2.710/100Base-T Ethernet Connectors (CN8 and CN34)
CN8 and CN34
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 expension ports.
2.8 Serial Ports (CN9: COM1; CN10: COM2)
CN9 and CN10
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.
