1.5.1 USB Connectors
The MIC-3393 provides up to seven Universal Serial Bus (USB) 2.0 channels. Two
front panel USB ports, CNUSB1 and CNUSB2. One is routed to an on-board USB
flash disk. Four other USB channels are routed to rear I/O via the J3 connector. Two
on the panels, the other two are on-board connectors. However, RIO-3311-A1E only
supports one on-board USB port due to space limitation. The USB interface provides
complete plug and play, hot attach/detach for up to 127 external devices. The MIC-
3393 USB interface complies with USB specification R2.0 and is fuse protected (5 V
@ 1.1 A). The USB interface can be disabled in the system BIOS setup. The USB
controller default is set to "Enabled".
1.5.2 Serial Ports
The MIC-3393 provides one serial port and the RIO-3311 provides two serial ports.
They are available as RS-232 interfaces via RJ-45 connectors on the front panel. An
RJ-45 to DB-9 adaptor cable is provided in the MIC-3393 accessories to facilitate
connectivity to external console or modem devices. The BIOS Advanced Setup pro-
gram covered in Chapter 2 provides a user interface for features such as enabling or
disabling the ports and setting the port address. Many serial devices implement the
RS-232 standard in different ways. If you have problems with a serial device, be sure
to check pin assignments on Table 1.12 for the connectors. The IRQ and address
range for these ports are fixed. However, if you wish to disable the port or change
these parameters later, you can do this in the system BIOS setup.
