CNXLIR Troubleshooting (continued)

TROUBLE POSSIBLE CAUSE(S) CORRECTIVE ACTION

CNXLIR is trying to

receive stray signals

(external noise such as

sunlight, etc.).

Make sure the receiving window is

positioned to avoid interference

from direct sunlight and high

frequency fluorescent light.

RDY LED or

SGNL LED

does not

illuminate or

goes out

immediately

in Learn

mode.

Applying signal before

CNXLIR is ready.

Wait for RDY LED before sending

a signal to learn.

OVRDR

LED

illuminates.

IR signal from remote is

too strong.

Increase the distance between the

IR source and the CNXLIR.

Computer connection

cable is wrong type.

Make sure the connection cable is

a RS-232, DB-9 “straight through”

cable with hardware handshaking

capability. Cable must include

RTS and CTS connections.

DEAL for

Windows

does not

communicat

e with the

CNXLIR.

Incorrect COM port.

Select the correct COM port

setting using the Preferences

window (Hardware Settings tab) of

the DEAL for Windows software.

Test

equipment

does not

respond to

IR signals

delivered by

CNXLIR.

Test signal is not being

received.

1. Reposition IR emitter and test

again.

2. Relearn and verify signal.

3. Test again.

Make sure the IR remote is held

steady on a firm surface while

transmitting IR codes to the

CNXLIR.

Tap the button on the IR remote

instead of holding the button when

transmitting to the CNXLIR.

If the frequency of the learned IR

remote is 455 kHz or more, check

that the sample rate in the DEAL for

Windows is not set to Low Sample

Rate (Edit | Preferences). If DEAL

for Windows is set to sample at the

low rate, set it to Medium Sample

Rate and relearn.

IR signal learned

incorrectly.

In DEAL for Windows, disable

“Signal Optimization” (Edit |

Preferences).

Test

equipment

does not

respond to

IR signals

delivered

from

CNXLIR.

Weak batteries

IR remote batteries may be weak.

Replace batteries in IR remote and

relearn.

IR code

does not

verify.

IR device could be a

“multi-code” remote.

Refer to the DEAL for Windows

help file that is included with DEAL

for Windows.
