6 Troubleshooting
6.1 PC connection problems
This section describes problems that you may encounter while
programming the unit.
Bad connection,
wrong COM port selected, bad USB to
RS232 converter.
Check the serial cable, to make sure it is making good
connection with the Ready-or-Not unit, and the PC serial port.
If the unit still fails to connect, check to make sure you are using the
correct COM port. The default number of the built-in serial port is
COM1, however this number may be different, especially if you are
using a USB to RS232 converter.
To display the list of ports available to your
system, from within the configuration utility,
click
and click the
dropdown box.
If your system has a large number of avail-
able ports (as in the example screenshot), it
is highly recommended that you unplug (or
disable) any Bluetooth devices, and uninstall
the Bluetooth software.
Click the ' button to refresh the list, select the first
port on the list, click ' ', then ' '. If the ' '
error persists, repeat the procedure for the remaining ports, until the
'
' is displayed in the status bar.
Port in use, wrong
port selected, improperly installed
USB to RS232 converter
Close any programs that
may be using the COM port you have
selected in the configuration utility (GPS, HotSync, etc).
