BCD Output Timing Chart
A REQUEST signal from a Programmable Controller or other external device is required to read BCD data.
Single Sampling Data Output
The data is set in approximately 30 ms from the rising edge of the
REQUEST signal and the DATA VALID signal is output.
When reading the data from a Programmable Controller, start
reading the data when the DATA VALID signal turns ON.
The DATA VALID signal will turn OFF 40 ms later, and the data will
turn OFF 16 ms after that.
Continuous Data Output
Measurement data is output every 64 ms while the REQUEST signal
remains ON.
Note:
If HOLD is executed when switching between data 1 and data
2, either data 1 or data 2 is output depending on the timing of
the hold signal. The data will not go LOW.

DATA (including POL and

be used in a wired OR.
RUN, HH, H, PASS, L, and
LL are always output, with or
without a REQUEST signal.
Do not used a wired OR
connect for these signals.

Note:
The BCD output connector pin number is the D-sub connector pin number when
the BCD Output Cable (sold separately) is connected. This number differs from
the pin number for the Digital Indicator narrow pitch connector (manufactured by
Honda Tsushin Kogyo Co., Ltd.).
Refer to the following User's Manual for application precautions and other information required when using the Digital Indicator:
