J5 I/O Connector - VersaLogic Python EBX-11 Reference Manual

J5 I/O C
ONNECTOR
The 40-pin I/O connector (J5) incorporates the PWM interfaces, 16 digital I/O channels, and
eight analog channels. Table 5 shows the function of each pin.
Note
On Rev. 4 boards, the TACH input, PWM output, and Digital I/O 0-10 signals
were nonstandard. The signals were corrected in Rev. 5.00 boards. The standard
pinout is shown below. The nonstandard pinout is shown in Table 6.
