2.5 Serial Ports (2F-CN3, CN5, CN4, CN6)The MIC-3318 offers two serial ports: both support RS-232/422/485
modes (jumper selectable) via two DB-9 connectors seperately. These
ports allow users to connect to serial devices or a communication
network.
You can select the address for each port to disable it, using the BIOS
Advanced Setup program, covered in Chapter 4. Different devices
implement the RS-232/422/485 standard in different ways. If you are
having problems with a serial device, be sure to check the pin assign-
ments for the connector. The IRQ and address range for both 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. The table
below shows the settings for the MIC-3318 board's ports:
Table 2-1: MIC-3318 serial port default settings
Port Address Interrupt Default
COM1 3F8, 2F8, 3E8, 2E8 IRQ4/IRQ3 3F8/IRQ4
COM2 3F8, 2F8, 3E8, 2E8 IRQ4/IRQ3 2F8/IRQ3
2.6 Ethernet Configuration (2F-RJ1, RJ2)The MIC-3318 is equipped with a high performance 32-bit PCI-bus
Gigabit Ethernet interface which is fully compliant with IEEE 802.3u 10/
100/1000Base-TX specifications.
2.7 USB Connector (1F-CN15, CN16)The MIC-3318 provides two USB (Universal Serial Bus) 2.0 channels
via two ports on the front panel, which give complete plug and play,
hot attach/detach ability for up to 127 external devices. The USB
interfaces comply with USB specification rev. 2.0 and are polyswitch
protected.
The USB interfaces can be disabled in the system BIOS setup.
