Audio Interface
Audio Connector (CN6)
AC’97 Audio signals are interfaced through the phone jacks combined into the CN6 connector.
These signals include Microphone line-in, line-in stereo, and line-out stereo. In addition to the
phone jacks, the IMB-8550 is also equipped with separate connectors for Analog/Digital outputs
and SPDIF inputs.
COM Port Connectors (COM1 to COM6)
The IMB-8550 provides six (6) serial ports, and the serial port operation mode can be configured
through an onboard jumper set (RS-232/422/485). The COM1 port is interfaced through one
DB-9 connector and the rest of the COM ports are interfaced through individual 10-pin male
headers. These serial ports facilitate the connection to serial devices or a communication
network, e.g., terminal console.
