Re: Setting Up a Model 100 for Packet Radio

Hello Guy,

The M100 works great for packet and it should be pretty easy to get
going depending on what kind of TNC you are using. I use a Kantronics
KPC9612 and an AEA PK12 with mine for mobile packet operation.

First your gonna need a serial cable to connect the TNC up to the
M100. A straight through cable will usually do the job. Take a look at
your TNC manual to see what it calls for. The next thing to do is go
into the TELCOM program where you should get a Telcom: prompt. This is
where you set up the serial port on the M100. Here's what I use for my
two TNCs

58N1E

That says run at 1200 BPS 8 Bits Parity None 1 stop bit and Xon/Xoff
flow control. A little on the cryptic side but it's all in the manual
for the M100 and you can get that on the club 100 web site here:

http://www.club100.org/library/libdoc.html

For my KPC9612 I run it at 19200bps so the settings are:
98N1E

After setting up the serial port type TERM and provided you have set
the serial port up to match your TNC you should be sitting at the TNC
prompt and ready for some packet!

Hope this helps - 73

Re: LCD fading ("power cont")

Is this just to recharge the nicad, or is there something more to it than
that?

Re: Setting Up a Model 100 for Packet Radio

Hello Guy:

The reply by Brian Brindle covers preliminaries for the "Terminal side" of
the Terminal/Node Controller (TNC).  That should allow "command mode" dialog
to commence between the "Terminal side" of the TNC and the terminal device,
which in this case is a Model 100 laptop.

The TAPR-2 command reference [ http://www.paccomm.com/cmdrefcrd.html ],
provided by PacComm, is a valuable online resource for conducting "command
mode" dialog.

A network of fixed-location packet nodes is fine thing.  But allowing
digipeation of frames by network nodes is where things get thorny -- 
consider this very carefully.

A way to quickly judge just how thorny the digipeation issue can become is
to do a search for every appearance of "DIGI" in the TAPR-2 command
reference provided by PacComm.  A search finds: 5 instances of "DIGI" within
specific TAPR-2 commands, and 33 instances of "DIGI" within descriptions of
sundry commands.

Remember two things: #1 digipeation within a commercial point-to-multipoint
network of fixed nodes is entirely different than digipeation within an
Amateur Radio network, and #2 digipeation is better as an emergency fallback
option that can be engaged during emergency operations than it is as an
established default that's ordinarily at play before an emergency arises.

Re: LCD fading ("power cont")

'Wet' electrolytic capacitors, i.e., non-tantalums may need to 'reformed'.
Electrolytic capacitors rely on wet chemistry to function. After long
periods of non-use the paste within them may lose the electrical properties
that make them good capacitors. These qualities *may* be restored by the
application of voltage..., the process is called 'forming'. Normally this
process is pretty immediate, but with low voltage devices, I suppose that it
might take a while. You have nothing to lose by trying.

Re: A Home Automation Project

I'd leave the Model 100 out of it - I suspect tests would show that those 
outside light units which pick up body heat would pick up flames also.

ISTR there is a spray foam that offers protection for an extended period. 
You coat the house and leave it on until the danger passes.

Still, water is better than nothing. FWIW, in New Zealand shingle roofs are 
totally banned - all roofs must be fire proof.
