Hi,

I have been trying to install the ad2pi on my DSC 2550 with little success. I am able to telnet into the device and it gives me this output:

!Reading configuration.
!UART init.
!
!>Ademco/DSC Mode A/D (D) :>
!>Keypad Partition (11) :>
!>
!CONFIG>MODE=D&CONFIGBITS=1116&ADDRESS=11&LRR=N&COM=N&EXP=NNNNN&REL=NNNN&MASK=ffffffff&DEDUPLICATE=N
!Reading configuration.
!UART init.
!VER:ffffffff,V2.2a.8.6,TX;RX;SM;VZ;RF;ZX;RE;AU;3X;CG;DD;MF;L2;KE;MK;CB;DS;ER;CR

It says keypad partition 11 but DSC only allows up to 8? I have two working physical keypads and I have disconnected one and attempted to use that assigned number but no success.

When setting up the device through the web interface I get the the 'key communication (send)' step and it either times out or presents an error saying check the connection etc. (I have wired as per instructions Y-G G-Y).

Any assistance would be greatly appreciated.

Cheers

Keypad Partition on DSC setup is not documented well yet since the new firmware changes

It is structured as such: <partition><slot> so "11" would be partition 1 slot 1 by default - sorry for the confusion

If you could connect to the ser2sock port or the device directly and try to send keys to the panel it would be helpful - if it is not successful, please email a debug dump with configuration settings to ad2usb@support.nutech.com

@48 to enable debug
@00 to disable

Just wanted to mention that your CONFIGBITS setting looks very strange. The default is ff04. I can't tell what your MASK setting is since it got cut off, so you might want to confirm that that isn't something strange as well. It's default is ffffffff.

Are you using our image for the Raspberry Pi? If not, you should make sure that you've fully disabled the serial console. That's usually the #1 thing that causes strange configuration settings like this.

Hi,

Thanks for the help. I am using the your pre-built image on a raspberry pi 2. I'm actually on to my second rpi2 and still unable to set up the device (in case it was pi hardware). I get a check mark on 'opening device' but either test timed out or check connection on the other headings. Here is my current telnet output:

Code: Select all

I'm at a bit of a loss as to where to go next. I have disconnected both of my physical keypads. I also have a pi3 for testing which I could try next. I also came across config bits ff00 if that means anything. I have access to the programmers guide for the DSC 2550 but I can't seem to find the part that will allow me to add extra keypads.

Appreciate the help.

Cheers

I started over and then got this output:

Is there a common theme? I can't tell.

Thanks

Please make sure your wiring is like this diagram for DSC:

Also note that all 4 wires need to be attached

Was just made aware that there is a service to disable on the pi2 as well - the hciuart service

Hi Kevin,

Thanks for the response. I have disabled the hciuart service and I have all wires connected. Can you please confirm what the best GPIO pins to use on the pi 2 are? I will also attempt to use the existing wiring from my physical keypads to rule out any wiring issues as these are usable if connected.

I am also experiencing the steady green LED flashing on the device which is the boot loader?

Thanks

Please email support so we can get you in touch with engineering for help with debugging

Thanks. i'm beginning to think that my DSC 2550 is incompatible. I may upgrade my board. In the meantime I'll email support and see if we can't crack this nut.

Cheers
