Operating Voltage Setting - NEC IE-703002-MC User Manual

2.4 Operating Voltage Setting

(1) JP3
The operating voltage range of the IE-703002-MC is set using JP3 in the pod. When the IE-703002-MC is used
for developing application systems using the V852, V853 and V850/Sxx products keep JP3 as its factory-set
position.
Remark The JP3 settings are as follows.
Shorted
(factory-set)
Open
When the power of the target system is off or the IE-703002-MC is operated on a stand-alone basis,
the operating voltage of the IE-703002-MC differs depending on the JP3 setting. (2-3 of JP4 shorted.)
Status of JP3
Shorted
Open
Therefore, if the IE-703002-MC is operated with an option board connected while JP3 is shorted, the
option board, which should operate at 3.3 V will be damaged because 4.7 V, which is above the
absolute maximum rating, is applied. It is therefore important to pay attention to the JP3 settings.
When the IE-703002-MC is used for developing application systems using V850/Sxx products by connecting an
option board, apply the settings specified in the user's manual of the option board used.
