(3) Recommended specification of GPIO cable
Do not connect the No. 1 pin and No. 2 pin of GPIO contact. When these are
connected to the connector on the user's equipment, this equipment may not
Make sure to confirm connector specification before creating a cable by a user.
If a user connect a cable which was mistaken about connector specification to
this equipment, this equipment may not operate normally.
Prepare the GPIO cable that conforms to the recommended specifications shown below by a user.
Connector for GPIO
(*1) The maximum cable length is 1.5 m. The cable length should use less than 1.5 m.
(*2) Contact the shield ground of a cable to the conductor of a plug case(frame ground)certainly.
In addition, since all the GND pins of GPIO are the signal grounds, do not connect a shield
ground. If you do, it may occur the malfunction.
