Table 31: FlexPak6 I/O Port Pin-Out Descriptions
The FlexPak6 provides an output voltage on pin 4 of COM2 (POUT) that matches the
voltage used to power the FlexPak6.
The FlexPak6 can accept voltages up to 36 VDC, which is greater than the RS-232 specified
maximum 25 VDC. As a result, you can damage equipment that is connected to COM2 by
sending voltages higher than the RS-232 specification allows.
