 Posted: Tue Oct 28, 2014 11:56 pm Post subject: Infrared receiver module carrier frequencies |
 |
|
From Sharp GP1U58X and Vishay datasheets, I have identified infrared receiver modules with the following carrier frequencies (in kHz) with a corresponding protocol:
30.3 (Grundig)
32.75/33 (Mitsubishi and certain RECS80 and Thomson variants)
35 (Emerson and older Panasonic)
36 (Philips RC-5/RC-6 and variants thereof)
36.7 (Kaseikyo, its related counterparts and its popular Panasonic counterpart)
38 (Most common, including NEC)
39 (Electrohome)
40 (Sony, Pioneer and Zenith)
41.7 (Certain Philips and NEC variants
48 (unknown)
56.7 (RCA/Thomson)
455 (B&O)
Do you know of any infrared modules which have other rated carrier frequencies? If so, please mention your source.

Install IRScrutinizer. Go to the Generate tab and select each protocol. The first argument in the IRP is the frequency. That will give you every protocol we've ever seen, about 140 of them.

Rob's B&O protocol is 400 kHz, not 455. Not sure which is correct. |

I wrote a small Java program using the API of IrpMaster (which is the engine of IrScrutinizer) for collecting this information from IrpMaster.ini. Program:
| Code: | package getfrequencies;
import java.util.ArrayList;
import java.util.Collections;
import java.util.HashMap;
import java.util.Set;
import org.harctoolbox.IrpMaster.IrpMaster;
public class GetFrequencies {
public static void main(String[] args) {
HashMap<Double, ArrayList<String>> dict = new HashMap<>();
try {
IrpMaster irpMaster = new IrpMaster("IrpProtocols.ini");
Set<String> names = irpMaster.getNames();
for (String name : names) {
double freq = irpMaster.newProtocol(name).getFrequency();
if (dict.containsKey(freq)) {
ArrayList<String> al = dict.get(freq);
al.add(name);
} else {
ArrayList<String> al = new ArrayList<>();
al.add(name);
dict.put(freq, al);
}
}
ArrayList<Double> sorted = new ArrayList(dict.keySet());
Collections.sort(sorted);
for (Double f : sorted) {
System.out.print(f + ":\t");
for (String prot : dict.get(f))
System.out.print(" " + prot);
System.out.println();
}
} catch (Exception ex) {
// Sloppy error handling is ok in a program like this
ex.printStackTrace();
}
}
}

Update: Certain Pioneer Laserdisc players use an infrared protocol with a 48kHz carrier.

Probably the pr-8210 top-loader. I know it didn't respond to the laserdisc commands on my vsx-5000 oem remote in the mid-80's.
