5.2 CLASSIFICATION CODE

Table 5.2 shows table of classification

code. Make sure to input classification code
in order, higher code and then lower code.

5.3 DATA INPUT TIMING

5.3.1 TIMING AT ONE TIME INPUT

MO
DE

Take in data in on level that strobe signal. Let on/off time of strobe signal be more than 20ms. Be in state of on.

And if data indefinite area is more than 5ms, turn strobe signal off in order to satisfy Figure 5.3.1 timing chart of one
time data input.

Precaution If Figure 5.3.1 timing chart is not satisfied, be careful because of possibility of taking in error

data.
