Troubleshooting
Unable to Open the Port
When you start the running program you may get this error
message if the computer doesn’t get access to the COM port.
When you click on
OK
button, another message says the
program was unable to communicate with the DADS Terminal on
the determined port.
Click on OK button and the DADS application
will open in Retrieve mode.
To solve the problem, see with the IT manager
to troubleshoot the COM configuration and see
if the COM port number you choose is really
the right one.
Communication Time out
In case the DABS/DADS is not responding, or
the DABS is switched OFF, or the serial cable
was accidently disconnected, this warning is
displayed.
If
Retry
has no effect, check if your DABS is
switched ON and that it is connected to the PC
serial port.
If you work in TCP/IP mode, check if your COM Server is already switched ON.
Another kind of
Connection time out
can appear if the computer and equipment have not
the same grounding potential which disturbs the serial communication.
To avoid too much vibrations near the equipment, you should find a flat and more
stable table or purchase the
Damping Table
as additional part, See if there is no
windows or blowing air conditioning to close to the Ipht, close the windows or move
the Ipht to another place far from the air conditioning system.
For the grounding potential difference between the computer and the IPHT, you can
check if the Ipht and the computer power supplies are connected to grounded
230Vac power outlet. If the Power ground is OK and there is no improvement, maybe
then you should purchase the
SPOB
(communication galvanic isolation) to connect
between the COM port form the computer and Ipht.
