Interfacing to a computer
and firmware updates
The Eagle provides a standard USB 2.0
interface for two purposes:
1. Connection to a PC or other USB Hub
device for control or logging or monitoring
purposes.
2. Connection to a PC for firmware updates
using the standard TenTec upgrade utility.
The physical interface used to connect with
the Eagle is a standard USB cable. A standard
USB cable will have a type A connector for
the computer / Hub and a USB type B
connector for the Eagle.
The software interface for the Eagle uses the
standard usbser.sys driver supplied with
windows up through Windows 7. Therefore
no special drivers or programs are required to
update or communicate with the Eagle other
than the standard Update program supplied by
TenTec. However, a “.inf” file supplied by
Microchip is required to inform Windows
how to utilize the standard usbser.sys file.
This “.inf” file is available via the TenTec
download
web
page,
starting
from
www.tentec.com.
The steps to follow to install the USB driver
vary depending upon the version of Windows
you are using. Some versions of Windows
allow you to “browse” to a driver or .inf file,
some don’t. If your Windows allows this,
then the first set of steps is the best method of
installing the driver. If it doesn’t, then the
second set of steps is the best method of
installing the driver.
The steps to install the driver for most
Windows versions up through some Windows
Vista versions is as follows (Note: depending
upon your security settings, you may need to
do this using an account with administrator

and the PC.
