The IX-brick has two standard serial ports. As an option, two additional serial ports can
be added to the IX-brick. These ports are capable of transferring data at rates as high as
230 kbps. Other features of the ports include the following:
• Programmable data, parity, and stop bits
• Programmable baud rate and modem control
The Cx-brick has one console port that connects the Cx-brick L1 controller to a system
console.
Both the serial and console ports use a DB9 connector (see Figure A-3).
