QM-RX
To add an IR device, drag the device from the Crestron, Project, or User IR
Database to the C2I-RX-IR1. The Crestron database contains hundreds of IR
driver files, covering most IR devices on the market today. The IR port requires
one IRP2 (infrared emitter probe) installed on each IR device. One end of the
emitter is installed on or near the IR sensor window of the controlled device
while the other end plugs into the port.
The ST-MB (master blaster) IR sprayer can "spray" IR signals 90 degrees. It
eliminates the need for IR probes and resistors, and can be positioned to reach
all devices. It is designed to handle multiple IR codes so that only one sprayer is
needed for many devices.
NOTE:
The C2I-RX-IR1 does not support simultaneous IR and RS-232
control. That is, an IR driver cannot be stacked on the port together with a
one-way serial driver. The control format must be of one type. Use only one
IR driver or one-way serial driver.
In addition, the IR port does not have negative voltage and thus may not provide
the full voltage range required by some RS-232 devices (although nearly all
RS-232 devices will operate properly).
Slot 4: C2I-RX-DI1
Slot 4: C2I-RX-DI1 provides one digital input port for connection of an external
sensor or other contact closure device.
Detail view of the Digital Input Card
The C2I-RX-DI1 provides one digital input port for connection of an external
sensor or other contact closure device.
The signal indicates a drop in voltage to less than 1.1 V. The output remains
high for as long as the voltage reads less than 1.1 V. The input voltage must
change by at least 0.3V in either direction to register a new logic state, which
prevents jitter.
An internal 2K ohm pull-up resistor forces the port to read 5.0V if there is no
external sensor connected.
•
High/1 = Voltage less than 1.1 V
•
Low/0 = Voltage more than 1.1 V or no device connected
Example Programming
An example program for the QM-RX is available from the “Example Program”
section of the Crestron website (http://www.crestron.com/exampleprograms).
