*1. The sensor would not be able to detect human who walks faster than 1.7m/s.
*2. Shall be tested/evaluated the performance of customer’s system which incorporates Grid-
EYE unit, and also checked the specification of the controller device to be connected.
*3. Shall be used CPEV cable with shield for RS485 communication line.
*4. Condition: detective temperature range 10 to 29 degC

2) human's coordinates (8 persons)
Grid-EYE unit outputs human's detected position with XY coordinates, and sequenti
ally outputs the coordinates for the detected number of person in clause 1) from
(Xad1, Yad1) in order.
Undetected data position is set to (0, 0).
Data (0, 0) to be determined/judged at system side whether undetected data (0, 0)
or detected data of coordinates (0, 0), based on the data for detected number of p
erson in clause 1);

-Be sure to use a twisted-pair cable with a shield.
-Be sure to ground a shield one side.
Be sure to be exclusive D-class grounding with ground resistance of 100ohm or less.
-Be sure to make wiring into cascade connection.
（Don't make wiring into star connection.）
-Be sure to be short-circuit between the send terminal(+,-) and the termination
terminal(E,E) of a sensor connected to the end of the wiring.
