3.25 SIO Enable (CN69)
Table 3-26 lists the pin signals of the SIO Enable jumper header, which provides
3 pins, single-
row, with 0.079
" (2mm) pitch. Select 1-2 to enable SIO, 2-3 to disable SIO.
NOTE: The shaded table cells denote Ground. Default = jumper installed on 1-2.
3.26 UART Interface (CN70)
Table 3-27 lists the pin signals of the UART Interface header, which provides
10 pins, 2 rows, with
odd/even sequence and 0.100
"
(2.54mm)
pitch.
NOTE: The shaded table cells denote Power or Ground. This port supports only RS232.
