Description
Examples
SPRR
Set Pulse Repetition Rate — Sets the pulse repetition rate.
The units are in Hz. The pulse width and the duty cycle
(dependent on the pulse width and pulse repetition rate)
must be within the specified range. The response from the
laser is the command echoed back, a delimiter of ―:‖, and
then the pulse repetition rate. A value that is outside the
acceptable range receives a response of ―ERR: Duty cycle
too high, max.duty cycle XX.X%.‖
Sent
：
―SPRR 10‖
Response
：
―SPRR: 10‖
(PRR is set to 10Hz)
Sent
：
―SPRR 100‖
Response
：
―ERR: Duty cycle too
high‖
SPW
Set Pulse Width — Sets the pulse width. The units are in
milliseconds (ms). The pulse width and the duty cycle must
be within the specified range. Can only be set to integer
multiple of 0.02ms.
Sent
：
―SPW 5.5 ‖
Response
：
―SPW: 5.5 ‖
STA
Read device status status—The status is reported as a
bit-encoded 32-bit word. Undefined bits or bits defined as
―Reserved‖ can be in any state and should be ignored.
Each of the bits have the following meaning
Bit 0
-
0
=
Normal operation
-
1
=
Command Buffer Overflow
Bit 1
-
0
=
Normal operation
-
1
=
Overheat
Bit 2
-
0
=
Emission Off
-
1
=
Emission On
Bit 3
-
0
=
Back Reflection OK
-
1
=
High Back Reflection level
Bit 4
-
0
=
Analog Power Control
Disable
-
1
=
Analog Power Control Enable
Bit 5
-
0
=
Normal operation
-
1
=
Pulse Too Long
Bit 6
-
Reserved
Bit 7
-
Reserved
Bit 8
-
0
=
Aiming Beam OFF
-
1
=
Aiming Beam ON
Bit 9
-
0
=
Normal operation
-
1
=
Pulse Too Short
Bit10
-
0
=
CW Mode
-
1
=
PULSE Mode
Bit 11
-
0
=
Power Supply OK
-
1
=
Power Supply Out of Range
Bit 12
-
0
=
Modulation Disable
-
1
=
Modulation Enable
Sent: ―STA‖
Response: ―STA: 4100"
This translates to the following:
4100 = 0x1004, so bits 2 and 12
are set. This means that emission
is on and modulation is enabled.
