    M1KPAS beeping and quirky

    Success!   Going from device to device was the only way that this was going to be found.  One of the wires had broken off at the B connector making it intermittent.  The only reason I found it is that I pulled out each and every set of wires to map it and one wire stayed behind.   I've since...

    M1KPAS beeping and quirky

    Sorry - I had forgotten what it was - I installed it years ago.  I was going by the pic on the website.  I went down to look and it's a P624   I'm assuming that what you're drawing there are two home runs coming off branch 4 on the DBHR.  In that case you're mostly right given what I had...

    M1KPAS beeping and quirky

    OK - finally some time to go through this.   So I'm actually using a DBHR that has 5 runs on it.  There are numerous expanders, keypads, and RF interfaces along the various runs and it's quite the ordeal to sort through all of what's there.   Since most of the runs seem to be trouble free I'm...

    M1KPAS beeping and quirky

    I'm hoping someone can point me at a solution to this before I order a replacement that I may not need.   I have an M1G  system that sprawls over a fairly large area.  The last area has an M1KPAS that is used for access control.  There are 6 keypads in the system daisychained to a final length...

    It seems sometimes you just have to suck it up, take it all apart, and put it back together bit by bit till it breaks.  It's just so disheartening having to do that.   Thanks again!

    Thanks for the suggestions.   It's finally - after possibly months of things not-being-quite-right and frustration - acting as it *should*.   I moved the second run from branch 1 to branch 4 as you suggested and adjusted the termination appropriately Them I renumbered the keypads starting from...

    I recently went through my Elk system with a fine tooth comb to verify termination etc.  I've got a problem that I've isolated to one branch but can't figure out where the problem is   I have an M1G with an M1DBHR board to allow me additional runs   I have 8 keypads, 3 expanders etc. but I'll...

    Good thought.  I'll try that out.   In truth I'm just being finicky.  My keypads 'were' numbered 1 through 8 but are now 1,2,3,5,7,8,9,11.  It doesn't really make a whiff of difference - I could just leave it alone as it's working fine.   Thanks.   mark

    Elk driving me nuts

    So an update...   I disconnected the last two devices (an M1KPAS and an M1XRFEG) from the daisy chain that was causing trouble and terminated the chain at the preceding M1KPAS.  That change immediately brought the resistance across the data lines on that bus to 65ohms.  It's been 24hrs now and...

    Thanks - from that post it seems like my error count is reasonable.  My last post was about an hour ago and the error count was 64.  It's now 94 - so 1 every 2 minutes.  Seems like a lot to me but within what Spanky was happy with (hard to type Spanky in a sentence lol)   My cable is cat5 but...

    Thanks.   What do you mean by a 'bad connection'?  As in not firmly connected to one of the devices on the bus?  I just went down and checked to confirm there is, indeed, a terminating resistor at the end of the line on bus 4.  Perhaps what I should do is go down tomorrow and break the daisy...

      Thanks - that's a handy bit of information.  I put the resistances I measured in my reply to the previous post.  They're all in the +- 10 ohm range except the troublesome one which is 85 or so ohms.  That run is quite long - 350/400 ft.  I'm figuring that's why the resistance is a bit higher...

    Elk driving me nuts

      I have an M1DBHR   the first bus has 2 runs attached - one leads to a keypad that's terminated.  The other goes to my garage passing through an unterminated M1XIN and finishing at an M1KPAS that is terminated.  The jumper is off for this bus.  Resistance across a/b is 65 ohms   bus 2 has 2...

    I just went out and finished doubling up the data wires just for a 'suspenders and a belt' solution.   Ground is tied together all the way through from the M1 all the way down to the last device.  The P112 ground ties in to that along the way.  +12 from the M1 feeds 3 channels on the M1DBHR. ...

    Elk driving me nuts

    The data run from the M1 is probably betweejn 300 to 400ft running over cat5. I didn't intend to go that far originally.   There is a P112 about halfway that supplies 2 M1XRFEG's, and 4 M1KPAS's.   When I realized how long this was going to end up I doubled up the wires in the Cat5 to decrease...
