4

S8B

Source Terminal. This pin can be an input or output.

5

S7B

Source Terminal. This pin can be an input or output.

6

S6B

Source Terminal. This pin can be an input or output.

7

S5B

Source Terminal. This pin can be an input or output.

8

S4B

Source Terminal. This pin can be an input or output.

9

S3B

Source Terminal. This pin can be an input or output.

10

S2B
