NOTE
1 Commercially available USB devices are prone to
compatibility problems with personal computers to
some degree. It is not guaranteed that every
commercially available USB device can operate
properly with personal computers. Machine tool
builders are requested to check the operability of
the USB devices they select. Keep in mind that
commercially available USB devices are generally
neither dust-proof nor moisture-resistant.
2 The maximum supply current from each USB port
is 500 mA/port.
The maximum supply current to peripheral devices
is 1400 mA in total. The peripheral devices include
the PCI extension board, PCMCIA card, and
mouse.
3 The signals of USB port 1 and 2 are connected to
the connector explained in Section 4.4. When one
of the ports is used, the other port cannot be used.
