Either get another 3 pin miniature jack and change wires per Brian's information or just cut the jack off and connect the three wires directly to the I/O Linc screw terminals.

Nice job!

That is how my little tester was assembled.

Nothing more than a 1/8" stereo jack mounted on a small scrap enclosure.

With three wires soldered to it. Then I used the three wires screwed in to the I/OLincs terminal block.

 

Radio Shack even makes an 1/8" In Line Stereo Female Jack. 274-274 set of two. On mine copper tab is Tip and Silver tab is Ring.

You could solder wires to one. Then make sure the tip connected to Sensor and the ring to +5.

 

If you decide to just cut the plug off. The Red in the cable is sensor and the White was the +5V.

 

If possible I would make an adapter and not cut the plug Off. That way you could still return it if needed. As I was also not impressed with the way the Input Voltage was handled.

Great write up Brian,

Thanks for your attention to detail and for sharing.

[OmegaQuest]

That worked Great!

 

I had an old Stereo female jack so I just cut that and wired it to the IOLinc terminals (red to S, white to +5, copper to Ground)!

 

Thanks!

Glad it worked for you.

You may want to connect a diode in series with the Black/White Input wire. Band end to the Black/White wire. If your input is AC. I don't like putting too much reverse voltage on the OptoCouplers input.

A 1N4002 or 1N4003 would be a high enough reverse blocking voltage.

[OmegaQuest]

ok, so put a 1N4002 on the end of the input positive wire and hook the other end of the 1N4002 to the doorbell transformer correct?

[Brian H]

Yes just disconnect the transformer from the Black/White wire and connect the 1N4002 band end to the Black/white wire and the other side of the diode where the wire was originally connected.
