                         PacLink Post Office Configuration

                                                    Enter your
                                                    callsign, and
                                                    choose a
                                                    password. You
                                                    can also select
                                                    to allow other
                                                    LAN clients
                                                    access to the
                                                    Post Office.
                                                    Click Update



Paclink install places two icons on
your desktop – the AGW and the
Post Office.
Outlook Express is configured for you automatically, just enter your
password.
                    Paclink AGW


Now it’s time for
Paclink AGW.
AGW is the
interface between
the Post Office
and the AGWPE
engine.

Choose “File” then “Properties” to begin configuring the AGW.
This is the AGW Properties screen. The only change you should
make is to verify the “PATH” to the AGWPE (remember where you
unzipped the files to?) is correct.
Click UPDATE.
Once the Properties are set, then choose “FILE, “Channels”. This is
the default screen. First, select Telnet (to configure a Telnet path for
Paclink.)
When you have an Internet connection, PacLink will use it FIRST to send and receive
email. If the Internet is unavailable, it can use 2m Packet. The Telnet Properties
displayed here is DIRECTLY out of the documentation. Once the entries are made,
Click ADD NEW CHANNEL.
Next, I am adding a VHF Packet channel. I named it “N5TW”. The channel priority
simply tells AGW which one to try first. (Telnet was 1, Packet is 5). Enter the Remote
Callsign, and in the AGWPE port, select the Drop-Down box for the AGWPE port we
just configured. I left all other options as default.
Directly under
the Remote
callsign is a
Connect Script
Box. This is
what I used to
connect to
N5TW via a
Digipeater.
Now that everything is
configured, it’s time to
test it.
Here, I’m testing the
initial Telnet connection
through my roadrunner
account.
Next, I’m testing my VHF
connection to N5TW. Once you’ve
tested your connections, it’s time to
send your first email.
Your email address will be your
callsign@winlink.org. Open
Outlook express (enter your
password) and send a test email to
anyone you wish. Once the email
goes out through the Telnet or VHF
packet path, your email will be
registered with Winlink. It may
take a few hours for this process to
complete. Once this is done, try
sending yourself an email to
yourcallsign@winlink.org . The
AGW is configured to check for
incoming mail every 60 minutes,
but you can manually initiate a
connection for testing purposes.
Here’s my first successful sending of a
test message. Most of this information
is cryptic, and you won’t need to
know what it means, but you can see
here the line –
K4CJX de KI5DR QTC 1
This tells the PMBO that I have one
message outgoing. Kinda cool, huh?
The bottom line is, get on the air and
try it out! Having lots of trained
Paclink operators will certainly help
out when the next disaster or
emergency happens.
