8-46 IETG FlowHawk Manual
Problem Monitor cannot communicate over a serial connection.
Possible
Causes
Serial connection to monitor or field computer may be
loose.
Direct Connect Cable may be damaged.
Serial port on the computer may not be generating
adequate power for the Direct Connect Cable to
facilitate communication with the monitor.
3.3-volt fuse on regulator may have blown.
Possible
Solutions
Verify cable connections to monitor and field computer
are secure.
Inspect the Direct Connect Cable for damage.
Run a USB-to-serial adapter cable between the
computer’s USB port and the Direct Connect Cable.
(applies only if the software provides a “Getting Monitor
Attention” message while attempting to communicate)
Remove the monitor from the hazardous area (at least
6.1 meters away from the manhole), disconnect the
battery pack, wait at least 1 minute, reconnect the
battery pack, and then attempt to communicate. If the
monitor still will not communicate, replace the 3.3-volt
yellow fuse (when replaceable) on the regulator or send
the unit back to IETG for power regulator replacement.
