AT-MIO-16E-10, AT-MIO-16XE-10, AT-AI-16XE-10, and 
AT-MIO-16XE-50 has 68 pins that you can connect to 68-pin 
accessories with the SH6868 shielded cable or the R6868 ribbon cable.  
With the SH6850 shielded cable or R6850 ribbon cable, you can 
connect your board to 50-pin signal conditioning modules and terminal 
blocks.
The I/O connector for the AT-MIO-64E-3 and AT-MIO-16DE-10 has 
100 pins that you can connect to 100-pin accessories with the
