Hi Tom,

For your last question,  There is only one low current (50 mA) output on the
board.  It is PGM1 I think.    I purchased the PC5208 (8 PGM low current
outputs).  I don't use PGM1 on the board but I could.  I wire the PGM port
directly into the an INPUT on PORT B of the HomeVision.  Then you run the
GROUND from the DSC to the HV ground on the PORT B block.  The two devices
MUST have the same ground.  That is it.  No use of Aux+ since you are simply
toggling the PGM high or low with reference to the shared ground.  Sending
Aux into PORT B could damage your HV.

Good luck with this.  Let me know how it goes or if you have any other
questions.

Could you e-mail me the doc from Craig on the security.  My address is
liberyc@prodigy.net so you don't have to send it to the list if it is big.

Thanks,

Kevin

    Kevin,

    Thanks, saved me from frying something I'm sure. I'll order some of the
Elk relays and set it up that way. One last question. For monitoring the
status there is a PGM1 and a Aux+ on the DSC.  What get's hooked to the PORT
B input #1 and what gets hooked to the ground. I assume that the Aux+ goes
to the PORT B #1 and the PGM1 goes to ground - is that right?

    BTW, Craig from HV sent me an interesting article he's writting on
security interfacing w/ HV. I'ts helping some but is very generic for my
purposes right now but once I understand the HV IO a little better I'm sure
I'll get good ideas from it. Right now I just want to get the basics down
with out cooking anything.

    Thanks again,

    Tom

        DON'T HOOK UP PORT A DIRECTLY TO A ZONE.

        I have a HV-PC and use PORT A for controlling the relay for the
keyswitch zone on the DSC.  PORT A can only DRIVE relays or CMOS circuits.
IT IS NOT A RELAY ITSELF.  Port C could be used to drive a relay also if you
specify it as an output.


        I use a relay for the keyswitch zone because you need to "complete
the circuit" for the zone.    I use ELK 924 SPDT Sensitive relays.  They are
really nice and have not failed me.  They require a separate 12V Power
Supply.  I also use these relays on my garage door openers.  Worthington
Distributors has them for about $9 each.  Craig also has application notes
on his website for quick easy setup.

        Using CAT5 wire from your HV-PC to the relay should work fine.


        Hope this helps,

        Kevin

            Kevin / Martin,

            Sounds great! I just got all of my HV IO ports run to  a wiring
closet & terminated. Now I'm trying to figure out how to make use of them. I
think I understand the DSC alarm status, simply connect one contact from the
low output PGM1 to input #1 PORT B and the other to the PORT B ground.

            However, I am confused about the ability to arm / disarm the
system, I thought I could simply hook up a connection from either PORT A or
PORT C to an unsed zone and define it as a keyswitch zone. But you both
speak of a relay being necessary to accomplish this. I assume therefore that
only PORT A is usable, but I'm still a little fuzzy about the hook up. I
thought that PORT A was a relay. But since you both discuss an external
relay ie. ELK / Prarie Digital I guess I'm wrong. Could one or both of you
please enlighten, me on this. Is there an external power source needed? If
so what kind and can any relay be used or would you recommend ELK / PD.

            Sorry for all the questions, but since I'm obviously confused I
don't want to hook up anything wrong and fry the HV or the DSC.

            Thanks,

            Tom

                Hello All,

                I have the DSC 832 (PC5010) and the intercom system(PC5928)
and the low current 8 output module (PC5208).

                I have a keyswitch zone which allows arming/disarming of the
system:  The HV output is directly connected to an ELK relay that closes for
3 seconds (just like what Martin Terry has ).  The relay is connected to one
of the DSC 832 zones to arm/disarm the system.  NOTE:  I had to use a EOL
resistor 5.6K ohms did the trick. See page 11 of PC5010 Installation manual.

                I have one of the DSC 832 low power outputs going directly
to a HV-PC input - this is programmed to tell me if the system is armed or
not.

                Intercom:
                I have three intercoms on the system right now.  I am using
the radio/aux input feature for ECS to speak to the house "works super!".  I
have the output of the sound card signal connected to the " " terminal and
the ground to ground - Only problem is that I get a low hiss on the intercom
stations - DOES ANYONE KNOW HOW TO FIX THIS?

                SR: I have trained MS SDK using the intercoms.  The first
time: with great results, the second: not so great.  Since then SDK has not
functioned properly (I have never had much luck with this).  I am determined
to eventually get it working though.  Another problem is that you can only
tap the microphone input for one of the intercom stations ( I Think ).  So I
am thinking that a microphone mixer will be needed at some point to combine
inputs.

                That is about it right now.  I love the DSC 832 so far. Good
Luck and keep in touch with your progress!
                General Question:  How do I wire up the zone -following
function?  Can I run the zone right into my HV-PC?

                Kevin

                    All,

                    I want to set up my HV-PC / ECS system to interface with
my security system (DSC Power 832). I want to run the HV ports to a wiring
closet so that I can home run wiring from there. My question is can I simply
run 4 pair cat 5 cable from the HV itself to a terminal strip in my wiring
closet and from there to the security system ect (I realize it won't be '
CAT 5' any more but I already got the wire)? Also, does each port require a
separate ground / common or can all be tied together.

                    Has any one out there tried this combination? I want to
use ECS to determine if the system is armed or not and arm it at the
appropriate times. I also want to have certain things happen depending on if
the system is armed / disarmed in the away / stay mode based upon the time
of day, turn on/off lights ect. I also would like it to do certain things
depending on who arms / disarms (wife / kids each have their own code). Last
but not least I want ECS to phone me in the event of alarm with seperate
messages for intruder / fire / CO ect.
                    I know its alot but what the hey, Christmas vacation is
coming up so I'll have a little time to play.

                    PS. I have the DSC 832 intercom system installed and
would like to pipe background xmas music / CID / ECS messages through the
system as well as use the built in mics for speech recognition. Any
thoughts?

                    Thanks,
                    Tom
