Windows
program to the control system, or upgrade the firmware of the
QM-WMC. However, before attempting to upload or upgrade, it is
necessary to establish communications.
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
(Discontinued)
Results may vary depending on the computer being used. 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) or the respective Operations Guide for the control
system. These documents are available from the Downloads | Product
Manuals section of the Crestron website (
the figure below for a typical connection diagram when uploading files.
Note:
Use a standard DB9 male to female “straight-through” cable.
