4.5.2 Current output

Current outputs may be selected in the scales 0 to 10mA, 0 to 20mA, or 4 to 20mA. For

each scale, the minimum to maximum signal levels are represented by 4000 hex to C000

hex. Table 4-4 shows how signals from other wireless products translate to WI-I/O-EX-

1-S-13 current levels.
