The answer to the
NN
STS
command is:
“
NN
<STX>
C
1
C
2
C
3
C
4
<ETX>”
where
C
1
C
2
are the ASCII representation of byte
B
1
de-
scribed below (e .g .
B
1
= 0xF3
C
1
= “F”,
C
2
= “3”),
C
3
C
4
are the ASCII representation of byte
B
2
described
below (e .g .
B
2
= 0x1D
C
3
= “1”,
C
4
= “D”) .
The meaning of
B
1
and
B
2
is:
B
2
bit 0
alarm relay
(1: energized, 0: de-energized)
B
2
bit 1,2 red LED
(bit 2 = 0 and bit 1 = 0: LED is OFF;
bit 2 = 1 and bit 1 = 0: LED is fixed ON;
bit 2 = 1 and bit 1 = 1: LED blinks)
B
2
bit 3
relay #1 (1: energized, 0: de-energized)
B
2
bit 4
relay #2 (1: energized, 0: de-energized)
B
2
bit 5
relay #3 (1: energized, 0: de-energized)
B
2
bit 6
relay #4 (1: energized, 0: de-energized)
B
2
bit 7
hold digital output (1: ON, 0: OFF)
B
1
bit 0
control (1: ON, 0: OFF)
B
1
bit 1,2 setup mode
(bit 2=0 and bit 1=0: not in setup mode;
bit 2=1 and bit 1=0: setup mode, view only;
bit 2=1 and bit 1=1: setup mode, unlocked)
B
1
bit 3
calibration mode with device unlocked
(1: yes, 0: no)
B
1
bit 4
setup updated
(set to 1 after a device power-up or a device reset or a
change in setup made through the instrument keyboard;
reset to 0 after receiving a GET command)
B
1
bit 5
calibration mode
(set to 1 after a device power-up or whatever complete
calibration; reset to 0 after receiving a CAR command)
B
1
bit 6
hold mode (1: ON, 0: OFF)
B
1
bit 7
free for future use (and set to 0)
