Do not stare directly into the laser beam or the reflected light.
For
targets greater than 5 feet and up to 65 feet from the sensor, mount the
laser on a tripod using the ¼ - 20 bushing on the bottom of the unit and
attach T-5 reflective tape to the target.
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)
