2.4.7 J11 I/O Expansion Interface

The I/O Expansion connector provides additional capability for LPC, TERM2, M/C, CAN, and

HSS/UART interfacing. All signals on this connector are at TTL levels which means that they

will require additional signal conditioning prior to interfacing to VMP3 external devices.
