Is a dedicated cable necessary to monitor a PC and a device?
Mostly, the attached monitor cable (LE-25M1) can be used. Because the connector of the personal computer is Dsub 9-pin, it tends to be seemed that the monitor cable with Dsub 9-pin is required. However, most of devices being connected are Dsub 25-pin. Therefore, the attached monitor cable (LE-25M1) can be used.
If the both devices being measured have Dsub 9-pin connector, LE-259M1 (option) is required.
