Anyone using MDC1200 for control?

Hi Everyone,
New to the group and Asterisk; got my first node online today. I know there are libraries available from Matthew Kaufman for MDC1200 decoding, but haven't ventured into the code just yet. Does anyone have examples of what works and how difficult it was? I want to simply send an MDC ID into Asterisk to control my links/macros versus DTMF.

Thanks!

Well, it could very easily. Im game.. (be sure you
pronounce that right) :-). What kind of MDC-1200
message type are you intending use (excuse the
possibility of this being a dumb question, but
the only thing Im familiar with MDC-1200 for is
UnitID).

Thanks Jim for the reply and interest. Basically I just want to send/decode the Unit ID that will be used as a control function (i.e. macro to connect up to site "X"), activity timer (link transmit authorization) or repeater access control. I like MDC since its a fixed-length packet, has error-correction built-in and once programmed in to a radio mode doesn't require using a DTMF mic while mobile.

okay, What I will do is have a list of "Unit-ID"'s that
can correspond to DTMF macros. In other words, you
could make unit ID 1234 be the same as pressing *32000
or something like that.

Is that pretty much what you had in mind??

Wouldn't it be better to use mdc status messages for control? The unit
id is sent every transmission.
You really wouldn't want a dtmf macro activated every time a unit
transmits.. that could be real bad if you slip on the ptt.
I can see it would be pretty easily to generate a couple commands by
accident. I think MDC status messages are more
up that alley.

My MDC-1200 biggest wish is an "MDC squelch" that will compare the
unit-ID to a list, if in the list allow the audio to repeat.

A local ham repeater (fishfar) only allows access based on a known
list of Unit IDs.

My concept would be status-1 to enable the repeater, status-2 disable,
status-3 reboot the server, status-4 enable mdc-squech,
status-5 enable pl squelch, status-6 send "ffff" all call. Something
like that....

It would be really cool if we could also have the ability to generate
MDC messages. a command like rpt mdc 2090 ffff which would generate
an ffff all call on node 2090 would be really appreciated.

Being able to watch the output of the decoder into a log would help
find what codes are being seen.

In the mean time, I recorded my ht sending the "all call" and play the
wav file back. It does activate all the radios each time it's sent.

The new version of app_rpt.c which will be posted on SVN
this evening contains new code (experimental at this point)
which allows you to put a '[mdcmacro]' stanza in your rpt.conf file
where the entries under it are UnitID=DTMF Tones To RUN

So, like:

[mdcmacro]
d00d=*32000

If you have id d00d, it logs into hub node 2000.

If you send the same ID over and over again, it ignores
subsequent duplicates.

If someone would find me a full copy of the MDC-1200 command
set, I sure would appreciate it.

Great! I never expected this so quickly. I'll grab a copy, compile and start testing. I'll do my part and try to find online documentation about the data layout for MDC.

You really wouldn't want a dtmf macro activated every time a unit
transmits.. that could be real bad if you slip on the ptt.
I can see it would be pretty easily to generate a couple commands by
accident. I think MDC status messages are more
up that alley.

My MDC-1200 biggest wish is an "MDC squelch" that will compare the
unit-ID to a list, if in the list allow the audio to repeat.

A local ham repeater (fishfar) only allows access based on a known
list of Unit IDs.

My concept would be status-1 to enable the repeater, status-2 disable,
status-3 reboot the server, status-4 enable mdc-squech,
status-5 enable pl squelch, status-6 send "ffff" all call. Something
like that....

It would be really cool if we could also have the ability to generate
MDC messages. a command like rpt mdc 2090 ffff which would generate
an ffff all call on node 2090 would be really appreciated.

Being able to watch the output of the decoder into a log would help
find what codes are being seen.

In the mean time, I recorded my ht sending the "all call" and play the
wav file back. It does activate all the radios each time it's sent.

Is that pretty much what you had in mind??

Thanks Jim for the reply and interest. Basically I just want to
send/decode the Unit ID that will be used as a control function (i.e.
macro to connect up to site "X"), activity timer (link transmit
authorization) or repeater access control. I like MDC since its a
fixed-length packet, has error-correction built-in and once programmed
in to a radio mode doesn't require using a DTMF mic while mobile.

Hi Everyone,
New to the group and Asterisk; got my first node online today. I know
there are libraries available from Matthew Kaufman for MDC1200 decoding,
but haven't ventured into the code just yet. Does anyone have examples
of what works and how difficult it was? I want to simply send an MDC ID
into Asterisk to control my links/macros versus DTMF.

Thanks!
Tony, KT9AC

Yes, it makes some output when it happily decodes a unit id

For those wanting extra functionality for "buttons" or whatever
it is your radios are equipped with. If someone could give me
a recording (of the receive input of a receiver listening
to your transmiter) of the output your transmitter as you
press the buttons you are interested in, and then tell me what
you pressed in what order, I could use that recording to do
what I need to do. Probably the best way to accomplish the recording
is to use the URI as a regular sound device (like on a windows machine
or Linux) and use a standard sound recorder program or editor
(like audacity) to make the recording.

Thanks!!

So how can you tell if the MDC is decoding? Is there a debug statement?

Great! I never expected this so quickly. I'll grab a copy, compile and
start testing. I'll do my part and try to find online documentation
about the data layout for MDC.

The new version of app_rpt.c which will be posted on SVN
this evening contains new code (experimental at this point)
which allows you to put a '[mdcmacro]' stanza in your rpt.conf file
where the entries under it are UnitID=DTMF Tones To RUN

So, like:

[mdcmacro]
d00d=*32000

If you have id d00d, it logs into hub node 2000.

If you send the same ID over and over again, it ignores
subsequent duplicates.

If someone would find me a full copy of the MDC-1200 command
set, I sure would appreciate it.

Wouldn't it be better to use mdc status messages for control? The unit
id is sent every transmission.

YES! This is working!!!!! I can't thank you enough for the effort. Now I can program up my radios to control the links remotely.

The console does what its supposed to, and the mdcmacro works 100% according to it.

I think this should be advertised as a major feature of Asterisk/Allstar.

Here is my output to confirm:

[mdcmacro]

a555 = *81

MDC info:

Here is a decoded direct page from 0684 to 1293
Got MDC-1200 (double-length) packet on node 2090:
op: 35, arg: 89, UnitID: 1293
ex1: 80, ex2: 15, ex3: 06, ex4: 84
That is an astro saber calling another astro saber.

Also:
I used 889=cop,60,C,0377,0684,8015
sent a *889 and the repeater belched out a turkey gobble.
0684's radio responded with the alert beep... which is the desired response.

Yeah......
