7. Troubleshooting
7.1 The Connection Issue
If the driver installation of I-7565-H1/H2 is successful, the virtual
com port will be assigned by Windows automatically. Then users can
use “I-7565-H1/H2 Utility” to connect to I-7565-H1/H2 module via the
virtual com port for CAN bus communication.
[Q1] When users open the virtual com port, if it shows the below error
message like Figure 6-1-1, there are two conditions for that.
(1) This com port is not existed in system and please check the
com port number again.
(2) If the virtual com port number is bigger than COM16, then
users need to copy the new version “
MSCOMM32.OCX
” file in
I-7565-H1H2 utility folder to “C:\WINDOWS\system32\” to
replace the old version file and then register MSCOMM32.ocx
again.
If it still failed, please check that the driver installation is completed
or the virtual com port is correct for I-7565-H1/H2.
Figure 6-1-1
:
Invalid port number
[Q2] When users open the virtual com port, if it shows the below error
message like Figure 6-1-2, it means that the com port is occupied by
other programs like VxComm Utility. Please “UnMap” the same com
port used in VxComm Utility and then click “Restart Driver” function
like Figure 6-1-3. After that, reset I-7565-H1/H2 and try to connect to
I-7565-H1/H2 again.
