Check other program or devices that use
the COM port, and ensure that they do not
conflict with the interrupt request (IRQ) or
the COM settings.
Parity error detected. Serial cable becomes disconnected during
a serial download. Ensure the serial cable is properly
connected, and try the download again.
Cannot obtain com port. The wrong COM port has been chosen with
the native serial driver (either Serial 1 or
Serial 2). Select the correct COM port.
The COM port is assigned to an enabled
INTERCHANGE port and is trying to be
used with the native serial driver (Serial 1 or
Serial 2). Choose the INTERCHANGE port. Or
disable INTERCHANGE, reboot, and
choose the native serial driver.
Unable to communicate with terminal. During a serial upload/download, the
PanelView terminal is not in the Transfer
Application screen. Check that you are in configure mode. On
the PanelView terminal, check that you are
in the Transfer Application screen and you
have selected the Serial tab.
Wrong baud rate. Check that the baud rate, parity, and error
settings on the Transfer Setup screen
correspond with the host computer settings.
You cannot perform a serial download. Check that the COM port you are using is
enabled by your Windows operating
system. This can be done by checking the
Ports settings under Control Panel. For
more information, refer to your Windows
3.1, Windows 95, or Windows NT user
documentation.
Check if you are using the same COM port
that your mouse is using. Typically, the
mouse is plugged into COM 1; however, it
may be plugged into COM 2. Check the
labelling on the rear of your computer to
determine which port the mouse is hooked
up to and which port your upload/download
cable is hooked up to.
Check if the COM port you are using is
using the same IRQ number as another
device in your system. Possible causes of
conflict are PCMCIA device cards, Ethernet
cards, sound cards, or other PC add-on
cards. To determine the IRQ settings for
your serial port, refer to your computer’s
user documentation.
Check the settings for the port in the Control
Panel, and check that the settings match.
Then check the IRQ settings for the other
devices listed above to ensure there is not a
conflict.
If you have been using another software
package to access the serial port (such as a
communications package, A-B 6200
software, or even INTERCHANGE), you
may need to restart the computer. To do
this, close the application using the serial
port, disconnect the cable, attach the
PanelView upload/download cable, restart
your computer, and retry the download.
