3.5.2. Function of Control Outputs
 You can set the function of control outputs and the In-position stability timer. You may change
the preset input port function to other function , or to switch to one of expanded functions.
◊ You may assign the same fucntion to multiple ports.
◊ If you require a function other than the shipping set, you may switch a preset function to a
required one. For example, you may increase the number of idle ports by combining the Output
DRDY and WRN into the Output NRM, or the Output OTPA and OTMA into the Output
OTXA, to increase the number of idle ports.
