This chapter also lists step-by-step instructions on producing each report both on-site and
off-site . The instructions for each report start with you being at the Main menu, which is
described below.
1 If on-site :
a If COM3 has nothing plugged in it, plug your computer into it.
b If COM3 has something plugged into it, unplug what is connected to COM3 and
plug your computer into it.
2 If off-site , plug your computer into a modem that is plugged into a nonswitched analog
telephone line.
3 Turn on your computer.
4 Be sure that your computer has installed communications software, that it is set to use
full duplex, and that the baud rate is set correctly.
If on-site , the baud rate of your computer must match the baud rate of the selected
serial port because they are in direct, one-to-one, communication with one another.
For example, the baud rate for COM3 was set to 9600 at the factory. If the customer
changed this baud rate, your computer must be set to the changed value.
For off-site connections, the baud rate of your computer doesn't have to match the
baud rate of the selected serial port because the telephone network between the two
modems breaks this direct physical connection. In an
off-site setup, your computer
and its modem have a direct connection, the two modems have a direct connection,
and the detector and its modem have a direct connection. Each of these individual
direct connections must have matching baud rates. However, the different connection
"types" (user computer to modem, modem to modem, detector to modem) don't have
to share a common baud rate (although it's simpler if they do).
Opening a LOG file captures the whole session to the file. Then, when your session is
done, you can view what you have done with an editor, print it with a printer, or store it
for later retrieval.
5 On your computer, open a LOG file.
6 If off-site :
a From your computer, dial and connect to the modem at the site to which you want
to communicate.
b Wait for the "connect" message from your modem.
