The name of the output file is the same as the input file when converting to ASCII or binary formats.
The file extension, however, is altered to indicate the format of the data:
*.asc for ASCII
*.bin for binary
When converting to RINEX, the output files are named according to the RINEX Version 2.10 naming
convention, see Section 6.3.1, Rinex Format on Page 105.
The -batch arguments suppress the window display and convert the specified file automatically.
When converting to RINEX in batch mode, the navigation and observation file header
information from the most recent interactive Convert session is used.
6.4 USB Drivers Installation
The NovAtel USB PC Driver Kit contains the following:
ngpsser.sys This driver provides a virtual serial port for each USB port of the receiver.
ngpsusb.sys This driver connects the virtual serial ports to the USB stack.
novatelusb.exe This utility allows you to control which Windows COM ports are assigned
to each USB port of the receiver. This utility can also be used to uninstall
the drivers when newer versions are available. During installation, a short-
cut is added to the Start Menu under Programs/OEMV PC Software/NovA-
tel USB Configuration Utility.
These drivers have not been certified by Microsoft's Windows Hardware Quality Lab
(WHQL). Depending on your computer's Driver Signing Policy, Windows may refuse to
install this driver or may display a warning. See Section 6.4.1, Windows Driver Signing below
for details.
6.4.1 Windows Driver Signing
Depending on how your administrator has configured your computer, Windows 2000 and Windows
XP either ignore device drivers that are not digitally signed, display a warning when they detect
device drivers that are not digitally signed (the default), or prevent you from installing device drivers
without digital signatures.
Since the current version of NovAtel USB drivers are not digitally signed, the computer's policy must
be either Ignore or Warn to enable the drivers to be installed.
To change the Driver Signing Policy on your computer:
1. Double-click on System in the Control Panel.
2. Select the Hardware tab.
3. Click on the Driver Signing button
