The Hpgcomm Connectivity Program - HP 39g Master Manual

The HPGComm Connectivity Program

At this stage I will assume that you have an
hp 38g, hp 39g or hp 40g and you have installed
the Connectivity software on your computer and
have run it. If you have an hp 39g+ then the
software will be similar in behavior although the
appearance of the screens may be different. See
page 181.
When you run the software you should see the screen shown above.
If you receive the error message right then it means that the default serial
port COM1 is unavailable. Press OK and try
changing to a different one from the list on
the screen. You should read the comments
below first.
Many computers released since 2002 only have USB ports. This was the
reason why the hp 39g+ was altered so that it uses the USB port. If you own
one of the earlier models this means that you will be unable to plug in the
cable since it requires a COM port. If this is the case then you will need to
buy a USB to Serial adaptor. Unfortunately these often cost more than the
cable, but it will solve the problem.
If you are using the software on a school network then you may need to talk
to the network administrator. Some school networks lock out ports for
security reasons. Discuss your problem with the network administrator.
You can test whether the program is working
by performing a screen capture (more on this
later). Connect up the cable to the calculator,
being firm but careful when plugging it into the
top of the calculator so as not to bend the pins.
Turn the calculator on and press ON+1. This
means "press and hold down ON and, while
still holding it down, press 1". If the connection
is working correctly then a captured image of
your calculator screen will appear. If it doesn't then check that you have fresh
batteries in the calculator and investigate the use of a different serial port.
