RFID and Elk M1G

[Traditore]

Does anyone think it's possible to use something like this : http://cgi.ebay.ca/Mini-Wiegand26-Weatherp...=item3ca9f324d0 instead of the ELK-106055 UltraProx Wiegand Reader? Seems like a much cheaper (though less elegant) solution.

For that price, why not try it and report back? The M1KP manaual states that it is compatible with other 26-bit Wiegand devices.

An ELK-106055 External Prox Reader may be connected to the ELK-M1KP
Keypad instead of the optional ELK-M1PR Internal Mini Prox Reader. This
requires an ELK-WO35A Cable Assembly (purchased separately). Splice wires
as indicated, and plug cable into connector J2. NOTE: The M1KP is also
compatible with many other brands of 26 bit Wiegand compatible readers.

I guess you're right. I should just go ahead and try it. Of course, I'd have to find compatible fobs or cards for it.

 

[Traditore]

I finally found a little time to try it out and it works. I registered an access card and a fob and I can arm/disarm the system and open the garage door (with rules, of course).

I just don't know yet how to activate the buzzer and the green LED, even though I know which wire is which.

Hi,

If it is a standard Wiegand device, then connecting the LED or beeper wire to ground should activate them.

That reader looks strikingly familiar to an HID ProxPoint.

The beep wire should be yellow, the red LED wire should be Brown, and the Green LED wire should be orange. As mentioned above by Paul, grounding them will activate the device.

Some devices are programmable for 1 wire LED control or 2 wire LED control.

If you have one of the M1KP keypads from the first batch produced by Elk the brown wire is a switched negative capable of 50ma. You could use this output wired directly to the reader function you need to control.

I went with a slightly different model than the one I linked to in my first post. In my case, the beep/buzzer wire is indeed yellow and the blue wire turns on the green LED. Both activate when coupled (grounded) with the black wire.

How can I tell if I have one of the old keypads with the switched negative instead of the switched positive?

Page 1 of the M1KP PDF on Elk's website:

NOTE: The first batch of M1KP Keypads provided a switched
negative (pull to ground) output. Connect per diagram above.
These units have the letter "E" at the end of the ID number on
the lower back side of the board. EG: PC096E Boards with a
letter "F" or later provide the output as a switched positive.

 

[Traditore]

Mine is letter G. So switched positive, apparently.

Is there a way to find this out (if it's positive or negative) with a multimeter?

 

[gatchel]

I would say you are switched positive if the letter is G.

Can you provide a link to the model you used? What fob and access card? Anything else (other than what is covered in Elk's documentation) about this device we need to know to make this work?

Thanks . . . John

This is the one I finally ordered: http://cgi.ebay.ca/R70-Wiegand26-Waterproo...=item3a54fcf309

And I bought my cards and tokens from him too. Check out his store.

You connect the four necessary wires, you create your rules and you're all set.
