2.6 10/100/1000Base-T Ethernet (CN8 and CN34)
The PCA-6185 is equipped with one high-performance 64-bit PCI-bus
Ethernet interface, which are fully compliant with IEEE 802.3/u 10/100/
1000 Mbps CSMA/CD standards. They are supported by all major net-
work operating systems. The RJ-45 jacks on the rear plate provide conve-
nient 10/100/1000Base-T RJ-45 operation.
2.7 Serial Ports (CN9: COM1; CN10: COM2)
The PCA-6185 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.
Table 2.1: Serial port connections (COM1, COM2)
Connector Ports Address Interrupt
CN9 COM1 3F8*3E8 IRQ4
CN10 COM2 2F8*2E8 IRQ3
* default settings
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.
