Note. USB devices shouldn’t be directly connected to the J4 connector. Parvus USB/Audio CODEC Adapter can be used. In fact it provides for two USB standard connectors (but only USB1 is useful for this CPU) and furthermore it provides for a better ESD (Electric Static Discharge) and Over Current protection. Before using a different adapter please refer to the Parvus Customer Support Service
J8 for AC97 Audio port Section
J8 is a double row 9 x 2 pin with
AC97 Audio
Figure 14. J8 Connector layout
The SpacePC 1232 module provides one AC97 (Specification Revision 1.3, 2.0, and 2.1) audio interface adding audio capabilities to the PC/104 system. The Parvus Audio CODEC Adapter (but also any AC97 CODEC which supports an independent input and output sample rate conversion interface can be used) provides an AC97 and a CODEC for the SpacePC 1232 and should be connected between the audio device and the J8 connector via a flat ribbon cable.
