Possible Causes
The imager and host
may not be configured
for the same interface
parameters.
The com port at the
host is not working or
not configured
properly.
The cable is not
connected to the
correct com port.
Inter-character delay
needs to be added to
the transmitted output.
The USB host may not
be active.
The MS7580 will not
operate from hub/host
power without host
communication.
The imager is not
receiving sufficient
power to support

specifications on page 34.
Solution
Check that the imager and the
host are configured for the same
interface parameters.
Check to make sure that the baud
rate and parity of the imager and
the communication port match
and the program is looking for
"RS232" data.
Check to make sure that the cable
is connected to the correct com
port.
Add some inter-character delay to
the transmitted output by using
the Configuration Guides
(PN 00-02544 and 00-05252).
Turn on the host device.
Verify adequate power is being
supplied to the imager.
