3.0 QUICK START GUIDE
3.1
Slide Power switch (8) to “On”.
3.2
Rotate Sensitivity Adjust knob (7) fully counterclockwise to
the “Auto” position.
3.3
Aim the laser dot perpendicular to the target - reflective tape,
contrasting color or keyway.
3.4
If the On Target LED (1) is not on, push and hold the Red
Learn/Gain button (6) until the On Target LED (1) blinks
regularly. Note that at higher RPMs the LED will be on solid.
3.5
If after completing step 3.4, the On Target LED (1) blinks
erratically or not at all, rotate the Sensitivity Adjust knob (7)
slowly from 1 to 9 until the LED blinks regularly or is on solid.
3.6
If after completing steps 3.1-3.5, the On Target LED (1) blinks
erratically or not at all:
3.6.1
Move the sensor closer to the target and ensure it is
perpendicular to the target. Repeat steps 3.1-3.5.
3.6.2
Increase the contrast/reflectivity of the target. Repeat
steps 3.1-3.5.
3.7
Once the On Target signal is obtained, use the Polarity Switch
(5) to select a compatible output pulse for your application.

To aid in locating the laser dot over a large distance, hold a piece of white
cardboard or equivalent in front of the laser. Progressively move the white
surface closer to the desired target. Then adjust the aim of the laser as necessary.
In areas of high ambient light (outdoors), performance can be enhanced at
long distances by slipping a piece of black tube with a minimum inner
diameter of 0.6 inches, over the nose piece to act as an extension nose piece.
This tube should not deflect the beam in any way.
8.0 RS232
Baud rate = 9600, 8 bits, 1 stop bit, no parity.
When the unit is turned on, it will send out: “SLS<lf><cr>Vx.x<lf><cr>
0.0<cr>”. Where <lf> is the linefeed character, <cr> is a carriage return
character, and x.x is the firmware version number.
The unit will send out the current RPM as a right justified 7-digit ASCII
number that will always include a decimal point followed by carriage return.
The update rate is a function of the speed of the target and will not exceed
twice per second.
Examples:
1234.56<cr>
123456.<cr>
_ _ _ _0.0<cr> ( _ = space character)
