BCD POLE output
BCD polarity output.
OFF: Positive
ON: Negative
BCD DIGIT output
BCD numeric output for each digit.
Negative logic (i.e., Turns ON (set to 1) when NPN
open connector output is ON).
Comparator waiting status (with "–" displayed for
each digit): All digits set to B (1011)
Overrange (with "F" displayed for each digit): All
digits turn ON (1111).
BCD INDICATE
OUT1/2 output
Present OUT number turns ON.
OFF : OUT1
ON : OUT2
BCD SELECT
OUT1/2 input
Select and input the OUT number to be output.
OFF (Open) : OUT1
ON (Short-circuited to COM2 terminal) : OUT2
STROBE output
Output in synchronization with determined BCD
output.
