<Reference>
Described below is the procedure to perform each data port test individually.
1. Preparation
Same as DATA PORT check (automatic)
2. Setting
Same as DATA PORT check (automatic)
3. Check
Make the same initial setting as DATA PORT check (automatic) and perform REMOTE and MODEL ID checks.
After that, enter the number of the test to be executed by using the keyboard of Windows PC.
In this way, the DATA PORT tests can be performed individually.
