(2)  The figure below shows the encoder wiring and the SW1 setting on the EZJ144 board at the use of the IJ 
Printer built-in power supply. 
 
(a)  When open collector output and the IJ 
Printer built-in power supply are used. 
(b)  When totem pole output and the IJ Printer 
built-in power supply are used. 
 
(3)  The figure below shows the encoder wiring and the SW1 setting on the EZJ144 board at the use of the 
dedicated power supply. 
●  The wiring for the dedicated power supply varies depending on the output interface of the encoder but 
can be the same depending on the power supply voltage. 
 
(a)  When open collector output and the 
dedicated power supply are used. 
(b)  When totem pole output and the dedicated 
power supply are used. 
 
●  The SW setting used for the dedicated power supply varies depending on the power supply voltage 
but does not depend on the output interface of the encoder.
