14. USB Interface
The USB interface comes with two USB ports, which follow the UHCI/EHCI specification and are USB 2.0
compliant. You can expand the amount of USB connections by adding external hubs.
14.1 Connector
The USB ports are available through the X16 and X17 connectors (each 4 pins). To have the signals available
on the standard USB interface connectors, an adapter cable is required. An USB interface cable is available
from Kontron (KAB-USB-1, Part Number 96054-0000-00-0).
The following table shows the pinouts for the USB connectors.
Note:
To protect the external power lines of peripheral devices, make sure that
1
- the wires have the right diameter to withstand the maximum available current.
- to enclosure of the peripheral device fulfills the fire-protecting conditions of IEC/EN 60950.
To find the location of the USB ports on the MOPSPM104 board, please see the Appendix "Connector
Layout".
14.2 Limitations
The power contacts for USB devices on Pin 1 and Pin 4 are protected. They are suitable to supply connected
USB devices with a maximum of 500 mA power dissipation. Do not supply external USB devices with higher
power dissipation through these pins.
