10.3 Communication error
If LogWare is unable to communicate with the thermometer readout for any
reason, a communication error occurs. To resolve the communication error,
please check the following:
If you are using an RS-232 cable:
•
Is the COM port in use? – Make sure that the COM port is not currently
being used by another application. If there is a hot sync adapter for a PDA
connected to your computer, make sure the software that uses the adapter
is closed or that it is not trying to use the same COM port.
•
Is the correct COM port selected? – Make sure that the communication
cable is connected to the selected COM port on the computer.
•
Is the thermometer readout set to the right baud rate? – Make sure that the
thermometer readout’s baud rate matches the baud rate selected in
LogWare . Refer to the thermometer readout’s User’s Guide for more de
-
tails on how to set the thermometer readout’s baud rate.
• Is the right type of cable being used? – LogWare requires that a “null mo-
dem” cable be used to communicate with thermometer readouts. Refer to
the Digital Communication section of the thermometer readout’s User’s
Guide for more details on the correct type of cable to use.
• Is the thermometer readout turned on? – Make sure that the thermometer
is turned on. Use the buttons on the front panel of the thermometer to exit
from any open menu.
• Is the correct model selected? – Make sure that the selected thermometer
readout model matches the model of the thermometer readout being used.
Each thermometer has its own set of commands and some thermometer
readouts do not recognize the commands for other thermometer readouts.
If using the IR dongle:
•
Is the IR dongle connected to the correct COM port? – Make sure that the
IR dongle is connected to the selected COM port.
•
Is the correct type of IR dongle being used? – Make sure the correct type
of IR dongle is being used. LogWare cannot use IR ports that are built
into the computer. Refer to Using an IR dongle with LogWare for more
details.
•
Is the path between the IR dongle and the IR window of the thermometer
readout unobstructed? – Make sure that the IR dongle is placed in close
proximity of the thermometer readout’s IR window and that there are no
objects between them that could obstruct the signal. Refer to the IR com
-
munication section of the thermometer readout’s User’s Guide for more
details on the placement of the IR dongle.
•
Is the thermometer readout’s IR communication mode set properly? – The
IR port on some thermometer readouts can be configured to operate in
different modes. LogWare requires that the IR port be set to operate in
