have an antenna problem.
Remove the SIM card, place it into a cell phone and see if there is connectivity or 3G
data, or make a phone call if it has a voice subscription. This will also have the effect of
reseating the SIM card when it is reinstalled back into the modem.
Replace the SIM card with a known good one and test. On rare occasion, these go
bad too. Keep in mind that the modem is set up for a specific carrier. Placing an ATT
SIM card into a modem that was configured for CELLULAR ONE will not work.
Most Bloodhound hardware modem failures can be traced to an electrical storm or
local lightning strike event.

To enable the serial USB connection between the computer and the Bloodhound, the
user must load the serial USB driver program. It is imperative that the USB serial
driver be loaded into the computer before plugging in the USB serial cable to the
Bloodhound. If the USB serial cable is already connected, remove the USB cable
and then install the serial port driver. The driver can be found at
www.iballinst.com/ftp/usbkey or on the USB key installed in the front panel of the
Bloodhound. After loading the serial USB driver software, connect the USB cable to
the computer, then start the Gas Chart program. The program will search the serial
ports and connect to the Bloodhound.
If this is not successful, check in the computer’s Control Panel / Add or Remove
Programs list for SILICON LABORATORIES CP210x DRIVERS and remove all
instances of them. Then, with the BH USB cord disconnected, run the the driver install
program from the BH flash drive. After the driver install, plug in the BH USB cord and
start Gas Chart. The program will search the serial ports and connect to the
Bloodhound.
If still not successful, check what comm port the BH has been assigned to, as follows:
