Re: GE Interlogix NX-8E NX-584 Zone transition message issues - Did I really find the fix?

A blast from the past¡­

Hi Mike,

Around 2008 I wrote my own module that could run in transition mode. I saw the specific case you mention during Disarm On Entry where the Disarm command took a while to get through. What I observed, on both the NX-8E and the NX-584, was that the device was sending a constant stream of messages (up to 8 per sec), a combination of zone, partition, and system status. I did not find a way to throttle it. I considered the behavior a defect in the device (not the first one related to the serial protocol), so I changed my command retry algorithm for this one command. I made the timeout shorter and added more retries. That got the command through within albeit not always as fast as a use might expect. In debug and test of this issue I never saw the device stop responding. It just appeared to be busy sending messages unnecessarily fast. If you see it stop responding for a period its likely due to waiting for an ack, and as you note you can¡¯t send it anything else when it expects an ack.

You solution finds a window in which you can get the disarm command in. Nice.

Best I can tell it is a board that other people say they try that implements this protocol as a separate board. I am also only using the NX-8E serial port for testing this, and do not use the 584.?

If your application only uses polling (no realtime zone transition notifications enabled ) or doesn¡¯t involve sending requests to the panel, you will not notice an issue.

The most prominent manifestation of this issue is in a home where the homeowner disarms the alarm and the disarm command takes several seconds to work because it is getting ignored by the panel as the panel comms freeze while trying to tell crestron about the zones the homeowner tripped when they walk in the house.

the solution of switching to ¡°polling¡± fixes it, at the expense of seconds of delays in finding out when zones trip, and cpu time on the processor to continuously ask NX about zone status. ?This solution will be for those who need the best of both worlds with this equipment?

Re: Any suggestion Swamp24x8 replacement with CrestronHome

 

The above suggestions are good, but not compatible with Crestron Home, as far as I know.? The only non-Crestron matrix that I have found to work with CH is AV pro edge.? They have a 12x12 AC-AEX-RC-HUB, that is ok (you may have to attenuate the sources).? They also have the AC-MAX-24 24x24 matrix, we have tested this in house but not deployed yet.? These do not have amps built in, I'm not aware of anything that works with CH that is one solution.?
Re: Any suggestion Swamp24x8 replacement with CrestronHome

 

My favorite non-Crestron multi-zone amp is the Autonomic M801e. It integrates very well with Crestron, is reasonably-priced, and sources connected to one amp can be streamed over the network to other amps.

Second favorite would be the AudioControl "Director" (M Series) models, or the 70-Volt CM models. I've integrated both in recent projects with good results.

Of course, if budget isn't an issue, the NAX is the way to go. The least-expensive solution would be to grab a SWAMP off Ebay. I thought the high demand to replace old units would drive the prices up, but they're still surprisingly cheap.

Re: Test Submission

 

It depends on their work load. I did mine early this summer and it came back really quickly. Just a few weeks.
On the previous exam it took them 60 days. I think you have no choice but to be patient and assume its going to be 90 days.

yeah, same issue.? ?Today was especially bad as I was working with a PRO4.? I have the same issue with MC4 in my office.

I submitted mine in early October, got told 60-90 days, and have not heard back yet.? A guy I know on the inside told me he'd be surprised if they got back to me before the end of the year, right now.

VS2008 debug error with 3-series

 

After selecting the splusmanagerapp.exe and pressing attach, I get the following message:

"Unable to attach to this process. Attach is not enabled for this process with this debug type."

This has worked a while ago, but not anymore.

Anyone experienced this? And how to solve this?

Test Submission

 

Hi All,

For those that submitted their Silver, Gold, etc tests in the past, how long did it take to hear back from the evaluators with any feedback? Just curious.

Thanks

Has anyone had any issues with debugger contently disconnecting all the time???
Re: Crestron CCD and Samsung BET-H Series Issue

 

Update: I was able to get it working.

I missed reading the part in that said "Don't rename the package file" so after changing the name back and changing the code in SIMPL, I was able to get connected and get the TVs to Power.

I'm using this driver from Crestron.

Hope this helps!

Re: GE Interlogix NX-8E NX-584 Zone transition message issues - Did I really find the fix?

 

I posted the source code I wrote up on GitHub and called it "NX-8E-ComFix"



Interested in feedback, accolades, whatever!? Hope this helps
Re: GE Interlogix NX-8E NX-584 Zone transition message issues - Did I really find the fix?

 

Excellent Idea... I tried it.? The NX just wasn't having it.? It wouldn't accept a command that was immediately preceded by a filler ACK message, except on a small percentage of occasions (whether it succeeds could be timing related).? But you and I will both agree that a software-only fix without the burden of sourcing additional hardware is going to be ideal.

I am doing something different that narrows the collision window as much as possible.? I am looking for the knife's edge (specifically, the start bit) of the incoming message from the NX, literally the first RS232 start bit of the first byte of an incoming message, 1/19200 of a second long (if it's 19200 baud, as mine is set to).? I'm using an interrupt handler to sense it, and making a decision to abort based on the start bit alone, without waiting for the serial UART to receive the whole byte.? The abort is cleanly defined within the protocol (achieved simply by sending the byte 0x7e to start a new message) and the NX takes it like a champ.
