    M1 KP2 Wiegand Interface Problem

    I purchased a simple W26 card reader/keyboard, hooked it up to the KP2, and it works great for programming, arming/disarming and access control.  I checked the idle voltage of this reader's D0/D1 outputs to GND, and it's only 4.2V, so that rules out a low output voltage issue with my original...

    M1 KP2 Wiegand Interface Problem

    The length of my wires to the reader is 18-24 inches.  I did have a problem using CAT5 for V+, GND, D0 and D1, but replaced with some 24ga. sollid coper wires, and all worked well with the M1KP.   The D0 and D1 voltage I was referring to is when the reader is idle.  I've Googled other...

    M1 KP2 Wiegand Interface Problem

      Checked the voltage at KP2 input, 13.6V, same at reader input.  Checked voltage at each of D0 and D1, 4.4V to ground each.

    M1 KP2 Wiegand Interface Problem

    For testing, I used the connectors from a motherboard-to-front panel connector (the black slip on connectors for HDD, Reset, Power, etc.).  I removed the crimped copper connector/wire combination from the black plastic housing.  The connector is a small copper conductor that wraps around the pin...

    M1 KP2 Wiegand Interface Problem

      I also thought it odd that I was originally unable to get the KP to receive wiegand signals from the reader using CAT5e 24ga. stranded wire.  However, when I replaced the CAT5e with the 24ga solid conductor cable, I've had no problem since.  I really didn't think it would take such substantial...

    M1 KP2 Wiegand Interface Problem

      Actually, I got tired of connecting and disconnecting the 2 different wiring harnesses when switching out the KP and KP2.  When I reinstalled the KP yesterday after trying the replacement KP2, I left the power leads to the reader connected to the V+ and GND wiring on the data bus, and just...

    M1 KP2 Wiegand Interface Problem

    Thanks for the reply, DELInstallations.  I'll check the voltage at the reader when I get back home.  I don't know if voltage is the problem, though, since the reader continues to make all of its normal beeps, noises and LED indications (accept/reject/onboard relay closure, etc.) regardless of...

    M1 KP2 Wiegand Interface Problem

    I have a fingerprint/prox card reader I purchased through a local supplier, that works great with the Elk M1KP.  I've been using this reader for over 2 months with the ElkM1 for access control.  It has not missed one valid fingerprint access or card access.  However, I'm having problems getting...
