How to read the binary output
The LK-G Series outputs the measurement value as a binary number (two’s complement) of 21
bits. The decimal point is ignored.
Example: When the measurement value is "+134.97"
• 13497 (decimal) → 0 0000 0011 0100 1011 1001 (binary)
Example 2: When the measurement value is "–134.97"
• –13497 (decimal) →1 1111 1100 1011 0100 0111 (binary)

LASER OFF input
Controls the laser for each head. For NPN type, the laser
is turned off when short-circuited with COM, and turned
on when open. For PNP type, the laser is turned off when
the voltage is applied, and turned on when the circuit is
open.
"LASER OFF A" controls the head A, and "LASER OFF B"
controls the head B.

REMOTE
This is the laser remote interlock terminal. The laser beam
is emitted when the terminal is short-circuited with COM,
and emission is stopped when the terminal is open. The
terminal is common to head A and B, and takes priority
over the LASER OFF input.
