I need the pinouts for a nintendo wii headset (usb pinouts)


The USB interface is standardized. Knowing the pinouts isn't useful for creating your own headset, but here are the pinouts anyway:

We have two motorola CDM1250 two-way radio installed in the same room .Seem to be getting feedback in one unit when the other unit mic is pressed. it does not happen when the other unit mic is pressed....


You might check your antenna locations, connections, coax and cables. Feedback is sometimes cause by two or more transmitters being too close together (or bad coax/connectors). In the case of mobile radios, this would depend on the location of the external antennas. One radio may be more sensitive than the other, or a PL (private line) code is blocking the interference on the radio which appears to not have a problem. Feedback is caused by RF (radio frequency waves) in the environment. We suggest looking for the leak, and/or repositioning the antennas to be futher apart.

Best regards.

I need the pinout for the Avaya 2400 series telephone headset RJ-11 Jack.


I noticed that Avaya headset is different from the Avaya handset or any other standard headset: The outer two pins are switched.

Avaya-Headset-pinning is like this:
Look to the RJ11 and turn it until you see leads from top and from front, then from left to right you look at
1) mic 5V
2) speak
3) speak
4) mic gnd

RJ11 of Avaya-handset and any standard headset/handset from the supermarket:
1) mic gnd
2) speak
3) speak
4) mic 5V

Hope that helps.

Have new dx959 doesnt get out very far talking 100yrds or so use rdking 56 mic mic works fine on old radio pc 78 and gets out fine also are 959 radios ok or junk has good reception


The DX959 has an output power setting knob. It's located next to the channel selector and is labeled RF Power. Turned counterclockwise will reduce output power. Turned clockwise will increase output power. Your switch is probably turned all the way counterclockwise resulting in low transmit volume.
Also, make sure the wiring for the RK59 is correct for the Galaxy. Even though it's a 4 pin plug, the pinouts may be different for the Uniden and Galaxy radios. Do a Google search for mic pinouts for your two radios to check.

Converting a different brand of mic for a midland CB


This should be a typical Midland pinout. If you are using a generic 4 pin mic that is wired to cobra/Uniden, all you have to do is switch pin 1 & 2, then 3 & 4.

Not all mics are color coded the same with their wires.
