Restrictions on USB Communication
• The FP0R connected to the USB is recognized by the PC as that is connected through the COM port.
When multiple FP0R units are connected to one PC with the USB, they cannot communicate with the
PC simultaneously.
• The PC can communicate with the FP0R that was connected first only, and it cannot communicate with
the other FP0R.
• A USB HUB cannot be used for the connection.
6.1.2 Installation of USB Driver
USB drivers must be installed to connect the unit with the USB.
The installation procedures differ depending on the OS in the PC to be used.
Note:
For the PC with more than one connector, it may be requested to reinstall these two drivers if the
positions of the USB connectors are changed. In that case, reinstall the drivers.
Procedure of installing the driver (e.g.: Windows® XP)
1. Once the FP0R is connected, the following screen is displayed. Select “No, not this time”, and click
“Next>”.
