Communication Settings - Crestron QM-TX Operation Manual

Crestron QM-TX
Operations Guide – DOC. 6334
The following sections define how one would upload a SIMPL Windows
program to the control system and upgrade the firmware of the QM-TX.
However, before attempting to upgrade or upload, 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 (discontinued)
Keyspan USA-19QW (discontinued)
Other models, even from the same manufacturer, may not yield the same results.
NOTE: Even with these recommended models, results may vary on the
computer being used.
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 Crestron website. Refer to the following figure for a typical
connection diagram when uploading files.
Typical Connection Diagram when Uploading
NOTE: Use a standard DB9 "Null-Modem" RS-232 cable when communicating
with a QuickMedia control processor. Use a straight through cable when
communicating with a 2-Series control processor.
Serial Connection
1. Ensure that all devices are connected to the control processor and the
control processor is connected via serial cable to the PC.
