| A1n | 8 | I/O | Port A, channel 1, high-speed negative signal |
| SEL | 9 | I | Port select pin. Internally tied to GND via 100-kΩ resistor. L: Port A to Port B H: Port A to Port C |
| C1n | 12 | I/O | Port C, channel 1, high-speed negative signal (connector side) |
| C1p | 13 | I/O | Port C, channel 1, high-speed positive signal (connector side) |
| C0n | 14 | I/O | Port C, channel 0, high-speed negative signal (connector side) |
| C0p | 15 | I/O | Port C, channel 0, high-speed positive signal (connector side) |
| B1n | 16 | I/O | Port B, channel 1, high-speed negative signal (connector side) |
| B1p | 17 | I/O | Port B, channel 1, high-speed positive signal (connector side) |
| B0n | 18 | I/O | Port B, channel 0, high-speed negative signal (connector side) |
| B0p | 19 | I/O | Port B, channel 0, high-speed positive signal (connector side) |
| NC | 1, 10 | NC | These are no connect pins but can be tied to VCC or GND |
(1) The high-speed data ports incorporate 20-kΩ pulldown resistors that are switched in when a port is not selected and switched out when the port is selected.
