19 Chapter 2
The PCA-6186 is equipped with one or two high-performance 32-bit
PCI-bus Ethernet interfaces, which are fully compliant with IEEE 802.3/u
10/100 Mbps CSMA/CD standards. Also, PCA-6186 provides the option
of supporting single or dual 10/10/1000 Mbps Ethernet LANs. They are
supported by all major network operating systems. The RJ-45 jacks on
the rear plate provide convenient 10/100/1000 Base-T RJ-45 operation. If
users use dual LANs, the second LAN port, CN34, is located at top slot of
the I/O expansion ports.
2.8 Serial Ports (CN9: COM1; CN10: COM2)
The PCA-6186 offers two serial ports, CN9 as COM1 and CN10 as
COM2. These ports can connect to serial devices, such as a mouse or a
printer, or to a communications network.
The IRQ and address ranges for both ports are fixed. However, if you
want to disable the port or change these parameters later, you can do this
in the system BIOS setup.
Different devices implement the RS-232 standard in different ways. If
you are having problems with a serial device, be sure to check the pin
assignments for the connector.
