5.3 BCD Output TS-0323
The BCD output and DAV command output of the TS-3200A are all open-collector outputs.
The following explains signals as logic recognized by the external device assuming that the BCD output
and DAV command are connected to the external device through the recommended interface.
Note: Total length of cable connected to BCD OUT shall not exceed 5m.
5.3.1 Description of Each Signal
1
Data output
CH1: The decimal point is not output.
CH2: The decimal point is not output.
Positive logic 5-digit parallel output
Open-collector output
2
Polarity output
CH1 42 pins (- output) / 43 pins (+ output)
CH2 44 pins (- output) / 45 pins (+ output)
Open-collector output
When measured data is positive (+), pins 42 and 44 (- output): Lo (ON)/ pins 43 and 45 (+ output): Hi
(OFF)
When measured data is negative (-), pins 42 and 44 (- output): Hi (OFF)/ pins 43 and 45 (+ output): Lo
(ON)
3
DAV command output
Open-collector output
Outputs the DAV command signal with negative logic pulse while the BCD output data is being updated.
(Refer to the timing chart.)
4
Hold input
When the contact close (Lo level) signal is input, the BCD output data is held. The hold state is retained
while this signal holds the contact close condition (Lo level).
Also in the hold state, the count circuit performs the count operation according to the input signal from
the torque sensor. Therefore, when the hold state is canceled, the BCD output data changes to the
measured data at that timing.
