4.4 WI-I/O-EX-12 configuration
4.4.1 Voltage input
Voltage inputs may be selected in the scales 0 to 5V, 0 to 10V, or 1 to 5V. For each scale,
the minimum to maximum signal levels are represented by 4000 hex to C000 hex. Table
4-1 shows how the WI-I/O-EX-12 voltage readings translate to outputs in other wireless
products.
