NOTE
All input and output signals excluding BCD 00 to 03, BCD 10 to 13, and the
power supply are all negative logic.
(1) TRIG
______
When the 3511-50 is set to external trigger mode, a negative logic signal is
input from outside via this line. Testing is initiated once when this signal
goes low level.
(2) BCD00, BCD01, BCD02, BCD03
For the panel number to load, choose the ones digit.
When a trigger signal is input in external trigger mode, the panel chosen is
read and measurement begins.
(3) BCD10, BCD11, BCD12, BCD13
Choose the tens digit for the panel number to be loaded.
When a trigger signal is input in external trigger mode, the panel chosen is
read and measurement begins.
All other combinations are invalid.
Example: When reading panel 15, set "0001 0101."
*1 *2 *1: Digit of 10, *2: Digit of 1
Because the open state is "1", when specifying the panel number, be sure to set all
signals.
(4) M-HI
_____
, M-IN
_____
, M-LO
______
These lines output the comparator result for the first parameter.
(5) S-HI
_____
, S-IN
_____
, S-LO
______
These lines output the comparator result for the second parameter.
(6) AND
_____
This line outputs the logical AND of the comparator results for the first
parameter and for the second parameter. This signal is output only if both
the comparator results are IN.
