Crestron CNXLIR Infrared Learner

12 VDC 0.5 A

The DC power connector provides external power via the Crestron 500 mA

power pack, Crestron P/N PW-1205 or equivalent (1000 mA power pack for

international configurations, Crestron P/N PWI-1210 or equivalent).

COMPUTER / RS-232

The nine-pin female serial port connector communicates with a PC when

"learning" codes via a standard DB9 F-M “straight through” serial cable.

SIGNAL

The SIGNAL port is reserved for future use and is not supported at this time.

IR OUT

The 3.5mm connector attaches to the Crestron STIRP (Infrared IR Probe) and is

used to test learned drivers. The probe end of the STIRP is placed over a

device's IR window while the other end is plugged into the IR OUT port on the

CNXLIR.

CNXLIR Indicators

The front panel has six LED indicators. Refer to the illustration and descriptions

below.

CNXLIR

PWR (Power)

Indicates that power is supplied to the unit.

IR OUT

Indicates activity on the IR OUT port of the unit. This is a visual confirmation

that an IR signal is being sent from the CNXLIR.

RDY (Ready)

Indicates that the CNXLIR is waiting for an IR signal. When the CNXLIR

receives an IR signal, the RDY LED goes out.

SGNL (Signal)

Indicates that the CNXLIR is receiving the IR signal.

CMPLT (Complete)

Indicates that the processing or "learning" is complete.

OVRDRV (Overdrive)

Indicates that an IR signal is too strong. When the signal is too strong, the

CNXLIR does not accept the signal and the "learning" process for that particular

function must be restarted.
