3.10.3 Line2 Configurable Bi-direction I/O Circuit

In controlling I/O, the configurable bi-direction non-isolated IO circuit of Line2 can
be shown in Figure 3-56.
Note: The camera of MV-CA030-10GM/GC has no such function.
1. Configure Line2 to input pin
Logic 0 input level: 0~0.5VDC (GPIO2 pin)
Logic 1 input level: 1.5~30VDC (GPIO2 pin)
Please make sure the input voltage is not from 0.5V to 1.5V as the electric status
among the two values is not stable.
