Problems enroling m1xep

[newalarm]

Trying to setup up my m1g with m1xep.

I have the M1dbh connected to J1 on the lower right of the m1g panel. JP3 is NOT jumped (i think this is right??)

i have a m1kp plugged into J1 on the hub and J2 has the termination plug (rj45).

M1XEP is plugged into the m1g using the serial port cable. M1xep is on. ethernet cable connected back to my switch. yellow light solid, green light occasionally blinks.

When i try to enroll the m1xep on the keypad, it gives me an error message

kp addr 1
lost comm

I read that there needs to be a resitor on the m1kp, but kind find this anywhere on the wiring instructions. My termination jumper on the back of the m1kp is NOT terminated.

Finally, how are you supposed to connect once in ELKRP? I can't seem to find a connect to m1XEP or sim..

The panel also makes a clicking sound once in a while, sounds like a relay or something.

thanks for your help.

JP3 on the M1 would need to be jumpered. You have a single data bus. If you use a hub, no termination resistors need to be enabled at the KP's or expanders.

The easiest way to connect to the M1 via an XEP after enrollment would be via a crossover cable direct to a PC, via the default IP address the XEP is configured with, then make all your necessary changes in RP, then I'd start making changes on your network.

Even though you have DHCP, I generally prefer to allocate a single IP to be assigned to the XEP on the local network segment, then deal with the internet via DNS servers.

The clicking sound isn't specific enough of a description as to what is or may be going on. More detail would need to be known about the configuration, what is wired and what the KP or RP is showing going on.

Problem is I can't enrol the m1xep from the keypad. it gives me that 'comm' error noted above.

I will need to build a crossover cable, but the switch should work instead. We use it all the time so I don't think there is an issue with it.

JP3 on the M1 would need to be jumpered. You have a single data bus.

So with the data bus hub, you need to have JP3 Jumpered on the M1G panel? i could not find this in instructions.

The XEP will enroll via the keypad. It will not show up as a device. The lost comm on the KP is normal when the system is enrolling bus devices, then returns to normal. Assuming you have a single KP, then you would not need to address it, however any additional KP or subsequent expanders would need appropriate addresses.

The bus wiring and terminations are located on Pg. 12 of the manual I'm looking at.

What exactly is JP3 on the control? I am just trying to understand its purpose. I will try jumping it. The keypad was working (turning alarm on and off) without it jumped.

thanks.

It is a terminator jumper for the RS-485 bus. RS-485 is very particular and requires first and last terminations jumpered. Since the Elk can be used with and without databus hubs JP3's termination depends on specific wiring scenarios shown on page 12 of the Elk M1 installation manual.

BSR, for clarification, your post is somewhat confusing and I'm sure one that doesn't understand 485 would misread your post regarding first and last termination resistors.

In the case of the M1, you can run 2 separate 485 busses, each requiring a terminating (120 ohm) resistor to help with data reflections on the bus. The terminating resistor is installed at the last device on the bus, or in the case of 2 busses, 1 for each. The resistor(s) are enabled using jumpers or dipswitches. You would never have more than 2 terminating jumpers/resistors enabled for a standard bus.

If you have a single bus (or hub that isn't cascaded from one prior), then it's going to be terminated at the last open RJ45 in addition to J3, for a total of 2 terminations.

If you wired 2 hubs straight to the panel, J3 wouldn't be jumpered, since you terminate at each hub, again 2 total.

The only variation of this would be if you had a DBHR, which provides 8 individually terminated branches, and if really pushed, you can run 2 of them on an M1 and still maintain proper 485 termination as far as the panel is concerned. I doubt many will ever see 2 DBHR's installed on too many jobs, however in my area, there's a lot of legacy systems that didn't have enough conductors at the keypads or expanders, and I've become way too familiar with them.

So on the M1G, you have three data bus connections: J1, J2, and the 5 connectors above them? Only two of the three can be used?

I jumpered JP3 finally but did not notice much difference in system (though I do not have much connected and am just getting into programing). I now see the note about JP3 and terminating at "control" (just learning terminology too). I was confused by the term control and the note that said 'located under cover'; never found out what that was about.

I also FINALLY got connected to the XEP. I did not see at first the button for starting set up at the bottom of the window that takes you through the step by step instructions.

Thanks for all your help everyone; REALLY appreciate everyone's patience and help!
