control system to the IR receiver on the controlled device. Care must be taken to
ensure that the IR emitter on the IR probe is properly located next to the receiver.
Manufacturers do not normally publish the exact nature of the data that is being sent
via their IR remote controls. Therefore in order to generate the proper signal out of
the Crestron IR card, the remote must be learned through the use of a special device
called an IR Learner. The device, when attached to a PC and used in conjunction
with Crestron's IR learning software (DEAL for Windows), will generate a driver
file that can be inserted into your programs. Once the program is finished and loaded
into the control system, the control system's IR card can convert the information in
the driver file into the proper electrical signal.
Crestron IR Equipment
IR Probes (CNXIRP and STIRP)
The IR probe (CNXIRP or STIRP) is a very small, wired IR emitter that Crestron
developed to be installed externally over a device's IR window. The probe is wired
from the control system and emits IR signals directly into the device's IR window.
Since the IR Probe can be mounted externally on equipment, it eliminates the need to
open other manufacturer's equipment in order to rewire or alter the IR window. In
addition, by installing the probe directly on the device being controlled, the
interference caused by direct sunlight and high efficiency fluorescent lighting can be
eliminated.
IR Sprayer
The IR sprayer in an IR emitter that can "spray" IR signals 90 degrees. It eliminates
the need for the IR probe and can be positioned in a central location to reach all
devices. It is designed to handle several IR codes so only one sprayer is needed for
many devices.
IR Device Modules/Control Cards
IR device modules, such as the C2IR-8 or the IR ports built into some control
systems, provide control of IR or some serial controlled devices. The C2IR-8 and the
built in IR ports require the IR probe (CNXIRP) when using IR communication.
See Serial IR for information on using IR ports for serial communication.
IR Learner (CNXLIR)
Crestron Electronics CNXLIR is used to "learn" the codes (pulses of infrared light)
that a device's remote sends to control a piece of equipment. By learning these codes
programmers can create custom IR device drivers. DEAL for Windows software
allows programmers to create, modify, and test driver files. Programmers can then
store the learned .IR files in the User Database for use in their SIMPL Windows
programs.
